marrone don't know have it about 3 weeks and Thursday it look like it was started to lose it colors ,and this moring it look like it was going to blow up
I know these type brain coral invert their stomach and blow out like that at night, similar to my avatr, but they usually go back once the light come on. Have you tried to feed it some thing?
Frank, keep a close eye on it. My brain did the same thing a few months ago.
It doesn't like something about your water.
I read that brains don't get along with certain softies or leathers.
My brain didn't make it.
I agree with Marrone. I have two open brains and they can be touchy, you should definitely try feeding more substantial food. I have read that many starve due to misinformation.
A piece of advice though, put some of that 'meatier' food on the other side of the tank a few minutes before you feed the brain. Otherwise your whole cleanup crew will jump all over the brain and steal the food. Basically you need to cause a diversion. Get them all away, then feed the brain.
