Cohabitation for Periplaneta venom?

[Kaiko]

I’m finally preparing a decent enclosure for my Venoms and was wondering if there’s anything else I can put in their enclosure (other roaches species, isopods, etc) besides springtails.

The problem is Periplaneta are just too prolific and too protein hungry to be good tankmates for much else. I think some have had success with Porcellionides pruinosus as CUCs for these, and of course springtails. But other roaches will probably just be eaten by the Periplaneta. You can find videos of Periplaneta americana online attacking and eating live crickets.
