My GABF almost eats as much as my dog. So I really need to start some sort of colony of some sorts. And with tons of research iv found that Dubia are my best option. I just have a few questions before I blow 50+ bucks on roaches and supplies.

1. How many should I get? I was thinking of getting 200 mixed sized Dubia, but is that enough? I can't find any info on GABF/roach colonies. Am I crazy for thinking 200 would be a good start?

2. What size tub will I need for such a big colony? For some reason I can't find any straight answers for this.

3. Can I add roaches over time? Like lets say I can only get 300 this time, could I add another 100 later on when I get paid?

And again, sorry I'm always asking questions. I really do check the internet as much as possible before asking.
