Nudibranch ID, anyone?

[stickboy_107]

Found this guy in my tank. Not sure where it came from or if it is good or bad. The colors are yellow and green in case you can't see them very well. If it is good, then what does he do? If not, I want to leave him out.







Any info is appreciated. Thanks!

No clue what it is but it almost looks like a baby sea hair.

I've seen those before...know they're bad...but can't for the life of me remember why.  Don't have time to look it up, but this might be a good resource for you...  Gotta run!

I found one of those to when dipping corals from CORA Swap. Was not sure if they were good or bad and could not find any info on them. It was cute   but I flushed it  
BTW: Great picture

Thanks guys. We kinda of thought the same thing. Figured if you don't know then it has to go.
