I purchased it from coralsoftheworld1. They arent the same one that was mentioned in the past on RC. they had good reviews though on ebay. They have 1 more still for sale as of yesterday. I'll update when I receive him next Thursday.
They are the closest thing to a reef safe eel. They typically don't bother your shrimp or fish. They stay small, only getting about 10-12 inches long. So if you want an eel in your reef then the GDM is the best option IMO.
