Swollen Brain

[mjg]

I have been running my 12g for a couple of months now, and so far so good in terms of fish, inverts, and corals. I came home the other night however to find my green brain coral had swollen itself up to almost twice its normal size. Is this a sign of a problem?

 

I read that their expansion is a sign of health, but am worried that something may have irritated it. It looked as though it was going to burst!!!

 

Water quality seems OK, and the rest of the corals are doing fine; any ideas or comments?

Maybe one of your invertebrates took a lil' adventure over the surface of the brain. It happens I'd imagine. Also, do you see any new mouths? It may be splitting. My hammer gets all bubbly before its about to split so, who knows?

I have a red open brain..totally normal when they expand like that....its a happy brain.

Thanks for the info!
