I am Calm, I just want the OP to not be frightened off because majority of the people here (cichlid subforum is the worst for this and also where he will inevitably end up) will tend to list recommended size as MINIMUM. a well cared for oscar in a 3' tank would be a happy fish, sure he would be better with more space but he would be far better off than a lot of the idiots who keep them in 20g and wonder why they dieno where in this thread is there " OMG BIGGER TANK" most responses said its fine for now but ideally would be bigger..calm down![]()
