Do Goldfish Eat Algae? Tank Control Guide

Goldfish, a common species in home aquariums, often encounter algae growth within their tank environments. The presence of algae, a simple plant-like organism, frequently raises the question: Do goldfish eat algae? Understanding the dietary habits of Carassius auratus, the scientific name for goldfish, is crucial for effective tank management. Furthermore, proper algae control is essential for maintaining the health and aesthetic appeal of aquariums, and sometimes, the introduction of an algae eater tankmate becomes necessary.

Understanding Algae Growth in Aquariums: A Comprehensive Guide

Algae, a common presence in aquatic environments, often becomes an unwanted guest in our carefully curated aquariums. Understanding its nature, the factors that promote its growth, and the various types that can appear is crucial for maintaining a healthy and aesthetically pleasing tank.

Algae encompasses a diverse group of simple, plant-like organisms capable of photosynthesis.

In the aquarium context, algae are generally defined as any photosynthetic organism that is not intentionally introduced as a decorative plant. They range from single-celled organisms forming cloudy water to multicellular forms creating unsightly coatings on tank surfaces.

While algae are a natural part of many ecosystems, their uncontrolled proliferation in aquariums is often considered undesirable for several reasons. Excessive algae growth can detract from the visual appeal of the aquarium, obscuring the view of fish and decorative elements.

More significantly, dense algae blooms can negatively impact water quality.

Algae consume nutrients, but their subsequent decomposition after a bloom can release those nutrients back into the water, potentially leading to imbalances and further algae growth.

Photosynthesis is the driving force behind algae growth. Algae use light energy to convert carbon dioxide and water into sugars for energy, releasing oxygen as a byproduct.

The availability of light, along with essential nutrients, directly influences the rate at which algae grow and spread.

Factors Contributing to Algae Blooms: Unlocking the Causes

Algae blooms are rarely spontaneous events. They are usually triggered by a combination of environmental factors that favor algae growth over other organisms within the aquarium.

Understanding these factors is essential for preventing and controlling algae problems.

The Impact of Aquarium Lighting

Lighting plays a pivotal role in algae growth. Algae utilize specific wavelengths of light for photosynthesis.

The spectrum, intensity, and duration of light exposure all influence the rate at which algae proliferate.

Excessive lighting, particularly in the blue and red spectrums, can stimulate rapid algae growth.

Long photoperiods (the duration of light exposure each day) also contribute to algae blooms by providing algae with extended opportunities for photosynthesis.

The Significance of Water Quality

Water quality is another critical determinant of algae growth. High levels of ammonia, nitrite, and nitrate—byproducts of fish waste and decaying organic matter—can act as fertilizers for algae.

These compounds, especially nitrates, provide algae with the nitrogen they need to synthesize proteins and other essential molecules.

An imbalance in pH can also indirectly affect algae growth.

Extreme pH levels can stress aquatic plants, making them less competitive for nutrients and allowing algae to flourish.

Nutrient Imbalance: Fueling the Bloom

Nutrient imbalance, especially an excess of nitrates and phosphates, is a primary driver of algae blooms.

Nitrates are a common byproduct of the nitrogen cycle, while phosphates can enter the aquarium through tap water, fish food, and certain aquarium additives.

When these nutrients are present in excess, algae have an abundant supply of resources for rapid growth.

The Role of Overfeeding

Overfeeding is a common mistake among aquarium hobbyists that can indirectly contribute to algae problems.

Uneaten food decomposes, releasing ammonia, nitrite, and ultimately nitrate into the water. This elevated nutrient load creates an environment that favors algae growth.

Common Types of Algae Found in Aquariums: Identifying the Culprits

Identifying the specific type of algae plaguing your aquarium is crucial for selecting the most effective control methods. Different algae species have different growth habits, nutrient requirements, and sensitivities to various treatments.

Green Algae

Green algae is a broad category encompassing various species that appear green due to the presence of chlorophyll. It can manifest as green water (single-celled algae suspended in the water column), green spots on the glass, or stringy filaments.

Control methods include reducing light exposure, improving water circulation, and introducing algae-eating snails.

Brown Algae (Diatoms)

Brown algae, also known as diatoms, typically appears as a brownish coating on the glass, substrate, and decorations.

It is often prevalent in newly established aquariums due to high levels of silicates in the water.

