That's the fun of common names. Sleeper, fat Sleeper, Jade Goby, Gudgeon, etc.
Your fish only has one scientific name. I know it's a Dormitator, which species? I'm not that sure since I'm no expert at identifying between the species but it is most likely Dormitator maculatus. It gets much larger than D. latifrons, another Dormitator species that may also be encountered in the hobby.

I think down under we call these gudgeon and americans/the rest call them goby's.

Technically they are more correctly stated as gudgeons as their pelvic fin does not fuse into a suction cup as they do in gobies.

My guess is some type of goby.
