Snakes don't like to be in a drawer or rubbermaid just as much as they don't like to be in a glass tank.
Rubbermaids used in drawer like racks are what breeders use - people who own and produce hundreds of snakes.. The racks I have seen come in a minimum of 5 or 6 drawers/tubs - which can house 5-6 snakes.. (doesn't mean someone with less than 100 snakes can't have a rack..)
Your boa would probably be happier, because of the space, in your decorated aquarium than in any tub or drawer which has limited space, but if you decorate it the way you wrote, you probably won't see him much and will have a very hard time taking him out, because he will be comfy and cozy in his hide spots, considering the ambient heat/humidity is adequate.
If you want the simple/best solution, in my opinion, go to www.boaphile.com and look at the cages/racks.
These are built and sold by Jeff Ronne - who has been breeding BOAS for about 15-20 years or so...
Made by a boa breeder (also cabinet maker) for his boas - not by anyone for any snake - again, by a boa breeder, for his own boas.
I swear by these cages and wouldn't waste my time or money on anything else.
Sure there are plenty of other similar cage makers, and other old favorites...
I still have nothing but Boaphiles...
got rid of all my Neodesha's, wooden cages (thank the almighty!) and even new Visions.
You'll find TONS of important info in the Boaphile ThinkTank too. Check it out!
