I have two Acan's in my system, presently. In the tank, they're right next to each other, one has been in there about 3 months, the other probably 2 months. Both have started to show new growth, in that time.

It may have started earlier, but I noticed today that my green Acan, the one that's been in 2 months, has started to show it's skeleton, in several places. All the polyps are still alive.

While I don't have any alk tests onhand, all my other LPS coral is doing well, including my other Acans which are still nice and fleshy, as well as my Blastos, Torch, Favia, Scoly and Acanthophylia all remain the same and healthy looking. My Scoly has even improved, since I got it in, is responsive far more on feedings it was when I got it, and remains pretty happy. So, no clue as to what could be happening here.

After reading online, most people seemed to suggest a 'dip' when this was going on, so I did a dip with Revive, and set it a little lower in the tank on the sandbed right next to my Blastos for now so I can better watch if it heals.

Is there anything else I can do to help it heal, before it fully is gone? Not sure how to feed these, but I know feeding can help a coral recover; I've yet to spot feed either of my acans.
