I have two ocellaris in my reef tank that have been there for about a year. I have been trying to breed them with no success. I recently heard that some clowns will breed if they are given half a clay pot to lay on. I put one in about four months ago and they seem happy but there still hasn't been any spawning. Does anyone know what to do to make my ocellaris breed? By the way its a 29 with a 13 hour photoperiod and the nitrate, nitrite, ph, alkalinity and everything else except phosphate is under control. I am trying to get rid of it with phosban which I just added. If anyone has a suggestion about that it would help too. There is brown algae all over the bottom that I keep trying to remove.
