tub set up

I am thinking of doing a tub for Calypsos home .
What quart size will he need ?
Can you place the uth on the tub or do you need a barrier ?
How should I set up the lid ?

How big is he? 15-27qt tub is generally a good size for juvies. If he's a tiny baby around 100g, go for a 6qt shoebox.

here are the sizes:

6qt, for baby

15 qt, for up to around 400 or 500 grams

32 qt, for up to 1500 grams or so

The size tub depends on the size of the snake. A 6qt is good till they reach around 350 to 400 grams. Then a 15 qt to around 1000 grams, then 32 qt or bigger.I like CB-70 for adults.
The UTH can be taped to the outside bottom of the tub. Be sure to regulate the temp with a reostat or a thermostat.
I like newspaper, use whatever substate you like.Don't forget to add a water dish and at least one hide.
The lid will have to be secured. For a single tub, small bungi cords can work or just some weight on it.
Hope this helps.
