What is the right size and best way to set up a tub?

[Spaniard]

Not trying to take this post over just had a quick question. Im getting 2 new BPs and have 12qt tub racks goin in how would i need to set these up. Will one hide be sufficient for them? Thanks Steven

Most snakes in a rack systems will be fine with only one hide. When the tub is in a rack it is essentially on big dark hide for the snake.
