Two BP's, two different worlds.

[renage31]

I have two BP's living in one 55 gallon tank, one is mine and the other is my friends. My BP is thriving, she took a small rat (50 grams) last Sunday, she is about 12 months. My other BP has been an utter disaster. I bought her as a young juvie, in shed, with no record of feeding. She was at the store for about 3 weeks, and I of course let her settle into her new home for about 2 weeks.

After two weeks I offered her a pinkie, with no interest. Luckily my BP cleaned up the thawed pinkie (with very little trouble). Waited another two weeks, tried again, with no luck. Then I moved on to assist feed. I did that for three weeks, and noticed then she was having hydration issues. So I completely stopped force feeding, and addressed the hydration issue.

Gastro-fed pedialyte for 2 weeks, alternating days (48 hour intervals). Then I went to a alimentary diet of chicken baby food, pedialyte, crushed tum, and a dash of veg. oil. I gastro-fed her once a week, for 4 weeks now. She has little signs of improvement. I've tried everything I can for this snake, what do I do?

Is this stress related? Is the tank too large for her? Is the fact she's with another BP 5-6 months older intimidating her? Do I set up my 20 gallon tank and separate them?

I know my tank is well suited to be inhabited by BP's. I have a repti-fogger, maintaining 60% humidity at all times. I have a large exo-terra waterfall for constant clean drinking water. I have a large water bowl for soaking/bathing. 200 watt ceramic heat emitter for hot side (maintaining 90-95 degree heat) and cool side never dips below 80. Two hides on the warm side, and one on the cool. Plus a climbing branch to get even closer to the emitter if they so choose (and I've seen my BP do).

I've always done as much research as I could before executing my next move, but I've come to a cross-road where I'm uncomfortable letting my friend venture out on his own caring for this sick BP.
