What's a good freshwater fish that eats waste?

Question

Anyone know?

Answer 1

Fish don't eat fish waste-- there is little or no nutritional value in it, as all useful materials have already been extracted.  Many fish will eat extra food on the bottom, and some will eat algae (though generally not effectively), but the most effective way to remove waste is still by siphoning the gravel-- not only does it remove waste, but by removing water, it will also remove nitrogenous compounds from the water before they damage the fish.

Answer 2

no fish eats pee and p**p!!!! would you like to live on other fish's pee and p**p!?

Answer 3

No fish that I know of will eat waste as in rotted food or fish waste. Most shrimp will, Amano shrimp are good for eating waste and algae. Snails as well.

Answer 4

If you want a freshwater fish that will eat algae and food remnants, go for an algae eater (pleco) or a cory cat fish. However, neither will eat fish p**p.

Be warned plecos look small but they grow immensly. I have one in my 20 gallon who's 3 years old and he's grown about 4 inches from the time I got him.
