My 29 Gallon is in the middle of it's cycle and my wife has noticed an interesting creature on the Live Rock I purchased. It looks like a little green circle, like a piece of green thread in a circle. It seems to have little clear tenticles with tiny white things at the ends. It hides inside a small hole in the rock and comes out quite often. When it is in the hole you really can't see it at all. I will include a few pictures, he is like halfway out at this point.
I'm kind hoping it is a good guy, cause I don't think my wife would let me harm it!
I have searched around the net for this thing and have come up with nothing. I would greatly appreciate any help that could be offered!
