Fuzzy nut goby?

[mtfatwork]

I saw this on a wholesale list, but I cant find a pic of one, or any info on them. Anybody here know a different common name for it, or the real name so I can look it up? I found reference to a gumdrop goby (green clown), being similar, but the price difference is pretty severe, so I am pretty positive they are not one in the same.

any help would be appreciated,
Thanks,
Mary
