need help!

[makana]

I'll try and get a pic tomorrow. I just finished the water change and the coral is all closed up. The tissue on the bad side appears to be receding and the skeleton is exposed. I checked the new water and calcium was only 400 and alk was 8.96dkh.

There is a hermit crab, cleaner shrimp, clown fish, and chromie. I havn't seen any of them bother it and none of them are new, but I guess it could happen.

is there any other corals touching it?

could it have gotten stung?

I wondered the same thing but from what I read the open brain doesn't have long enough tentacles to reach.

[Flash]

brains have a sweeper tenticle that can sting. If the side that is damaged is closest to the brain, I would try moving them atleast 4-6" apart for a while and see if it can bounce back.

I had a ric sting a head of candycane and it went right down the the skeleton and to me was completly gone... then 4 days later i noticed it bouncing back SLOWLY... but it has now come back!

I'll move the brain farther away just in case. I don't think they are close enough together to be a problem though.

[makana]

should I be dosing to bring up the calcium and alk?

One thing with bubble corals is if they are in a high flow area they will not open. Is it in a high flow area?? If so move it a bit so its not in direct flow.
