Thank you for your advice. I advice you to increase the height for your snake. 15 inches height is insufficient. You should give your snake a chance to climb specially if it was a male. After Regius_49 did the calculation, he found out that your enclosure 48" x 24" x 15" is 17,280 cubic inches and my enclosure (2' x 2.62' 3.30') is ~29,880 cubic inches (43% difference) for me . So i have much more space than yours, even though floor space is more important. I would prefer my enclosure over yours because my BP won,t be happy in a glass tank. Even my floor space is bigger than a 40 breeder tank. mine is 744 sq and a 40 breeder tank is 648 sq. Additionally for comparison, an IRIS CB-70 (37 qt tub) is 33.5" x 17.8" or 596 sq. inches of floor space. I have quoted these numbers from Regius_49.
