Bubbletip Anemone's health

I have recently put in a BTA in my tank (like a week ago) and he is not
looking so hot. Like a small part of his body (~1/8) is curled up
really small, the rest of him looks fine with his tentacles spread out.
That part that is shrunk I was afraid was the melting look that I have
heard about when they are about to die. I was about to remove him from
the tank, but he is firmly attached to a rock, so I thought maybe he is
all right. I have heard that when they die, they can really put a hurt
on your tank if you don't get to them right away. Anyway, the rest of
the anemone looks fine, with his tentacles spread out, just that one
part of him. Water params look fine. Lights are 4x65w Coralife PCs,
and 1 NOF. I thought maybe it was the lights and I was going to move
that rock to the top, but he is on a big rock that is a base piece of
my rock work. Anybody else seen this before?

Thanks!
