How to keep fish alive in a small fish tank

Keeping fish requires some basic preparation and precautions, whether it is a small or large fish tank. Here are some suggestions:

1. Establish a nitrogen cycle

Before raising fish, you need to understand the nitrogen cycle. This refers to converting fish waste into nutrients that plants can use. Usually when setting up a fish tank, there is a certain nitrogen cycle time. This can be accomplished by adding bacteria and other microorganisms to the water.

2. Keep water clean

Regularly changing the water, cleaning the fish tank and replacing the filter material are very important to maintain water quality. You’ll also want to test the water quality to make sure parameters like pH, ammonia, and nitrates are within the appropriate ranges.

3. Choose the right type of fish

In a small fish tank, you need to make sure you choose fish that are suitable for living in a small space. In addition, it is best to choose some species that are easy to care for, such as freshwater fish, such as open fish, surgeonfish, etc. These fish not only have lower water quality requirements, but are also relatively easy to care for.

4. Breeding environment

Make sure there are enough hiding places and swimming space in the tank, as well as appropriate decoration and aquatic plants. These can simulate the fish's natural habitat and provide a suitable environment for growth.

5. Reasonable feed

Pay attention to feeding the right amount of feed and not overfeeding. Each type of fish has different food needs, so you need to understand your fish's eating habits and provide the right food.

6. Temperature control

Water temperature needs to be maintained within a suitable range, which is crucial for the survival of fish. Different types of fish have different temperature range requirements, so the water temperature needs to be adjusted according to the fish being raised.

7. Regular inspection

Regularly checking the health of the fish, possible signs of disease, water quality, whether the filter and heating system are normal, etc. are important measures to ensure the health of the fish in the fish tank.

The most important thing is to have a clear understanding of the fish's sensitivity and water quality requirements. Before raising fish, it is best to do some homework to understand the living habits of the fish you want to raise, so that you can better provide them with a suitable living environment.
