Update:

Actually, the replies to this post have been EXTREMELY helpful. I can say that today 8 of 10 ate and out of the two that didn't one still has an RI and the other is still adjusting and very skittish.

I tricked Isabelle into eating in her tub. She "kills" it right outside of her hide and drags it in!

I fed Titus and Corena live hoppers, a little bit more mature than the last try with live and kept a very close eye on them. Both of them took the live! And Corena, MY WORST FEEDER, I even tricked into eating a F/T after the live. WOOOOOOHOOOOO!!!! Maybe the curse is over for a little while!
