it's really hard, if not impossible to frag an open brain. they only have a
single mass of tissue, and tearing it will usually deflate and kill it.

anyway, the OP has a closed brain, which does have individual clumps of
tissue, and yes, that can be fragged, if carefully done. it won't be round
anymore of course. i've seen this problem diving a lot now. i've heard that
dips may help solve the problem, but i don't remember with what. iodine,
antibacterial?

Xerces,

It sounds like your open brain is suffering from RTN (rapid tissue
necrosis).
The best option is to frag it, trying to salvage any living tissue so it
can
live. Check in the SPS forum on Reef Central for more advice.

I have a 46gal tank, 20gal sump. 60 + lbs of LR. Lots of other corals,
all doing well. Just recently, my closed brain started to show a dead
spot the size of a quarter... now the dead spot is over 50%! Water
tests fine, SG 1.025 CA 420~ no Nitrates or Amnonia... I have a open
brain, bubble coral, cup coral, xenia, antilia all doing fine...The
onlything that is different is my bubble tip is getting ready to
split, and hanging near the surface... suggestions?
