i got one a few months ago.
well a mushroom grew on him and he showing a little skeleton.
hes also lost alot of color . i think i even have a baby anemone on him too.

it was starting to look bad and i moved it to a new bigger aquarium
its been in there about two weeks, its not receding anymore.
and its tissue doesnt look flat to its skeleton no more.
