ID tank of the month inhabitant.

I was wondering what the blue and yellow eel (or is it a fish) is. It's under the GOAL subtitle on this months tank of the month page. I know it's kind of a stupid question, but I really want to know.

I'm pretty sure that's an adult Engineer Goby. They turn that coloration as they age. I saw a few of those at the LFS, and they do look like eels.

It is indeed an engineer goby, aka convice blenny. Interestingly, it is neither a gobie nor a blenny. See the link.

I see that the fish can grow up to 18 inches, any idea how long it takes to get there? I also wonder if he would eat my other fish when he got larger. I have 2 percula clowns, 1 royal gamma, coral beauty. I'm looking for another interesting fish and this one has sparked my interest. My tank is 75 gals.
