My understanding is that cetopsis sp tend to feed on larger fish, and was wondering if this has been anyone's experience. I have a hemiarius stormii, a jaguar catfish, a marble lancer and a wertheimeria maculata. They are all at least 4 inches in length while the cetopsis parma I'm interested in is around 2 inches. Would they likely get bitten by the cetopsis or is this a relatively safe setup?
