I just got the last odds and ends for my first tub set up and I placed the hides and bowl in the tub to have a look how everything fits. It seems prettttttty tight, this is a 6" water bowl and the hides are the small hides from Reptile Basics. I am looking at snakes between 150-250 grams and was recommended to start with a 15 qt tub. Is this going to bed too small and cramped for a snake of that size?
