If it’s a male the chances are it’ll chase the other plecs, it may kill them. I currently have a female blue eye that doesn’t bother with my typhoons, she’s very placid. The male blue eye I had previously was nuts.
Were yours specifically Suttoni/Suttonorum? I have a Cochliodon who it a bit of a bully who is a bit aggressive but has never done any real damage.
I'm trying to figure out if BES is more aggressive than BEC or if it boils down to individual fish/environment/ect.
