Overprotective snake mom/total noob question about enclosure size

[Regius_049]

If your snake is ~3 months older, I would guess he/she is somewhere in the ballpark of 100-150g. Your enclosure size is not really "too small" per se, but keep in mine enclosure size is something of a relative term. For example, some people keep adult BPs in 41 qt tubs and others keep them in larger plastic enclosures like a T8 from animal plastics. It is impossible to say which is truly better as I don't think reptile "happiness" can be accurately measured, assuming they have an emotion akin to happiness at all. Thus, I would say as long as your snake is eating well, growing appropriately, and shedding properly you are probably fine.

Generally speaking, many keep BPs around your snakes size in anything from ~5-6 qts up to 30 qts. Could you upgrade her to your 56 quart tub? Sure, it would probably be fine. Could you leave her in what she is currently in? Sure, that would probably be fine too. As long as the aforementioned husbandry criterion are met, you can pretty much do as you wish. I will note that some BPs are far more active than others, some may really get a lot of use out of the extra space, while others (more or less) stay in their hides all the time. It kind of sounds like you want to give her a larger enclosure, so don't be afraid to do so. If you start having issues like her not eating, add more cover/hides/terrain and the problem will likely go away. BP hatchlings clearly have tons of space in the wild, so any size cage with sufficient hides should work fine. The only caution against something too large is making it difficult for the BP to easily move from hot to cold areas, but you are unlikely to run into that problem with a 56 qt tub as your describe it.
