Its hard to say, I have racks with different sized tubs. I wouldn't put a hatchling in a super large aquarium personally. they require small hides that hug their bodies so they feel secure, smaller water dishes. when you have a tiny hide and you are heating 25% of the cage with an under tank heater that really wouldn't work with a tiny hide for a hatchling bp. Like I said earlier what I use is small clear bins from Wal-Mart the ones for my hatchlings cost about 5 bucks, next stage up about 7 bucks and the ones for my adults about 12 bucks.

Also adult females get a lot bigger than adult males usually.
