might get more answers in the saltwater forum, but I would be very hesitant to do so, especially with the size difference. I've mixed morays, but not those species, and it can be tricky sometimes
I wouldn't... Snowflake eels are more slender than the Dragon Moray... So he'd most likely end up being a quick snack for the Dragon Moray... I would try somthing like a Snowflake eel, Ghost eel, and Chainlink eel... maybe not all of them but they are around the same size
thanks I'm just going to have to start a new tank that's all my freshwater section seems to be getting smaller. should've just started out with SW than I wouldn't have to worry about them
