He was referring to why place this in the other category, as it is about a mantid feeder it belongs in the Food and Feeding category.
A five gallon bucket would work, especially if you have a decent amount of substrate for the nymphs. Keep in mind though your colony can only grow to the size you offer so depending on how large of a colony you want, you might want to use a bigger bin. You also need to make sure whatever you use is tight fitting. The adults can climb/fly and the boys especially are very lithe and can fit through tiny spots. This isn't a species you need to worry about infesting your home, but it's not good if your colony members keep wandering off. :stuart:
If you have a cleanup crew with spiringtails/isopods/ect and the like you don't really need to worry about cleaning. I've had my colony for about a year and all I do is till the soil occasionally and every so often add a bit more. The nymphs spend most of the time underneath the soil. I wouldn't bother with a seperate container within the bucket to hold the soil as that will just make things more difficult when you end up with adults trying to wedge themselves between the container and bucket walls. You also loose valuable usable space for the nymphs. I would simply fill the bucket halfway up with whatever substrate you prefer to use.
