What is this? Good or bad?

Sorry for the bad shot. He keeps moving around so it's hard to get a good shot at him. He's very pretty but I'm wondering if he's good for a reef tank. I'm not sure how long he's been in my tank. I just found him today in my frag tank while I was fragging some corals. He's about 6"-9" long and very pretty when fully stretch out. I don't have any problem in my tank at the moment and I like to keep it that way. So is this guy reef safe? What's the common name for this nudi? Thanks for the help.

It's a nudibranch. Don't know if it's bad or good as there are like a million different kinds of them. Some good and some bad.

Looks like a lettuce nudibranch to me. They are reeef safe, and a lot of online stores sell them. See this link... http://frugalreef.com/wiki/Lettuce_Nudibranch

if youve got a lot of flow...i.e. big pumps...i would take them out...they always seem to find there way over to them.

looks like a lettuce nudi to me. i have a couple of them and they are fine in my tank. i do ocassionally find them in my filter bag though. :) although they always live thru it and end up back in the tank.
