My 30cm oscar may not be happy and i was wondering if i could get some advise off fellow oscar owners.
Tank = 6x2x2
Other fish = vieja and another smaller oscar
Bullied ? = he doesnt get picked on.
So my oscar is camped at the bottom of the tank and not swimming about, the other fish seem fine and if i put food into the tank he will come up and eat it. Not with the same zeal as he would previously though.
