I feed my lion every time I feed the sharks (Mon, Wed, Fri). I think youll have to find someone you trust to come in and feed the eel at least twice when you are gone. Dont forget to have some water pre-mixed and ready to go to replace for evaporation that will occur when away. SHOW this person how to do it. When I went away earlier this year, the person I chose to look over my tanks didnt top off the 125, so the sump went dry and burned up my two 700 gal/hr pumps.
