I have kept all of my bps as small as 200 grams in 41 qt's in an enclosed rack without hides, as long as temp and humidity is right they do fine for me. I also have custom cages I built that are 16" x 48" and I give them each 2 hides in these and I have never had a problem in them either. I have had snakes go off feed for awhile but they were pounding food in the same cage before and after going off feed so I think its for reasons other than cage size.

I have noticed allot of bps will go off feed between 700 - 1200 grams without any change in the enclosure. I'm not sure why but the majority of mine did this then went right back to pounding food without making any change's in the enclosure. What I have noticed gets the females eating again is introducing a male for a week they don't breed but they sure go back to pounding the food. You do run the risk of the female getting gravid but it has not happened to me yet. I have tried this several times and it worked every time.
