A few weeks ago I was given about 100 lbs live rock from a reef tank that had been in the dark for about 4 months. Lights burnt up and owner never replaced. (was waiting for everything to die) Tank was offered for free if you take it down. Long story short I took it down added rock to my tank. tons of mushrooms, sponges, and other fauna popped up in a few days. While moving it around in my tank I found a small colony of Zoanthids hiding in a cave. They are pure white, how long till they color up again?
