slug.

So this little green slug, hitched a ride on some life rock, he's rather cute, cleans off the rocks, and doesn't bother the fish. Im honsetly suprised he is still alive, the live rock was put in the tank to cycle it out. The tanks been running for 3 weeks.

It's a nudibranch. I couldn't tell you of its good or not. Never seen one quite like that.

I really wanna know what kind he is, I don't want to add my blue daisys when its time and have him eat them..the whole reason the halloween hermit was banished to the 65 in the first place. If worse comes to worse, ill throw him into the quarenteen tank.

I have similar ones that are more brown in coloration that pop up from time to time and don't seem to have harmed anything. That being said, I've seen my cleaner shrimp rip one to shreds, no idea why, and there are so many different types of nudis that's it's very hard to get a positive id on them. It does not look like the nuisance coral eating ones, and is probably just a filamentous algae eater if I had to make a guess. Do you know where your rock is from?

Fiji, Tonga, and Jakarta, if that means anything for the rocks.
I had to ask my friend who works at the LFS where I got the rocks, (3.99 a pound for some really great looking rocks because they ordered way to much.)

Nice pics!

looks like an algae eater to me! Couldnt be certain though without a lil research!

It's a polyclad flatworm. They generally prey on Snails, worms and small bivalves. There are a few herbivorous species that eat Diatoms. Since yours is a greenish color there is a fairly good chance that it just eats Diatoms.
