Who could be the culprit??

[I<3fish]

Larger pictus for sure. They are known to be aggressive towards each other. They will attack each other even though they are a schooling catfish, you need a large school for it to work well (5+.)

I don't want that many so I have one and he is perfectly content not having to fight over food.

3 Pictus cat's is not an OK size school, it's fairly small.

ok yeah i thought three was alright but thats what i was thinking was that the larger one was the most likely culprit, i will definitely go out and get a couple more and that should help
