ID PLEASE:new creature on glass.. possible jelly?

[alaskan84]

2 days ago, I pulled all my rocks out and scrubbed them down real good to help eliminate algae/detrius that was on the rock. This afternoon I noticed a very small creature on the glass. Its kind of star shaped, and has tentacles coming off of it. This is the best pic I could get of it, even with macro setting.

Ok, so i did a little searching, and it appears to be a hydroid jellyfish....interesting that I havent seen them in the 30 days my tank has been up, but after a good scrubbing, there he is. He appears to be quite clear/white. Can I assume that since he is not brown, that hes a keeper?

yep hydroid jellyfish. if you don't get a bunch of them they are pretty much harmless.
