I got my baby girl at about the same size. Her feeding response is very strong but I can't just throw a prekilled in there. I have to use tongs and after she strikes at the rodent, simulate a struggle which makes her wrap. You might want to try that.
I would also ditch the flood light and go with a under tank heat pad or panel.
