I took in 2 bps that had it bad.

1. Quarantine. You don't know what else is wrong with it.

2. Newspaper in the tub. Change it very regularly.

3. Normal Polysporin twice a day until shed, then maybe once a day until the second shed.

4. Small waterdish. Keep low humidity.

5. Up temps a little to help with immune system.

Make sure that if you are going to handle the snake for treatment that you wash your hands and don't touch ANYTHING with dirty hands, (including the tap, use an elbow, or wash it after).
I would check the snake for mouth rot, and RI, but not right away. This snake is probably not going to like handling and prying its mouth open.

Good luck. It really is heart breaking to see the little guys suffering, but don't worry, the treatment is pretty fool proof from what I understand. Both the ones I picked up are 100% now!
