My fish stay in the bottom of the fish tank and doesn't have intentions to be swimming, I'm scared because it been three days now I don't know what to do.....
Hello:
If that happens it is because some factor it is not appropriate. It may be that the water is not cleaned or that the fish tank is too small, or that there are more fish than the account for the space of the tank.
It is possible that the fish ate too much, or that the blood worm had some bacteria.
Also, it is important to clean any leftovers of blood worm from the water.
To help him clean his guts, you can cook some peas and give him small pieces of it.
All the best,
