Is Microfauna Good For Aquariums or Not?

Microfauna are tiny creatures that live in aquariums, such as little worms, tiny shrimp, and small snails. These small animals can be very helpful for keeping the aquarium healthy and clean. They eat leftover food and waste, which helps reduce harmful substances in the water. Microfauna also provides food for fish and other animals in the tank. In addition to keeping the tank clean, they add diversity to the ecosystem. Overall, having microfauna in an aquarium can be a good choice for both the fish and the water quality.

What is Microfauna?

Microfauna are tiny living things, often so small you need a microscope to see them. They live in different places like soil, freshwater, and oceans. 

These small creatures include tiny protozoa, bacteria, and small invertebrates like rotifers and nematodes. 

Even though they are small, microfauna are very important for recycling nutrients, breaking down dead things, and being part of the food chain. 

In water, microfauna help keep ecosystems healthy by breaking down organic matter, making sediments airy, and providing food for larger creatures. Having them around boosts biodiversity and helps keep the ecosystem balanced.

Benefits of Microfauna in Aquariums

Benefit 1: Keeping Water Clean 

Microfauna are tiny creatures that help keep the aquarium healthy by eating leftover food and waste. This helps make the water cleaner, which is better for fish and plants.

Benefit 2: Increasing Variety 

Having microfauna adds different types of life to the aquarium. This variety is important for making a balanced home for many living things and helps the tank handle changes better.

Benefit 3: Giving Food Options 

Many fish and sea animals depend on microfauna for food. Tiny shrimp, worms, and other microfauna are tasty snacks for bigger fish, helping them grow strong and stay healthy.

Benefit 4: Helping Nutrients Go Around 

Microfauna helps recycle nutrients by breaking down old plant and fish matter. This process not only makes nutrients available for plants but also keeps the bottom of the tank aerated, which is good for the tank’s health.

Benefit 5: Helping Good Bacteria Grow 

Microfauna can help good bacteria thrive in the aquarium. These bacteria are important for the nitrogen cycle, changing harmful ammonia into safer substances, which leads to a healthier aquatic environment.

Disadvantages of Microfauna in Aquariums

Disadvantage 1: Overpopulation Risks 

Microfauna are helpful in small amounts, but they can grow very quickly if conditions are good. When they overpopulate, they can upset the balance in the aquarium, using up resources and possibly hurting larger fish and plants.

Disadvantage 2: Competing for Resources 

Microfauna can fight with fish and plants for food and nutrients, especially in smaller tanks. This struggle can make it harder for the more noticeable aquatic life to grow and stay healthy.

Disadvantage 3: Releasing Harmful Byproducts 

Sometimes, certain microfauna can create harmful waste when they break down organic matter. If not watched closely, these waste products can lower water quality and hurt the whole ecosystem.

Disadvantage 4: Difficulties in Control 

For aquarium owners, controlling microfauna populations can be hard. If their numbers get too high or too hard to manage, it may take a lot of effort to bring things back to normal, including changing feeding habits or adding predatory species.

Disadvantage 5: Introducing Pests or Diseases 

Some microfauna might carry pests or diseases that can harm fish and plants in the aquarium. It is important to make sure that any microfauna introduced are free from harmful germs to keep a healthy aquatic environment.

How to Add Microfauna into an Aquarium

Step 1: Choose the Right Microfauna

Research and pick the right types of microfauna for your aquarium. Common choices are brine shrimp, copepods, and amphipods. Make sure they can live well with your current fish and plants. 

Step 2: Get the Aquarium Ready 

Make sure your aquarium is set up with good water conditions (temperature, pH, salinity), and that it is free from harmful chemicals or medicines that could hurt the tiny creatures. 

Step 3: Get Microfauna

Buy your microfauna from a good source, like an aquarium store or a trusted online store. Look for healthy, live creatures, and avoid buying from places that seem shady. 

Step 4: Help Microfauna Adjust 

Before adding tiny creatures, help them adjust to your aquarium conditions. You can do this by slowly adding aquarium water to the container where the microfauna are kept for a couple of hours. Start with small amounts and slowly add more aquarium water. 

Step 5: Add Microfauna to the Tank 

Gently put the adjusted microfauna into your aquarium. It’s best to do this when the lights are low or off to help reduce stress on the creatures. 

Step 6: Check Water Conditions 

After adding the tiny creatures, regularly check the water conditions to make sure they stay stable and good for both the microfauna and your other fish and plants. 

Step 7: Watch the Balance 

Keep an eye on how many microfauna you have as well as your fish and plants. Make changes if needed, like adjusting how much you feed them to make sure there’s enough food without causing too many microfauna to grow. 

Step 8: Keep Taking Care of the Aquarium 

Continue to take care of your aquarium regularly, including changing the water and looking for any signs of problems or stress among the fish and tiny creatures. Regularly watching will help you make sure the microfauna do well without harming the ecosystem.

What is the Diet of Microfauna?

Microfauna are tiny creatures that eat different things based on their type and where they live. They usually eat organic matter, which includes decaying plants, tiny bits of dirt, and small organisms like algae and bacteria. Some microfauna, like copepods, eat phytoplankton, which are tiny plants floating in the water, while others might eat zooplankton or even smaller microfauna. This eating habit is important because it helps break down waste and recycle nutrients back into the environment, which helps plants and bigger water animals grow.

Differences Between Microfauna and Meiofauna

Microfauna and meiofauna are both important parts of aquatic ecosystems, but they are very different in size, where they live, and what they do. Microfauna are usually organisms smaller than 0.1 mm, like tiny bacteria, protozoa, and small crustaceans. 

They help with nutrient cycling and breaking down organic matter. On the other hand, meiofauna are a bit bigger, usually between 0.1 mm and 1 mm, and include nematodes, copepods, and other small invertebrates. 

Meiofauna often live in the sediments of aquatic environments and help keep ecosystems healthy by breaking down organic matter and serving as food for larger animals. While microfauna thrive in the water column and surface layers, meiofauna are more connected to the bottom, showing their different homes and roles in the aquatic ecosystem.

Conclusion

Microfauna can be very good for aquariums if managed well. They help create a healthy environment by breaking down waste and supporting good bacteria that are important for fish and plants. However, when too many microfauna are in the tank, they can cause problems. They may compete with larger fish and plants for food or even release harmful waste. To enjoy the benefits of microfauna, aquarium owners need to keep an eye on their numbers and make sure their aquarium stays balanced.

FAQ’s

1. What is the best way to add microfauna to my aquarium? 

To add tiny creatures, first, pick types that will do well in your aquarium’s setup. Gradually mix their water with your aquarium water over a few hours to help them adjust, then gently put them in the tank when the lights are low to keep them calm. 

2. How can I tell if I have too many tiny creatures? 

If you have too many tiny creatures, you might see poor water quality, shown by higher levels of ammonia or nitrites, and your fish and plants may start to look unhealthy. Checking regularly will help you keep their numbers in check. 

3. Are there any microfauna I should not put in my aquarium? 

Yes, you should avoid adding microfauna that can carry pests or diseases, as these can hurt your fish and plants. Always get your microfauna from trustworthy sellers who ensure they are healthy and clean. 

4. How often should I change the water in an aquarium with tiny creatures? 

Changing the water regularly is important for a healthy aquarium. It’s usually best to change 10-20% of the water every week, but depending on how many microfauna you have and the tank’s overall health, you may need to change it more or less often to keep things balanced and clean.
