I was at Blue World yesterday and they had their "little blue world" nano section set up, which was really cool to see. I ended up buying this blenny while I was there, but I have no idea what type of blenny he is. I tried to google search some blenny images but I had no luck, anyone know what type of blenny it is?

He's a really cool looking blenny and he sort of walks around on the sand with these two skinny little leg type of things.