Remedies include regular water changes, reducing silicate levels, and introducing algae-eating snails.

Hair Algae

Hair algae refers to various filamentous algae species that form long, hair-like strands.

It can be challenging to eradicate once established.

Strategies for control include manually removing the algae, improving water circulation, reducing nutrient levels, and introducing algae-eating fish or invertebrates.

Black Beard Algae (BBA)

Black Beard Algae (BBA) is a particularly persistent type of red algae that appears as dark, tufted growths on plants, decorations, and substrate.

It is often associated with fluctuating CO2 levels and poor water circulation.

Solutions involve improving water circulation, spot-treating with liquid carbon dioxide, and manually removing the algae.

Blue-Green Algae (Cyanobacteria)

Blue-Green Algae, more accurately termed Cyanobacteria, are not true algae but rather photosynthetic bacteria.

They often appear as a slimy, blue-green or black coating that can quickly spread across the aquarium.

Distinguishing it from true algae is crucial, as treatment approaches differ.

Cyanobacteria are often triggered by low nitrate levels, poor water circulation, and excessive light.

Effective treatment approaches include improving water circulation, performing large water changes, reducing light exposure, and using antibiotics specifically designed for cyanobacteria.

The Role of Goldfish in Algae Control: Fact vs. Fiction

Many aquarium keepers introduce goldfish to their tanks with the expectation that these fish will diligently consume algae, keeping the environment pristine. However, the reality of goldfish as algae eaters is more nuanced than often perceived. Let’s delve into the facts surrounding this popular belief and discuss the crucial considerations for maintaining a balanced aquarium when goldfish and algae coexist.

Can Goldfish Eat Algae?: Unpacking the Myth

Goldfish are indeed omnivores, meaning their diet consists of both plant and animal matter. While they might nibble at algae present in the tank, it’s essential to understand that they are not primarily algae eaters.

Their dietary preferences lean more toward commercially prepared fish food, small invertebrates, and decaying organic matter.

While goldfish may opportunistically consume certain types of algae, they are unlikely to provide effective or consistent algae control. Relying solely on goldfish to manage algae is generally not a successful strategy and can lead to other issues.

Goldfish do not possess specialized digestive systems for efficiently processing large quantities of algae.

Their infrequent consumption of algae is unlikely to make a significant difference in controlling algae growth.

Limitations of Goldfish as Algae Eaters

There are several reasons why goldfish are not reliable algae controllers. First, their preference for other food sources means they’ll often ignore algae if other options are available.

Secondly, goldfish produce a significant amount of waste, which, ironically, contributes to the nutrient load in the tank, potentially promoting algae growth rather than reducing it.

Finally, goldfish are not selective eaters and may uproot plants or stir up substrate in their search for food, further disrupting the aquarium environment and increasing the likelihood of algae blooms.

Therefore, solely relying on goldfish for algae control is not a viable solution.

Algae Types Goldfish Might Consume

While not dedicated algae eaters, goldfish may occasionally consume certain types of algae. Softer, less fibrous green algae, like those found on the glass or decorations, might be grazed upon.

Diatoms, also known as brown algae, which often appear in new tanks, might be eaten as well.

However, tougher algae, such as black beard algae (BBA) or hair algae, are generally avoided by goldfish due to their texture and composition.

Considerations for Keeping Goldfish and Algae Together: A Balanced Approach

If you choose to keep goldfish in a tank where algae are present (or likely to appear), creating a balanced environment is essential for the health of your fish and the overall stability of the aquarium.

Appropriate Tank Size

Goldfish require ample space to thrive. Overcrowding leads to poor water quality and increased stress. Common goldfish (like comets) need a minimum of 75 gallons for the first fish and an additional 50 gallons for each subsequent fish.

Fancy goldfish varieties, while smaller, still require a minimum of 20 gallons for the first fish and 10 gallons for each additional fish due to their higher bioload.

Adequate space is critical for maintaining stable water parameters and minimizing the impact of goldfish waste on algae growth.

Maintaining Ideal Water Parameters

Goldfish are sensitive to water quality fluctuations. Regular testing and maintenance are crucial for their well-being.

The ideal temperature range for goldfish is typically between 68°F and 74°F (20°C – 23°C). The pH should be kept between 6.5 and 7.5.

Ammonia and nitrite levels should always be at zero, and nitrate levels should be kept as low as possible through regular water changes.

