I've been keeping my colony for about a year and half and they are all growing. I would like to vary their diet alittle more. What are you feeding your burrowing cockroaches ?
I can't afford to keep these (I'm assuming you're taking about Macropanesthia rhinoceros) but it's way cool that YOU keep them! Good luck with breeding these. If you get enough buyers and have enough babies, you could quit your job and sell these to make a living. Very cool!
You can feed them a variety of fruits and veggies, along with the dog/cat food and dead leaves. I have never kept this species, but I imagine a very varied diet is not needed. Still, I'm sure they would appreciate it. Good luck with your rhinos!
