Acan Pest?

[athenagrace]

Hi everyone,
I bought this Acan about 2 weeks ago. It doesn’t look so great and it hasn’t been improving. It appears to be receding and just seems generally unhappy. Last night, before lights out, I noticed this weird thing on the edge of it and I watched it for a few minutes. I didn’t see it move at all, however, it was gone when I woke up this morning. I’m sorry it’s a bad pic, it was the best I could get. Any ideas?

If it is actually moving but it didn't move in front of you, it's probably not an amphipod as it sort of looks like in the pic... it could be some kind of asterina, snail, flatworm, or nudibranch, but I can't tell from the pic.

I think your task for the next night is to wait until after dark, look for it, and if you see it.... pull the frag, put it in a bucket, and try to get a better look or even pull it off to examine.
