First off congrats to you for taking these animals and knowing you were going to have to vet them! Not many people do that. Now a few things. Make sure your heat is on point to really reduce stress and bring these snakes back to health, also to help the CG with the RI fight it off. Keep an eye on everything else as they may be sick as well (he could have cross contaminated due to carelessness) I'd also give them a few days before trying to feed again. You want them to calm down and let them adjust before possibly stressing them with live food. Another thing I would like into is nebulizing (with F10 I believe) the CG with RI maybe it'll help cure him sooner. Other than that, I think you're doing a great job.

Btw Banana and CG are the same thing, don't let anyone tell you different. Use whatever name you like. Banana or CG, just stick to one LOL.
