Help! ID this fish..

[jpines]

I bought some a few margarita snails and blue leg hermits, and also picked up a few larger shells from the lfs. I put everything in about 6 hours ago. Came back to check on the tank and half the snails had fallen off the glass and were upside down...so I flipped them. As I was flipping one of the shells over, this black and white fish swims out!! I only got a quick glimpse as it swam under the rocks and I was able to get a picture (not good, but maybe it'll help). The fish uses it's front find to perch up in the sand (goby-ish). It has a really large dorsal fin (reminded me of a butterfly)..not sure what this is. Afraid it may not be reef safe or good for my other fish. Any ideas???

Some type of shell swelling fish. Probably a blenny. Their was probably a blenny hiding in a shell and they happen to give you that shell. It was probably scared so it just decided to come out when you moved the shell. As far as an id I really can't say anything.

Looks like a lawnmower blenny. You just got a freebie.....

 

[jpines]

Yep. That's exactly what it is! Thanks man. Stress level is going down..

I was pretty freaked out when it happened. Didn't have any idea the fish would hide up in the shell like that. Pretty cool though..he's already nipping on some rock

If it has a really large dorsal fin it may be a sailfin Blenny

[jpines]

Yeah. After looking at pictures I'm pretty sure it's a sailfin blenny. He's got a really large dorsal fin when he decided to stick it up

Definite blenny of some sort

 

[jc_k]

Are you keeping it? I caught a blenny about 2 years ago ( out of the ocean ) and it's never bothered anything and loves algae and is all VERY fat. One thing I noticed is he isn't getting any bigger and he's only about 2 inches.... Just thought I would share..

 

[Reefplumber13]

How did you catch it? Lol
