Sad acan?

[Junktown]

Just picked this guy up at a local fish store. Think it is an acan, fish store guy wasn't sure. It was almost completly white at the store, but is starting to pinken up. Is this an acan?

A clearer pic would help but that looks like a favites to me.

If it is a acan, I would say it is an Acanthastrea echinata. If I'm wrong and it is in fact a Acanthastrea lordhowenis, the polpys are really retracted.

Either way, keep it low and in lower flow and feed it meaty foods every so often. You may want to feed it after the lights go out when its feeders are out. If they don't come out, kill the flow in the tank and squirt the food on the coral to illicit the feedeing response.
