When to change tubs...

When do u guys go to a bigger tub..i have a 300 gram male in a 15qt tub seems tight in there with 2 hides..im afraid if i take out the one hide on the cool side he wont go to the cool side and always stay on the hot side..my next size tub up is a 28qt tub is that to big for him yet at 300 grams..

I usually upgrade from 12 to 28 at around 900 grams. If you upgrade now you risk the snake going off feed. I usually keep hatchlings in 6 qt until about 300 grams

I use 1 hide in my 15qt tubs, they are kept in a rack.

It is not too big if it doesn't stress out the snake. You could attempt it, and put him back in the smaller one if need be.

I personally do not use 15 quart tubs. Mine go from 6 quarts to either 28 or 32 quart tubs.
