My arowana has been jumping out of its tank a couple of times since I bought it. Is that a sign of stress? if so, what can I do to reduce it? I already check for pH, water clarity, and temperature. I turn the lights off for a while, but now it's on a normal on/off cycle. Maybe it's just adjust to the new tank or something... Its appetite is rather low too. It will only eat when it really needs to. Unlike my other fish, which will eat until they explode.
???? they see daylight and go....its just there nature
