I had a snake in the past who would not eat anything other than live minnows
I was truly surprised when after setting it up a bit, she did go for a dead pinky floating in the dish with her minnows
right now I'm trying the same with another snake and so far, she's gotten the pinky out of the water a couple of times, but not eaten it
so right now, she's just going to get used to the taste a bit
but in a few weeks, she's going to miss a couple of meals
and then the minnows are going be skimpy
and that rodent washed to inoffensiveness . . .
we'll see . . .
if not - I'll try again another time
fish strips too
it's all I can do
sorry - I'm rambling
what I meant to say is that you try different things, go slow, be patient
feeding tongs work really well with some snakes
