hello,
is it a reproduction or is it ill?

that looks like old damage to me, look how the skeleton has coralline and all sorts of other stuff growing inside the rim

Do you have this coral in the sand?

The coral is not in good shape. These are tough corals so it can turn around, but it's environment will need to change. It's suffering from an infestation of Ostreobium. A calcium carbonate burrowing algae. It's common when nutrients are excessive. The tissue of the coral should overlap the skeleton all the way around. All of the tissue in that pic as receded. It's unclear if the tissue of Elegance in this situation recede because of elevated phosphate, or if the elevated phosphate fuels the algae, which causes the tissue recession. Either way, the coral needs to be moved to a more nutrient poor environment. If left in this environment, the recession will most likely continue until the coral dies, or bails out. Which will also lead to its death.

thanks for your help

i don t think it's a problem of too much nutriements cause my rocks are clean, my sps are colorfull.
The " allien " in the catalaphyllia is not as pink as in the first pic, in fact it's the same color than the flesh. It s neither coraline nor algae. it seems to be a litte baby of elegance coral . it s bizarre :twitch:

Beautiful tank.:eek1:

How long have you had this coral?

I have to agree with you. This coral should be able to improve in this environment. You may want to think about reducing the flow on it though. The algae in its skeleton should die off and the coral should be able to resume depositing calcium carbonate.

There is a Gall crab that is common in these corals. They cause depressions in the coral in the same area your coral has the depression. Yours doesn't look quite like a gall crab, but photos can be deceiving. If there is a hard spot about 1/4" or less in diameter, down in that depression, it's most likely a gall crab. If not, it's probably just an area where the recession is worse than others.

I think when he said that the clam 'is sick' he was using slang to say that is a really nice looking clam!

[elegance coral]

That round thing on the right side, between the flesh and the skeleton is a gall crab. IIWM, I'd remove it.
