Congrats on the new addition. It does sound a bit big for a male. I hope he turns out to be a she.

I would advise that you quarantine this new guy/girl from your other collection. I'm not sure about disease transmission between colubrids and pythons, but I would err on the side of caution. Minimally a couple weeks, just to make sure you have a mite free bp. I believe it's 3 weeks for eggs to hatch, if it happens to be carrying any.

Anyway, best of luck with this new (hopefully girl) bp. What a wonderful find! When do we get to see pics of him/her?
