Got this with some rock I got off a fellow reefer, I think it is a slug of some type.[IMG]http://i1139.photobucket.com/albums/...r/P1060906.jpg[/IMG]

It appears to be a nudibranch not sure what type but use caution with them most species are not what you would call reef safe

Flatworm, get rid of it and keep an eye out for more http://www.wetwebmedia.com/fltwmid.htm

This thing is 3X the size of a quarter, can flatworms get that big?

This is a very large, very predatory flatworm known to feed on snails and sometimes mollusks. I had several of these come in on a coral, and it took about every chemical in my arsenal to kill them. Once they make it in to the aquarium, they’re nearly impossible to remove.

Wow, totally wouldn't have thought that was a flatworm either. That sucker is huge, lol

It's gone to flatworm heaven.
