My clown fish came out of her usual "home" in a piece of live rock and she seems to have bug attached near the base of her tail.She kind of laid in the sand for a min then might have been rubbing on a rock. I caught a quick glimps of a clear bug(it looked like the front part of a potato bug but had a fan tail like a shrimp) it had 2 black eye spots, and it looked like it might have had some small legs in the tail end.She was swimming fine but went back in her spot before I could get a picture will try if she comes out again.She doesn't leave her little cave offten and I usually only see her head so I don't know if it has been there long or if it is even hurting her .She is about 1 1/2 -2 inchs and the "bug" is about the size of a potato bug.Any ideas on what it might be and how to remove it,or if i should.Couldn't see how it was attached but it was on there pretty good with all her swimming and moving and not falling off.
