I suppose I just have an affinity for piranhas. Mine spends much of it's time hiding (or lurking) behind a piece of driftwood, usually venturing out later in the day to feed, explore, "glass surf", or what have you. At a later date, I'd like to set up another tank as a cichlid tank, possibly a parachromis motaguensis.I don't think it's a lack of respect. people think they're getting an aggressive, active fish. Most rhoms just sit in the corner and they get bored with them.
