do fish pee?

Answer 1

yes they do. actually i remember once catching a sunfish, which "extracted vengance" by peeing in my face!

Answer 2

Freshwater fish do, because they have to maintain their salt balance. If they didn't pee almost all the time, their bodies would swell from water coming in. Fish have a higher concentration of salt inside their cells, but water wants to dilute it to the same concentration of salt from their enviroment. This is what happens when a fish gets dropsy - for whatever reason (tumor, kidney disease, reaction to medications) their kidneys can't get rid of the pee, so the excess water causes them to swell up so much their scales stick out like a pinecone and the eyes and abdomen to bulge out: http://www.fishpondinfo.com/photos/fish/barbs/barb2.jpg , http://www.petsolutions.com/images/dropsy.jpg

No they poop like chickens, but believe it or not they drown. Those fishes that die and stay in the ground is because their lungs are fill with water.
