Acan. Problem

[Senn]

Have a problem with the Acan I just got. First off I did a dip on it before placing in the tank. Stayed closed for a few hrs.before it opened up and started to feed.
Last nite I looked at it whilst doing the ritual coral feedings and it looks like the tissue is starting to/is receding on just one of the polyps. It looks like it's right near the mouth. I moved it last night to put it in a lower flow/lighting area and I am going to continue the feedings like normal. All of the tank params. are within the specified limits.
I'll try and get a better picture if I can. Any opinions will be greatly appreciated

Thanks

It is actually about 6 inches behind the frogspawn

sweepers can extend up to 10 inches.

Look at the hole and watch for any movement comming from it. A lot of Acan Echinatas come in with tiny parasitic crabs, if you find one pull it out with a tweezers.

you forgot to mention you did a freshwater dip not just a dip .
