If you would like a tank instead of a tub then definetly get one that opens in the front and is blacked out on the other sides like animal plastics or boaphile. I used to have both my bps in tanks and recently switched them over to tubs. I have noticed very little, if any, change in their temperment. In the wild they spend 90% of their time in rodent burrows or termite mounds. The only time they move is to thermo regulate or go find food and take over another rodent burrow. (except for mating season i would imagine )Typically I wouldnt imagine a bp wanting to eat a meal out in the open bc while theyre eating they would be extremely vulnerable to predators. This is why eating in a tub vs a glass aquarium makes them more willing to eat sometimes. At the very least, like i said before, I would really get a blacked out enclosure. After switching from aquariums i wont go back, at least not for bps. Im far from
an expert but these are just my personal experiences combined with the knowledge i have absorbed from some of the brilliant folks here.
