Every 3-4 months the bottom breeding tub gets sorted. All the babies go to the top and each tub moves down one slot.

This gives me a breeding tub and 3 sorted sizes.

My t-stat is set to around 98, the bottom of the tub is about 95ish a small gradient to the top so they can self regulate some.

I give them a very mixed diet. Throw in some fresh produce when I have it.

So far I'm really happy with this set up and works well for my needs.
