one of my senegals is a little nippy towards the other one i have right now. not so much that he's constantly being harassed or anything its just been the occasional "pretend" nip when it comes across the other sometimes. my guess might be that they are growing so fast and i havent gotten my 55 gallon up and running for them yet so it feels kinda cramped in a 10 gallon with a second sen and a delhezi - which i just moved to a qt tank tonight. any thoughts on this? they were getting along pretty well for a while. when they first got aclimated to each other there was the typical 2 days of chasing but after that they were pretty much fine with each other. does this sound like it might be one of those with an overly aggressive attitude or is this normal or will it just fade out when they get into a bigger tank?
