For 80 bucks, I'd get it IF it is, in fact a true golden moray. Find out the sci. name. If it's gymnothorax melatremus, buy the thing immediately and laugh all the way home at your fantastic deal! That's the so called "dwarf golden", and many stores don't know what they're selling (as I've learned on this board!).
If it's a Goldentail moray, sometimes called a Golden Moray, and its sci. name is gymnothorax miliaris, you'd be getting a good deal, but a very different eel. Goldentails are very attractive, in my opinion, but are 2 foot eels full grown. It's probably worth the 80 bucks, though. They're not gold, BTW--unless you find the light colored variant. One I saw at my LFS was a nice, dark mottled one, and sold for $105.
Also, if you have small fish, the eel will likely make lunch out of them.
