Any ideas what this is?

I recently purchased a rainbow bubble tip anemone that was on a rock and after getting it home and in the tank I found this little guy hanging on the side of the rock. Anyone know what it is? The first picture is under normal light and second is under black light.

Oh and at night it seems to stretch its many clear tentacles out.

Very hard to see based on distance and blue lighting. While it appears to be a hydroid or ball anemone, it may be not and Brighter white only intensity will be best

Yeah, a ball anemone/corallimorph would be my first thought (they're not actually anemones; they're actually related to soft mushroom corals). They don't really seem to cause problems, though they sometimes reproduce quickly.

Thanks for all the replies guys. I got it in a spot where I can keep an eye on it to see what it becomes.
