Which is the easiest species to keep of the genus Enchelycore not counting the dragon eel

I'm searching one eel from the genus Enchelycore that isn't the dragon eel, anyone knows what eel is the hardiest eel from that genus?
Also, I have heard about one eel from that same gender that just measures 34 cm (~13")! It's the Caribbean Chestnut Eel, anyone got experiences with that eel? is it easy to take care of?

Ok, so now I founded a shop that haves the Caribbean Chesnut Eel and I heared that have the same care as the dwarf moray eel, so it will have a 216L (~57G) tank with only that eel or some fishes.
