Unfortunately not. This was an ID for someone else from another forum. I'll contact him to see if he's found anything new, but he never sent new/better pics....
The part I left originally, was the eel was only $40 (Guy paid $80 for him and a 11" Snowflake as well ($40 ea.)). I think that eliminates a lot of options. I've heard of a ~$45 Blackspot Angelfish bought as a $6 chromis, but a $900 Kidado I just don't believe turns into a $40 Misc. eel. That being said, I don't think it's G. Eurostus, the pattern does look more snowflake/webbed/marbled/etc, then spots. With a lot of Muraenidae not even having pics on Fishbase, I personally would write it off as one of the oddballs that happened to come in.
