Fish poop is scientifically called "feces" or "excrement." It is the waste material produced by the digestive system of fish and contains undigested food particles and other waste products.
It does what other fish do, swim, eat, poop, pee, die.

Fish don't poop out of their stomach. They poop out of their anus just like all vertibrates. Fish injest food, digest it in the stomach and intestine, and then egest it out the anus.
