Need a nudibranch ID

Just found the little bugger cruising around in my coral tank here at the store; fully extended he's maybe a 1/2" in length, 1/8" in diameter. Black eyes, line of black dots down the middle of its back. I was thinking it might be a baby Black Margined (Glossodoris angasi), but he's fairly small at this point.

I don't see a gill on his back...looks like an arminid nudibranch to me. They feed on soft corals. Folks on here often find them as hitchhikers on "clove polyps."

Cheers,



Don

Thanks Don. Should I be worried about having found this little guy? I haven't seen any other since.

Yeah, it's likely fairly specific in its food requirements, but the bad news is that its food species is probably one that's in your tank (or it wouldn't have hitchhiked in). I'd remove it, and keep a lookout for others. If you end up with a bunch of them, you'll probably notice one, or some, of your softies not doing too well.

Cheers,



Don
