I have 12 inch fire eel, I bought it 2 weeks ago. I’m not sure how much to feed him. I feed him 4, sometimes 5 cubes of frozen bloodworms a day and yet he’s still begging for more! He ends up panting after his meal, which I don’t know if he’s eaten too much. I’m really confused and would appreciate some advice. Should I carry on feeding him till he stops wanting more?
