Should I be worried about my acan?

In december, something hit my tank and from the help of others on here, we sort of pin pointed it down to a bacteria bloom. Long story short, all of my LPS withered down to their skeletons minus my trachy. No other corals were affected at all.

I just received two acan lord frags on wednesday. I've been noticing this stringy stuff coming off the edge of the flesh from them. I believe it is clearish, but it is hard to say since microbubbles have been sticking to it(not brown though).

I'm worried because this is how my LPS corals that died started out. They had stringy stuff coming off their flesh and then eventually their flesh was gone. It is hard to see in the pictures, but the flesh on this acan lord went down further on the skeleton. It has receded up to the polyp. The polyp itself looks great, but the skin receding is worrying me.

All of my parameters are in normal reef range and have been stable with what my tank is usually at. I have also recently added a seriatopora and it has been looking great, which I assume means my water quality is up to par.

Should I be worried at all? I'm sort of freaking out because it seems like Deja vu with what happened to my LPS corals and these are the first pieces of LPS I have added since.

 

To be honest it looks fine to me. It's inflated nicely and the feeder tentacles are just poking their tips out (which is exactly how my Acan looks). Could be just stressed out from the shipping and being placed into a different tank. Mine was all snotty for a couple of days when I first got it, and it didn't inflate fully for, if I remember correctly, three days.

I'd keep an eye on it, but I wouldn't be overly concerned.

 

I'll definitely keep an eye on it, thank you.

I saw tissue receding, stringy stuff, and LPS and it just brought back bad memories.:-/
