All types of fishes amazingly survive when they surf in a natural reservoir, like a pond, lake, etc. But when we start petting them, the problems start occurring.

Why Is My Fish Body Bent

Reasons Behind Body Bend

Here is a short list of most likely reasons that can cause the body to bend a fish.

By Born Deformation

When we pet fish and let them breed, we often see that all the fish fries are not the same. Some fries are bigger than others, and some look so juvenile.

Again, some of those do not catch the color from their parents at all. Similar to the cases, some fries may be born with a curved spine.

The significant part of this is we can notice the deformation in the fries, and we can not form it as a disease. Instead, it is the body shape they have in their genes. However, there is no treatment behind this and 2 fries in 100 can be like this.

Infection By Bacteria

The water we use is not the water we can find in natural reservoirs. In a lake or pond, with all the harmful bacteria, beneficial bacterias exist. As a result, all the fishes get adequate antidotes against their inconvenience.

Infection By Bacteria

But in an aquarium or small artificial pond, we need to provide water conditioners and beneficial bacteria.

However, the prime reason behind this curved body is an infection. It can be either in the spine directly or in the organs, and the reason is Gram-positive mycobacteria.

These mycobacteria infect the fish body if the water condition is not favorable for the fish. As a result, the body starts bending.

The bending process is not done overnight. It is a slow process and takes place for a significant duration. Without a proper set of treatments, it continues and curves a moon-like curve.

Symptoms

There are several symptoms you will notice when your fish gets infected. Ther significant symptoms are

  1. Lethargy,
  2. Emaciation,
  3. Fin and scale loss,
  4. Exophthalmia,
  5. Skin inflammation and ulceration,

  8. Nodules in muscles
Treatment For Bent Fish

If you find the symptoms in your fish, start treating them carefully. Follow the steps to cure your fish.

  1. If a fish is infected, other fishes are more likely to be contaminated too. So, determine all the infected fishes first.
  2. After that, prepare a tank according to the number of fish by providing conditioned water.
  3. With a net, pick all the infected fishes from your tank and put them into the newly prepared tank.
  4. Now use Streptomycin for four days in the water. The dose is 10.6 mg per liter or 40 mg per gallon.
  5. On the fifth day, use Rifampin with the food of those fishes. You have to continue this for two months; if needed, the dose can be higher. And the optimal amount is 10 mg in 100 grams.
  6. The last treat that will last for four months is the use of Isoniazid. The dose is 10.6 mg per liter, similar to Streptomycin. Mix the Isoniazid from the first day of the fish’s quarantine period.

After 4 to 5 months, you will notice that your infected fishes become healthier and eventually cured.
