I got a green wolf eel (Charlie) the other day. He's active and already eating from my hand 8). Im having trouble finding any good information on caring for them though, I was wondering how much I should feed him (hes ALWAYS on the prowl...). Also from time to time he puffs his head up and sticks his gills out and twitches (almost looks like he's trying to puke...) does anyone know what would cause this?? Thanks!
