age old question.....why wont my sun coral open. EVERYTHING else in the tank is happy and growing great, sps, lps, zoas, all of it. my tank is well established (2years) and i have kept one in the past that did very well until an extended outage in my tank while i was away. i've tried the bottle trick and i'm trying to feed mysis or brine shrimp. if anyone has any suggestions feel free.
