I've had a maroon clown for about 7 months now and its about two inches. I just got another smaller one that's about one inch on Tuesday. They kept fighting with each other and the small one just hides behind one of the drains all day. Today the small one just lays on the bottom of the aquarium and I haven't got him to eat anything yet. I put him a net so I could get him to eat but he's just laying on the bottom of that too. What can I do to help him? I think he is going to die soon.
