Unknown coral. Purple with pink polyps.

[JSeymour]

I actually found this coral "hidden" in a lfs's tank. Looks like it had fallen down and been forgotten. I got a live rock price instead of coral price due to the damage. It looks like a promising coral though. It had much heavier algae infestation, but a pygmy conch clean it up a bit. Sorry about the poor quality, my camera doesn't have a macro feature. It looks to me to be a Astreopora, Turbinaria, or Cyphastrea sp. Cyphastrea has much steaper corallites though. It's corallites are very round.It is at this time purple with pink polyps. The polyps did slightly expose themselves at night. Any ideas on what it could be? The store owner had no idea what it was. I'll try and get a better picture, no promises though.

The rock it's on is 5 x 4 x 2.5" for scale.
Being damaged by improper care, any tips on recovery?

Wrong forum, but my new clam from the same place.

Looks like my cyphastrea decadea from that pic. Let me find a pic for you. Increase the flow. If it is the cyphastrea, middle to low on the lighting.

from that pic it looks like closed up zoos.

Better close up pic please

Possibly a Cyphastrea Decadia. A better pic would help though :)

Well, my Gammaridean Amphipods have absolutely devoured all but a couple dozen polyps. It was 100% them, I watched them gather on it and eat it. After doing some reading, this seems to happen to some zoanthids. I also haven't been able to get a better picture. I moved it to a much higher flow area, the gammarus don't seem to like it there. If it can recover here, hopefully it will polyp out and an id will be easier. Maybe I should repost in the zoathid forum, but do zoanthids produce a thick encrusting calcium skeleton?

They were probably eating otherwise doomed polyps. It's not a zoanthid colony if it has laid down a skeleton. Without a better photo anyone's guess is a shot in the dark.