Preventing Overpopulation

Overpopulation in a goldfish tank can lead to a cascade of problems, including elevated waste levels, increased algae growth, and disease outbreaks.

Controlling the population through responsible breeding practices or choosing fish that are sexed can help prevent overpopulation. Avoid adding too many goldfish to a single tank, as the water quality will rapidly deteriorate, creating an unstable environment.

By understanding the limitations of goldfish as algae eaters and implementing proactive measures to maintain a balanced aquarium ecosystem, hobbyists can create an environment where both goldfish and (controlled) algae can coexist.

Alternative Algae Eaters Suitable for a Goldfish Tank: The Clean-Up Crew

While goldfish may not be the most reliable algae eaters, the need for algae control in a goldfish tank remains. Fortunately, there are alternative algae-eating tankmates that can effectively contribute to a cleaner aquarium environment without posing a threat to your goldfish. These dedicated algae consumers offer a practical solution for maintaining a balanced and aesthetically pleasing aquatic ecosystem.

Snails are often overlooked, but they can be highly effective algae eaters in an aquarium setting. These invertebrates tirelessly graze on various surfaces, consuming algae and detritus.

The introduction of snails provides a natural and sustainable method for managing algae growth. A variety of snail species are commonly employed in aquariums, each with its own unique characteristics and preferences for different types of algae. Selecting the right species is crucial for optimal algae control.

The benefits of incorporating snails into your clean-up crew extend beyond mere algae consumption. When properly managed, snails have a minimal impact on water parameters. They efficiently convert algae into waste products that are easily processed by the aquarium’s biological filtration system. However, it is important to avoid overpopulation, as an excessive number of snails can lead to increased waste and potential imbalances in the aquarium ecosystem.

Recommended Snail Species for Algae Control: Selecting the Right Team

Choosing the right snail species for your goldfish tank depends on various factors, including the type of algae present, the size of the tank, and the overall compatibility with goldfish. Here are some recommended snail species and their specific attributes:

Nerite Snails: The Algae-Eating Powerhouses

Nerite snails are widely regarded as some of the most effective algae eaters in the aquarium hobby. They diligently graze on various types of algae, including green spot algae, brown algae (diatoms), and green hair algae.

Their relatively small size and peaceful nature make them ideal tankmates for goldfish. A significant advantage of Nerite snails is that they do not breed in freshwater aquariums, preventing the risk of a population explosion.

However, this also means that their numbers cannot be replenished naturally within the tank, so periodic additions may be necessary. It is important to note that Nerite snails may sometimes lay eggs on decorations or glass, which can be aesthetically displeasing, although the eggs will not hatch in freshwater.

Mystery Snails: The Gentle Giants

Mystery snails are larger than Nerite snails and possess a different approach to algae consumption. While they do consume algae, they are also opportunistic feeders and will readily accept leftover fish food and decaying plant matter.

This makes them useful for general tank cleaning. Their larger size means they produce more waste than smaller snails, so careful monitoring of water parameters is crucial.

Mystery snails can breed in freshwater, so it’s important to be mindful of the population. Their coloration can also add an aesthetic appeal. They come in a variety of colors, adding visual interest to your aquarium.

Ramshorn Snails: The Detritus Devourers

Ramshorn snails are smaller, disc-shaped snails that are effective at consuming algae and detritus. They can be particularly useful in planted tanks. They help remove decaying organic matter that can contribute to algae growth.

However, Ramshorn snails are notorious for their ability to reproduce rapidly in aquariums, especially when there is an abundance of food. This can lead to a population explosion, which can overwhelm the tank’s biological filtration and result in increased waste levels.

Careful monitoring of the population is essential. Implementing control measures such as reducing feeding and manually removing excess snails may be necessary to prevent them from becoming a nuisance. Despite their potential for overpopulation, Ramshorn snails can be beneficial in moderation. They contribute to a cleaner and more balanced aquarium ecosystem.

Maintaining a Balanced Aquarium Ecosystem for Algae Control: The Holistic Approach

While snails and other algae eaters can assist in keeping algae at bay, the most effective long-term strategy involves establishing a balanced and healthy aquarium ecosystem. This approach tackles the root causes of algae growth by managing nutrients, promoting beneficial bacteria, and creating an environment where algae struggles to thrive.

