I have had a Green Open Brain for over a year now. This past week it has stopped opening up during the day and has become very hard. I was wondering what the life span is for a brain or do I need to look at other factors?
alk is a bit low, but shouldnt cause any problem. see if it opens back up in a few days. what other corals do u hv? changing 10% water wouldnt be a bad idea either.
I have had red mushrooms, zoe's, xenia's, and a torch for as long as I have had the brain. I also have star polyps, hammer, a toadstool leather, and a hairy mushroom. I just added a colt, elephant ear and some kenia trees.
