Best tubs for breeding colubrids

Hello everyone! I have been away from the forums for quite a long time, but I recently started looking into making more racks for my snakes and was wondering what plastic tubs are the best (and most preferred) for breeding colubrids. I have used a variety in the past, but am looking to move all my animals into one consistent size/brand and want to find out what the best one is. Your opinions will be greatly appreciated!

What brand/model tub do you prefer and how much do you usually pay per container?

Thank you!

What type of colubrids?

The best tubs are Iris tubs as sterilite and rubbermaid are always changing their design. They are also easy to clean with their flat bottoms.

It really is up to you.
I use sterilites for all my animals, and they all like them fine.

Iris are good if you're building a rack because you can easily replace them. They don't change their sizes every few months like the other brands.

Also depends on what species you're referring too.
