Looks about right…he should be fine with that.
FYI, if the snake is being "active", the husbandry setup may not be the best…most BPs are pet rocks, and prefer to hole up in their little hide boxes rather than roam around. Also, having the tank TOO big can add extra stress to the snake, as they will think that they are too exposed.
Are you planning on getting more BPs in the future?? They are addictive, and you may soon find that you don't have much room for 4-6 glass tanks in your reptile roomI'd consider tubs at least when you get your 2nd or 3rd BP…I know the glass tank I have is really hindering my purchasing of more snakes.
