They are very hardy eels.....and will eat mysis shrimp,brine shrimp,krill, tiger shrimp,octopus,squid...and pretty much anything meaty....I fed my eels some canned tuna and salmon.....They will grow pretty fast but only to a max size of 12 inches.....The Golden Dwarf Eel is not agressive and is a reef safe eel.....aloha Les
