Tanks are just a pain to deal with. I'm switching my Cresties and millipedes over to tubs soon also.

Petrie(snake) has already escaped from his tank once, even though I have the slide in lid with the locks, I have no clue how it happened and I don't want it happening again!

I think they would be lighter and easier to clean, and just all around better.

It's a 20 L with a divider in the middle and I just think it would be easier to use a tub right now and maybe put him back in the 20L when he's an adult, or maybe just move him into a bigger tub.
