How strong are his halides? Montiporas like a lot of light, but not like
acros do. Could be some but not all of the zooanthellae have been thrown
off (perhaps just one type, but not another - hence the color change
instead of full blown bleaching...)

My first thing to try would be move the digitata lower..


err... just looked at the jpg... it ain't that high up to begin with (I
don't keep my sps any deeper than 2-4 inches below water line myself)

You still have other corals besides the montipora. And star polyps are
still in the Anthozoa class. Yea I can see the montipora in the picture.

I don't see anything in there that would cause a problem.
What's the reason again that you have that bottle in there?

How are your other corals doing? Or maybe I should ask, how are you
other Anthozoa doing?

Thanks Wayne,

My lighting equipment is the same as the store however the store's
lighting is probably about 4+ inchies higher off the water and his
corals are a couple of inches deeper in the tank.

This is my first coral. I have other items like a torch, star polpys,
etc at the bottom of the tank but no corals like the digitata.

All water tests seem fine except I do fight to keep my water hardness
up. I do the typical ammonia, nitrite, nitrate, pH, kh, calcium and
phosphate tests. Can you think of one I might check into to further
examine this problem, if it is one?

see the red/orange digitata in the upper right (under one of the
blue-green damsels) back when it was its original color.

Do you have other corals? If so what other corals do you have? Is the
lighting brighter in your tank than the store's tank? Going to a
brighter tank, can cause them to lighten their colors, and it can
also cause them to darken their colors. Also different nutrient
levels in the water can also make a change in lightness and darkness
of corals. And other factors of water conditions can cause a change.

I bought a orangish red digitata frag several months ago and it
looked great and grew fast for a long while. Over a month ago it
started turning pink and now it's very pink, I'm afraid to say
almost white pink. I've been reading about coral bleaching but
nothing really matches my situation. These have been pink for over a
month, maybe even a couple of months. The store I bought it from
has his "parent" frags growing great.

Any idea why this happens and what I can do? It's getting plenty of
light from my halides and actinics.

Thanks for the advice.