The Importance of the Nitrogen Cycle: Nature’s Filtration System

The nitrogen cycle is the cornerstone of a healthy aquarium. It’s a natural biological process that converts harmful waste products into less toxic substances.

This cycle starts with fish waste, decaying organic matter, and uneaten food, which release ammonia (NH3). Ammonia is highly toxic to fish and other aquatic life.

Beneficial bacteria then convert ammonia into nitrite (NO2), which is also toxic, albeit less so than ammonia. A second group of bacteria converts nitrite into nitrate (NO3), which is relatively less toxic.

Nitrate accumulates in the water over time. Regular water changes are essential to remove excess nitrate and maintain acceptable water quality. High nitrate levels can not only stress fish but also fuel algae growth.

Maintaining a healthy population of beneficial bacteria is crucial. This is best achieved through:

• Using established filter media.

• Avoiding over-cleaning the filter (clean only when flow is significantly reduced).

• Ensuring adequate oxygen levels in the water, as beneficial bacteria require oxygen to function.

Preventing ammonia and nitrite spikes is vital for the well-being of your goldfish and other tank inhabitants. Spikes can occur due to:

• Overfeeding.

• Overcrowding.

• Adding too many fish at once.

• Using medications that harm beneficial bacteria.

Regular testing of ammonia, nitrite, and nitrate levels using an aquarium test kit allows you to monitor the nitrogen cycle’s effectiveness and take corrective action if necessary.

Role of Plants in Nutrient Competition: Nature’s Sponges

Aquatic plants play a vital role in controlling algae growth by competing for nutrients, especially nitrates and phosphates.

Plants utilize these nutrients to grow, effectively depriving algae of the resources it needs to flourish. However, it’s crucial to select plant species that are suitable for a goldfish tank.

Goldfish are notorious for uprooting and eating plants. Tougher, less palatable plants are generally a better choice.

Here are some suitable options:

Anacharis (Egeria Densa)

Anacharis is a fast-growing plant that efficiently consumes nutrients from the water. It is relatively inexpensive and easy to propagate. Simply cut a stem and replant it in the substrate.

Anacharis is a great option for beginners, but it can grow quickly and may require regular trimming. Ensure adequate lighting is provided for optimal growth.

Java Fern (Microsorum Pteropus)

Java Fern is a hardy plant that doesn’t require planting in the substrate. It can be attached to rocks or driftwood using fishing line or super glue (gel type).

Java Fern is a slow-growing plant that tolerates a wide range of water conditions. It’s also not typically eaten by goldfish.

Anubias

Anubias is another slow-growing, hardy plant that is suitable for goldfish tanks. Like Java Fern, it should be attached to rocks or driftwood rather than planted in the substrate, as burying the rhizome can cause it to rot.

Anubias is available in various sizes and leaf shapes, adding visual interest to your aquarium. It prefers low to moderate lighting.

Implementing Effective Algae Control Methods: Proactive Management

Beyond the nitrogen cycle and aquatic plants, several other methods can be employed to proactively manage algae growth.

Regular Water Changes

Water changes are essential for removing excess nitrates and other pollutants from the aquarium. A general recommendation is to perform a 25% water change weekly.

However, the frequency and volume of water changes may need to be adjusted depending on the bioload of the tank (the amount of waste produced by the fish), the density of plants, and the results of water testing.

Always use dechlorinated water that is the same temperature as the aquarium water to avoid shocking the fish.

Proper Filtration

A well-maintained filter is critical for removing particulate matter, dissolved pollutants, and establishing a healthy population of beneficial bacteria.

Aquarium filters typically utilize three types of filtration:

• Mechanical Filtration: Removes debris such as uneaten food and fish waste.

• Chemical Filtration: Removes dissolved pollutants such as chlorine, chloramine, and medications. Activated carbon is a common chemical filtration media.

• Biological Filtration: Provides a surface area for beneficial bacteria to colonize and convert ammonia and nitrite into nitrate.

Manual Algae Removal

Manually removing algae is an important part of maintaining a clean aquarium.

• Use a soft brush or algae pad to gently scrub algae off of decorations and the substrate.

• An algae scraper can be used to remove algae from the glass. Be careful not to scratch the glass.

• Consider using a magnetic algae cleaner for ease of use.

