I thought about the size variances. I think for now I will just want to get the stock up then start changing bins every 2 weeks. I think that will be easier with the setup I have now. When I'm swarmed with beetles I can start changing bins. I got the deeper tubs so I can have more mealworm/superworms. Wasn't thinking about how the beetles won't really go that far down in their food. A longer wider surface area tub would be good for the beetles. Thanks alot, for now until I get my stock up this will do. I didn't order the mealworms/superworms yet. I'll definitely order more superworms than mealworms.
