I've owned a female since Thanksgiving. She was captive bred and is now probably a year old. I've never dealt with such a finicky individual. I tried frozen, no go. Bought live rat fuzzies and originally had success. She then stopped eating them and went to striking the poor things in a defensive manner and not eating. She is now thriving eating frozen mice hoppers bi weekly.
Some advice not related to possible health issues.....
1) Most care sheets are too high with temps. I'm now at 79-82 and she's finally thriving. 2) They live in leaf litter along rivers under foliage so no hot spot. 3) They love to lay in their water dishes. This is not a sign of a problem as with other snakes (although there still could be one) but there's definitely a problem if they aren't in it ever. Make sure yours has an adequate pool. Mine will go in immediately after feeding and stay there for days. 4) They are campers. They don't move. So they expend little energy. Feed bi-weekly at the soonest. 5) They are shy. Make sure hiding is available.
Hope this helps. I'll share pics.
