2 colonies- both in about 40 liter tubs.
Dubia colony about 300 adults, 500 medium, and 500 nymphs-small. Rough estimate- I'd say about 4-5 pounds total.
Orange head colony is about 1/3rd that size, same container.
I know the little ones need some frass.
There is no substrate and I use 4 pack coffee cup holders from the convenience store for them to climb on. Each colony has about 6 of these egg crate type things (I like them better than egg crates because there are holes for better airflow.
