Pseudocorynactis

I believe that I have a few Pseudocorynactis (pests?) in my tank. I first noticed it in my fuge. Recently I have spotted two I'm my dt. They only come out at night. No bigger than a quarter each. I have a total of three that I can find. Should I work on getting rid of them? Tonight I will try to get a picture to post. For now I found a pic online that is similar or the same as what I have.

 

Have a few in my tank and never noticed them harm anything or spread like an infestation. They seem to dwell in dark areas and don't bother my corals. So I just leave them. Unless someone on here tells me otherwise they are staying

 

I guess that I am not concerned about them harming corals as oppose to the infestation, thats my issue.

 

I have one too, just keep your coral away from them and the coral will be fine.
Although i believe Mr.Bill (fellow member) lost a regal blue tang to one of these little guys.

 

These do not grow large enough to harm a tang of any real size.

There is a Pacific one that gets decently large...

 

corallimorpharia harmless critters. I wouldn't worry about them too much.
