Similar to the red belly pacu?
Hello so I have a 120 gallon fish tank, and for a while I just had simple catfishes such as eclipse and pictus and some other fish. But recently I decided to give the red belly pacu a try and to my surprise I really enjoyed having him. The reason I enjoyed him so much is because he eats everything! The other day I put a crab in there and he ate the whole thing shell and all. So my question to all of you is what other fish has this type of behavior? Something that will eat feeder fish, crab, pellets, flakes just like my red belly pacu... any information would be greatly appreciated thank you.
