How long does it take typically for a new frag of cyphastrea to show its polyps? I started off under the advice that it would be fine high up in the 30G tank under a 20K 150W mh but after a couple days of no polyps showing and the sky blue starting to brown out, I relocated it towards the bottom. It looks better over the past few days than it has but there has yet to be polyps extended out. Any experience?
