Video: Swim Bladder Disease
If your fish only swims on the surface, belly up, or has difficulty rising from the bottom, then it has swimming problems. Swimming problems can be caused by a variety of reasons, for example, various diseases (bacterial, viral, fungal, parasitic, cancer), starvation, general weakness, diseases of the fins, swim bladder, excessive gas production in the gastrointestinal tract. Ornamental round-bodied fish of the crucian family especially suffer from overturning.
Diseases associated with the swim bladder. Rolling over is very often associated with diseases of the swim bladder, which is responsible for buoyancy. In goldfish and other cousins, there is a direct connection between the esophagus and swim bladder, which allows air to escape through the digestive tract.
Sometimes problems with the swim bladder are due to the fact that it is squeezed by the food eaten. Viruses and bacteria also lead to inflammation, preventing air from entering and exiting the bladder freely. Feeding with a dry ball causes the food to absorb water like a sponge and expand inside the fish, causing the bladder to squeeze.
What to look for. If your fish develops this syndrome, you will find it difficult to swim. You should pay attention to the following signs:
1. Swimming on the surface of the water, sometimes belly up.
2. Difficulty climbing from the bottom to the surface.
3. The fish swims with difficulty on the bottom of the aquarium.
This condition may be temporary or permanent, but most fish remain alert and appetite-free. The disease is not contagious.
Treatment. Unfortunately, there are no known 100% effective medical and surgical procedures that could cope with inversion in aquarium fish.
However, there is one method that often helps. You can give a sick fish a green pea (canned, boiled and slightly crushed) once a day. Exactly how the green pea works is unknown, but it may help to move light and / or air-filled food through the digestive tract.
The green pea treatment involves raising the aquarium water to 24-27 ° C and feeding it with sinking commercial dry food. Do not feed sick fish with dry plates or balls.
Enemies and Diseases of Goldfish
In order to prevent problems with swimming, the following measures should be taken:
- When buying new fish at the pet store, choose those that swim normally in the aquarium.
- Isolate any new fish for one month before introducing them to your aquarium.
- If you keep round-bodied goldfish in your aquarium, feed them sinking dry food and add some green vegetables to their diet, including canned or fresh peas.
