Enclosure size options for juvenile BP

[dakski]

Back with a new question! (I would have just added to my first thread and edited the title to indicate a new question was being posted, but I don't see an edit option - correct me if I'm missing it?)

I'm going to be building my own enclosure and would like some opinions on which dimensions would be better for a juvenile BP. The snakes I've been looking at on Morph Market tend to fall in the 100-250g range depending on when they hatched in 2020. The two enclosure sizes I've plotted out are 30"x18" or 28"x16" (height probably 12-14"). I'm happy to go bigger (or smaller?), I'm just running into conflicting info on whether bigger is in fact too big for younger snakes. As far as hide box size, am I right to think the medium RB box is too large for the size of snake I'm looking at? In the picture I've cut out a medium box size paper, and a smaller one with dimensions of a small hide I found on Amazon since the Reptile Basics small seems too small. Which would be better to start with?

BP's like to feel secure. So, generally speaking, smaller is better for younger/smaller BP's.

Honestly, I've broken that rule with snakes, even BP's before, but you have to have an established eater and clutter up the larger tank like crazy.

In other words, they need to think the bigger tank is indeed much smaller than it is and do not have to go far to find shelter and a safe place.

Highest degree of success will be a smaller, cluttered, tank. Lowest degree of success, will be a larger cluttered tank.

I've had success when I quarantine in a small tank, get a snake established, eating, make sure they are healthy, etc. and then move to a larger tank. My quarantine period is a minimum of 90 days. I often use small PVC tanks for this purpose - like 10-14G size. I've had success with small glass tanks as well, but it's harder to keep the humidity in and the temps correct. However, if costs are a factor, that is a way you can go.
