I've had this coral, still not sure what he is, for about 3 months. He seems to be doing well eexcept for this growth. Is he growing, splitting, or not doing as well as I think he is? Tank specs : sg 1.023 pH 8.3 ammonia nitrate and nitrite all 0 calcium is too high for my test to read. I am doing 2 5 gal water changes a week to help with the calcium levels. The tank is a 65 gal tall with a 30 gal fuge. Any ideas??
