They are hard to make the switch,over to frozen
foods.But it can be done,i just put a silverside
in the current,looks alive enough to fool him
and he goes after it.Or you can use feeding
tongs to hold it and move it across the water,so
that he things it's alive.Some times they can
fool you into thinking that they are starving,
mine once went 15 day's with out food.They are
nocturnal so feeding at night works best.
