You don't NEED a hide at all in a tub, you can use one but it's not a NEED.
I only give hides to shy snakes, out of 20 snakes in house only 3 have hides.
I agree with the others, buying for one snake is much better than breeding, the overflow of unfed will get you, lol.
Also with tubs there is no need to spray, humidity is generally not an issue.
