This is what a dead acan looks like

Ok this is a dead or dying acan. There needs to be a basic photo of one to ref. 12 dollar experiment on acan hardiness. This is what happens when temps take a fluctuation due to power outages or a heater gets a bit too warm too quick after when salinity is too close to 1.023, light shock and why you do not touch corals even with gloves. Sorry but the lfs I got it from had atip infestation, strange parasites on the snail shell, hermit crabs eating coral and the water actually stunk. No way quarantine was going to cover all that. So experiments happen we all can learn from. See how the skeletal formation is deformed? Tap water does that. So in conclusion, to/do water is important, acans are not very hardy, cannot tolerate temp fluctuations, salinity fluctuations or handling. Now you know. Hey for 12 bucks I will have a cool skeleton coralline can cover. If it actually resprouts, that would amaze me. Looks to be barfing zooxanthellae. Slime disease?

Dang auto correct.. Hopefully you get the point.

That honestly surprise you but if there is any tissue left even a super small piece,tuck it off in a corner and drop a small piece of food on it and I bet it will grow back.

I had a couple of acans a while back that looked like yours. I ended up taking them out of the tank putting them in a dish with tank water and dumping mysis over them. After they ate a few pieces of it, I put them back in. They both came back in short time. Good luck!
