I have a rack from animal plastics. I have them in Sterilite Box 1753(15qt) and Sterlite Box 1755(32qt). The large is pretty roomy for males but the small does well.
The males really do stay a lot smaller them the females. A lot smaller. I'm not really fond of tanks because they just seem to be too much work and they take up a lot of space. I don't have an adult male yet but I have a friend with a couple and he keeps them in 15 gal tanks and they have plenty of room. A ten would probably work but I like to keep things roomier.
I like tubs in general because they are easy to maintain, cost effective, and really comfortalble for the snakes. I know a lot of people perfer tanks and other enclosures that show their snake off to the best advantage but its really hard to show off a sand boa![]()
