I saw one that was pretty large in a shop around here I didn't know of you picked it up or someone else.Barney came from a shop up in the Minneapolis area. He was sold as a Fang tooth but I knew it was mislabeled. I also knew he was something I had never seen before, nor had I seen anything that looked like him in pics online at the time. I still to this day have not seen another in captivity. Not saying they aren't out there, but they (Gymnothorax Prionodon) sure don't seem all too common.
I do know there is no way I could have the group of eels I have without having the ability to "grow out". Barney would have been eaten immediately as he was acquired much smaller then the rest of the group and was grown out in a separate tank attached to the same system as the rest. IF you're content with a single eel then great, but even a similar sized pair may take housing one in a grow out situation for a while. Especially if looking for a counterpart that Barney wouldn't eat.
We definitely all do things differently. I keep large eels and would not rely on a lil skimmer that would fit in a little sump. Ever seen what a skimmer does after a 2+lb feeding?
I haven't seen a skimmer like that but with some luck I can get closer to the level you are on.
