I just joined this site because I have some fire eels n I was wondering what's the best food for them to put on weight? I feed mine bloodworm n other frozen food, earthworms and high protein pellets! But my 2 biggest 1s ( 10 inch or so) don't seem to be bulking up? I feed them pellets every day, frozen every other day and earthworms prob twice a week that I get from my own garden! I don't use pesticides in my garden because of my kids n dog n I wash them b4 I put them in. Cheers.
