Oh yea, i know I will get different opinions. That's what it is all about =)
First time cleaning the tubs after swapping them, I was like " Wow, this is soo much easier!". Also with 7 snakes now, the amount of space that the tubs take up, compared to how much space 7 ~20gal+ enclosures would take up is a huge difference, especially in an apartment.
I have just noticed decreased activity at night and it got me to wondering if they actually 'enjoy' it less than being able to roam around and explore at night. I always kept larger than recommended enclosures. I would just keep an extra hide or two plus lots of 'extra' things to fill the gaps. Never had issues with feeding or aggression, still don't with the tubs either.
