Tips On How To Treat Clamped Fins In Betta Fish

1. Change the Water Right Away

One of the more common issues with a betta fish clamping its fins has to do with the water quality.

If the water quality has depreciated, the betta fish will begin to act oddly. This can include not eating, refusing to swim in specific parts of the aquarium, and/or clamping its fins.

If you notice a lethargic betta fish with clamped fins then it is likely this problem. The betta fish might not like its environment and is starting to find it difficult to swim around.

When this happens, you are going to want to change the fish tank’s water as soon as possible. It is also smart to look at what caused the drop in water quality to fix the problem for good.

2. Look for an Infection

It is possible to look for a good betta fish clamped fins treatment by assessing a possible infection.

Some betta fish will start clamping their fins as a response to an underlying infection. When this happens, you are going to want to find a clamped fins treatment that is easy to apply and will work immediately.

A good example of this would be adding a tablespoon of aquarium salt per gallon of water in the fish tank.

This should help the betta fish recover from its infection if that is the underlying problem.

3. Feed Small Amounts of Food

During this period, you will want to feed the betta fish with clamped fins a good amount of fish food.

The idea is to keep them healthy and happy in the fish tank. This is not going to happen if you are not careful about what you’re doing.

The goal is to make sure the betta fish doesn’t stop eating. When that happens, it becomes a lot harder to keep the betta fish happy and willing to swim.

Take the time to use quality betta fish food for clamped fins. This will go a long way in appealing to the betta fish and allowing it to open up.

4. Reduce Noise Around The Fish Tank

Some betta fish will get nervous due to external conditions.

This is often something fish tank owners don’t think about. You will naturally assume the problem has to do with something the fish is interacting with such as food or the water. While this is possible, there are external issues that can arise.

Sound is one of them.

If it is too loud around the fish tank, those vibrations are going to shake the fish tank. The betta fish will feel those vibrations and become nervous.

This can lead to the betta fish clamping its fins.
