I bought 5 pictus catfish hoping theyd be a nice addition to my 125 CA cichlid tank but they have been some what of a disappointment. Every where I read says they are a shoaling fish and that they love to swim together but mine just stick to their own little territories. If ones crosses into another's spot then there is a lot of tail slapping and face to face confrontation with their wiskers pointed straight up, which actually looks cool. It reminds me of bettas when they flare up. Should I buy more or is this a some what normal behavior?
