Most if not all eels should be fed 2-3 times a week to cessation. Generally in the wild, morays will go oit on an evening hunt and gorge themselves and then retire to their lair for a couple days to digest. Feeding an eel everyday will only burn out their digestive system. Many eels will go for months without eating with no problem what so ever. I will starve my eels for a week purposely to clean out their system. You are not dealing with a anthias. Eels are sedintary and should be treated as such. If you have ever kept a snake, then follow those ideas. Tim