By combining these strategies, you can create a balanced and thriving aquarium ecosystem where algae growth is minimized, and your goldfish can flourish.

Tools and Products for Managing Algae: Your Algae-Fighting Arsenal

While maintaining a balanced ecosystem is paramount, aquarium keepers often require additional tools and products to manage algae effectively. Understanding the purpose and proper usage of these resources is critical for maintaining a healthy and aesthetically pleasing aquarium. This section outlines the tools and products available for monitoring water quality, controlling algae, and maintaining a healthy environment.

Aquarium Test Kits: Monitoring Water Quality Parameters

Regularly testing your aquarium water is essential for understanding the health of your tank. By monitoring key parameters, you can identify potential problems before they escalate and negatively impact your fish and plants.

Testing allows for proactive adjustments to be made. It ensures a stable and thriving environment.

The Importance of Testing Ammonia, Nitrite, Nitrate, and pH

Ammonia and nitrite are highly toxic to fish, even in small concentrations. Their presence indicates an imbalance in the nitrogen cycle. Nitrate, while less toxic, can contribute to algae growth and stress fish at elevated levels.

pH affects the solubility of many substances in the water. It can influence the toxicity of ammonia and the overall health of aquatic life. Regular testing allows you to track these crucial parameters and identify any deviations from the ideal range for your specific aquarium inhabitants.

Selecting the Right Test Kit: Liquid vs. Strips

Aquarium test kits are available in two primary forms: liquid test kits and test strips.

Liquid test kits generally offer greater accuracy and reliability compared to test strips. They involve adding specific reagents to a water sample and comparing the resulting color change to a reference chart.

While this method is more time-consuming, the increased accuracy makes it ideal for serious aquarists and situations where precise measurements are critical.

Test strips, on the other hand, are convenient and easy to use. Simply dip a strip into the water and compare the color changes to a chart.

However, test strips tend to be less accurate and may provide only a general indication of water quality parameters. For beginners or for routine checks, test strips may be sufficient.

Consider liquid tests for critical analysis and strips for basic monitoring.

Algaecides: Use and Precautions

Algaecides are chemical treatments designed to kill or inhibit algae growth. While they can provide a quick fix for severe algae blooms, they should be used with caution and only as a last resort.

Overview of Algaecide Types

A variety of algaecides are available on the market, each with different active ingredients and target algae types. Some algaecides are broad-spectrum, while others are specifically formulated for certain algae like black beard algae (BBA) or green water algae.

It is important to research the specific type of algae you are dealing with. Then choose an algaecide that is effective against that type while being safe for your fish and plants.

Risks Associated with Algaecide Use

Algaecides can pose several risks to your aquarium ecosystem. Many algaecides can be toxic to fish and invertebrates, especially when used improperly or in excessive amounts.

They can also disrupt the biological filter. This can kill beneficial bacteria that are essential for maintaining the nitrogen cycle.

Additionally, the rapid die-off of algae following algaecide treatment can release large amounts of organic matter into the water. This can lead to ammonia spikes and further water quality problems.

Algaecides as a Last Resort

Due to the potential risks, algaecides should only be considered after all other algae control methods have been exhausted. This includes addressing the underlying causes of algae growth, such as excess nutrients, inadequate lighting, and poor water circulation.

Before using an algaecide, perform a large water change to reduce nutrient levels. Closely monitor your water parameters after treatment to ensure that ammonia and nitrite levels remain within safe limits.

Other Essential Tools for Algae Control: Rounding Out the Toolkit

Beyond test kits and algaecides, several other tools can aid in algae management.

Water Conditioners: Neutralizing Harmful Substances

Water conditioners are essential for neutralizing chlorine and chloramine, chemicals commonly found in tap water that are toxic to fish and beneficial bacteria. They also often contain ingredients that help detoxify heavy metals and promote the healing of fish skin.

Always use a water conditioner when adding new water to your aquarium. This ensures a safe and healthy environment for your aquatic inhabitants.

Siphons: Efficient Waste Removal

A siphon is a simple but effective tool for removing debris from the substrate and performing water changes. The siphon works by creating a vacuum that draws water and debris up through a tube.

This allows you to remove accumulated waste, uneaten food, and algae from the bottom of the tank. It also helps to prevent the build-up of harmful substances that can contribute to algae growth.

