Do you still have your dragon?
I have a 18' HDME in a 6ft 125 with a few cleaner shrimp and damsels. Ive had him/her for about 6 months. I'm always interested to hear what the experiences others have had with these eels and what their set ups are. I know a 180 would be best but its just not feasible right now. At the same time I've heard of them living for years in a 125 with out any issue.
