My BP "Monty" has been growing like a weed, almost 5 inches (sorry, no scale) in the last 4 months. He is in a 10 gallon, and I am having a bit of a cram putting a big water bowl in(had humidity issues) and 2 appropriate hides. He is now 25 inches long. Should I make the change to his adult enclosure(a 40 breeder glass tank) 36x18? Or should I opt for a 20 long(don't currently have one.)?
