I found this on my glass this morning. He is apparently some kind of hitchiker. Looks to be some kind of starfish but it only has 3 legs. Just worried it might be bad.Sorry my camera really sux.

astreia (sp?) star of some sort- 99% chance it's harmless- I have a bunch and they don't bother my coral at all, just part of a free clean up crew. If they multiply too fast just take some out and toss them.

you can find alot of hitchhiker info on the main page, archives/faqs
