help w/ brain

i posted this in the LPS forums too but since this place gets more traffic mind as well...

my closed brain's skeleton is kinda showing. right now i dont have it attached or glued to the rock its just sitting there and yesterday i noticed a section touching the rock started to receed. today the skeleton was showing and the color was dissappearing around that area. wen i picked it up there was huge copepod taking up residence under the frag, could that be the problem?
anyways here are some pics...

test results...

calcium: 440ppm
alk: 8.2 dkh
pH: 8.4
salinity: 1.026
avg temp: 78.9

placed about 15" under 6 bulb T5's

Maybe too much flow? Have you moved it to a new spot in the tank recently? I've seen similar recession in a plate coral on the side that was exposed to strong flow.

Now that's something I never thought of!! I have a green brain that went to almost nothing. I blamed it on lighting (too much) so I moved the brain to my HOB fuge (made it into a hospital tank). Since then, the tissue that remained has taken off and it looks rather nice again.

I guess these brains like nice shallow, sheltered areas. How do they do in somewhat dirty lagoon regions?

i had it sitting in the same spot ever since i got it, and i havent added any new powerheads or increased the flow on any of my vortechs.

can amphipods eat brains? someone else told me that he had a problem w/ amphipods munching on their zoas, and i found this huge one right under it wen i went to inspect it yesterday.

Does it extend tentacles at night? How long have you had it?

i just fed it yesterday acctually, it took the food soon after i moved it off the rock it was on and placed it on eggcrate. ive had for 6 months.

just to be sure about my alk i raised it from 8.2 dkh to about 9 dkh to account for inaccuracy of test kits. i heard low alk can cause the leading tissue to receed.
