What's up guys? I have a green open brain and it has barely been opening for about a week now. All my levels are good, all my other corals are rocking, but the brain just isn't swolling up like it normally does. I wouldn't normally be worried except this guy usualy get two to three times it's normal size when the lights are on. Nobody is nibbling on it that, I can tell anyway. My purple tang was about a 6 weeks ago so I got rid of him. Other than that he looks fine, he has good color and last night I fed mysis about an hour after the halides went out and the brains mouths opened up. I didn't see any arms grabbing food or anything, but the mouths were closed and with in a minute of feeding the mouths opened up. Anyway, I'm not sure why he isn't opening. Anyone have any ideas?
