Do any fish eat fish waste?

[redtailcatfreak]

I picked mine up from a guy who was selling a tank and i just wanted the fish. But I work at Petsupermarket and we got some small ones in last week. Youll just have to go around to your LFS and look for them. I love these guys but they dig trenches around the sides of the tank and flatten all the sand out. Every waterchange i have to remake all the hills and burry plants. Hahahaha

for me, all the fish waste ends up either in the filter sock, or in the two back corners of my tank. It takes me all of a minute to gravel vac all of it.

I have an earth eater in a smaller tank right till it gets bigger. I had a pearl cichlid but it died or got killed recently. There wasn't enough left to figure out what happened to him. My green Texas cichlid did chase him around some before then though.

I had a bichir which use eat the waste from my dat's..

I've found that by having good water movement with a sand substrate will keep the waste suspended long enough for the filters to remove it so your mech filtration can take care of it all.

There isn't any fish that will eat waste. It wouldn't matter anyway, because what goes in still has to come out the other end. The end result will always be poop. Don't be lazy and do water changes.

Detritivores, also known as detrivores or detritus feeders, are fish that eat detritus. (decomposing organic material) To which there are numerous species of fish that fall into this category, both marine, and freshwater species. Semaprochilodus taeniurus (Fei Feng) have been known to recycle others fishes waste.

But as stated, they too excrete waste, so that probably won't resolve your issue.

Those guys are sand-sifters, but they eat mostly decomposing organisms, not fish turds. I'd think that feces contains mainly things that cant be used as nutrients, and that's why it's discarded.

I've watched "those guys" eat turds, whch is part of what a detritivore does, they eat detritus.

In biology, detritus is non-living particulate organic material (as opposed to dissolved organic material). It typically includes the bodies or fragments of dead organisms as well as fecal material.
