Probably not a baby, but not an older snake either. I will clutter the cage with a tone of stuff. I have heard 2 schools of thought on cage size.
1 being a big cage causes stress and makes a snake feel insecure.
The other being "Nature is huge and they make it in the wild." I think with all of the extra stuff I have here from the Royal would be enough to possibly over clutter the cage. I'll consider a divider if need be.
The plan is to get an established feeding snake that has been handled and is comfortable. I will check with Rio Bravo and the other breeders you mentioned.
I talked to Ed and he said if I was going to use a RHP, perches would be better than a shelf because the shelf would block some of the heat from the panel. I have a lot of questions as to how to effectively regulate a RHP with a thermostat. Probe positioning and such.
Our current Royal has a dangled probe that deals with the lamp, and the other probe is between the UTH and the outside bottom of the tank. That all seemed so easy.
The Proline is a totally different deal for me so I'll need help.
