Flat slug looking thing

[Willba200]

Hi, can anyone i.d this for me? Good or bad?

It's a flatworm. I've seen that one a few times here and there and not seen any damage from it.

Ok thanks, it just started crawling out of my live rock. Had the tank for 5 months

Just keep an eye on the corals. If you see a big hunk missing, I would expect the flatworm to be the guilty party. I don't think so though.

Ok thanks, it's a weird shape. Earlier it looked like a star fish, then all of a sudden it cartwheeled across the tank and the flow is not that high in my tank. Guessing that Is how they move?

Will it eat algae?

I have no idea why it's all curled up like that. They usually scoot across the sand and rock like any other flat worm. I don't know what it eats. that's what we must find out

It's massive. I can't belive I've not seen it before. Gonna post a picture of my zoas on the other page as I don't think they look well. Wondering what your thoughts would be on this one? Post it in a couple minutes.
