As far as how you feed it...I hand feed my SFE atm but i make sure that my green wolf has had more than his share because i like my fingers attached. My SFE wouldn't touch the brine or krill i was offering him (wouldn't even come out of his cave most of the time) but when i would wave a silverside close for the Green Wolf he would get real friendly, leave the cave and suck the silverside back inside with him. He still doesn't finish a whole one so i cut them up in half and he eats them pretty well. So based on what i've read i would try any number feeding techniques and see what your guy likes. I also bought mine as a baby which contributed to the hand feeding, along with his flat teeth.
