Hi so I have a reefer 900 195 gallons and is 79 inches long my question is can I put 2 more clown fish in my tank? I already have 2 clowns in the tank and a nem they do not go into the nem it has been like this for about a year no interest in it. I was thinking if I can get the 2 new clowns to host the nem will the clowns be fine together or will they attack? (They are Ocellaris clowns)
