I actually use vision tubs (that's what's in my rack). However, smaller males can stay in 28 qt tubs with no problems. If they (or you for that matter) feel like they are too cramped, you can put them into 41 qt tubs. I just don't take up that tub space when I can use it for breeding females.
For your sake, you can do hatchlings - 200g in 6qt, 200g-600g in 16qt, 600-1000 + males in 28qt tubs, and breeding females in 41 qt tubs. That should be fine. Just watch your snake's behavior and if they go off feed, trying a smaller or larger tub, hides or no hides.
