you can keep American eel but LFS need a license to sell them!i cant keep American eels near me for some reason there not allowed is what my LFS said
Depending on what else will be in the tank, a large tire track eel or large fire eel is impressive. The tire track eel will eat small fishes and frozen. The fire eel will usually take worms and maybe frozen prawn if you are lucky.