Filters: Maintaining Water Clarity

The filter is a cornerstone of any healthy aquarium. Filters remove particulate matter, dissolved pollutants, and excess nutrients from the water.

Mechanical filtration removes suspended particles like uneaten food and debris. Chemical filtration removes dissolved pollutants like ammonia and nitrite. Biological filtration supports the growth of beneficial bacteria that break down harmful substances.

When selecting a filter, consider the flow rate and media capacity. Ensure it is appropriate for the size of your aquarium and the bioload of your fish.

Aquarium Lights: Balancing Act

Aquarium lights provide the necessary illumination for plant growth and enhance the visual appeal of your tank. However, excessive or inappropriate lighting can also contribute to algae growth.

Select a light with the appropriate spectrum and intensity for your plants. Use a timer to maintain a consistent lighting schedule. This prevents overexposure and minimizes the risk of algae blooms.

Best Practices for Preventing Algae Growth: A Preventative Strike

While maintaining a balanced ecosystem is paramount, aquarium keepers often require additional tools and products to manage algae effectively. Understanding the purpose and proper usage of these resources is critical for maintaining a healthy and aesthetically pleasing aquarium. This section emphasizes the proactive measures that can be adopted to minimize algae growth. Focusing on lighting, feeding practices, and consistent tank maintenance, this section provides a framework for sustained algae prevention.

Balancing Aquarium Lighting: Finding the Sweet Spot

Aquarium lighting plays a pivotal role in algae proliferation. While light is essential for plant growth, excessive or imbalanced lighting can trigger significant algae blooms. The key is to find a balance that supports plant health without inadvertently fueling unwanted algae growth.

Adjusting Light Duration and Intensity

Careful adjustment of both the duration and intensity of aquarium lighting is crucial. Start by limiting the light duration to approximately 8-10 hours per day. Observe the tank closely for any signs of algae growth and adjust accordingly.

Reducing the intensity can also be beneficial, especially if dealing with persistent algae issues. Consider using dimmer switches or reducing the number of light fixtures if possible.

The Benefits of Timers

Consistency is paramount when it comes to aquarium lighting. Implementing timers to regulate lighting schedules is an invaluable strategy. Timers ensure that the aquarium receives a consistent amount of light each day, minimizing fluctuations that can stress fish and promote algae growth. Consistent light cycles can also help regulate plant growth and nutrient uptake, further preventing algae.

Proper Feeding Habits: Minimizing Waste

Overfeeding is a significant contributor to algae blooms. Uneaten food decomposes, releasing nutrients like nitrates and phosphates into the water, which then act as fertilizer for algae. Implementing careful feeding habits is crucial for mitigating this issue.

Selecting High-Quality Fish Food

The choice of fish food can significantly impact water quality. Opt for high-quality fish food that is easily digestible. These foods are formulated to maximize nutrient absorption, minimizing the amount of waste produced by the fish. Look for formulations that contain lower levels of phosphates, which are a known algae fuel.

Avoiding Overfeeding

One of the simplest yet most effective ways to prevent algae growth is to avoid overfeeding. Feed your goldfish only what they can consume within a few minutes. Observe their feeding habits closely, and adjust the portion sizes accordingly. Regularly remove any uneaten food to prevent decomposition and nutrient buildup.

Regular Tank Maintenance: Consistency is Key

Consistent tank maintenance is indispensable for preventing algae growth and maintaining a healthy aquarium ecosystem. Regular water changes and thorough cleaning remove excess nutrients and debris, creating an environment less conducive to algae proliferation.

Performing Routine Water Changes

Routine water changes are fundamental to aquarium health. Regular water changes help to dilute nitrates and other pollutants, preventing them from reaching levels that can trigger algae blooms. Aim to perform water changes of 25-50% every one to two weeks.

Cleaning Substrate and Decorations

In addition to water changes, cleaning the substrate and decorations is essential. Use a gravel vacuum to remove accumulated debris from the substrate.

Algae often grows on decorations, so gently scrub them with a soft brush or algae pad during water changes. Regularly cleaning these surfaces removes algae and prevents it from spreading throughout the tank.

So, while do goldfish eat algae, relying on them as your sole algae control method isn’t the best strategy. A balanced approach involving regular tank maintenance, proper lighting, and maybe some dedicated algae eaters will keep your goldfish happy and their home sparkling clean. Happy fishkeeping!
