Hi guys,
I have the similar problem with craniifers. Mines, by the way sometimes dying right after the last molt but I found many specimen dead with hardened exoskeleton. I keep them on room temperature with very good ventilation (same like other colonies) and they eat the very same food as the others. I give them cucumbers, apples, dried bun and dry cat food for protein. The substrate is aprox. 5 cm deep (barely 2 inches). It's a mix of coconut fiber and universal plant soil. They have nothing else in the 45 liter IKEA container. Every other colonies are absolutely fine. It is really embarrassing. I found an average 3-4 dead adults every day. I cannot find any parasites so I do not know what could be the problem. Their number is aprox. 200-300 maybe but I'm not sure. And the nymphs are fine too.
Can someone help me?

P.s.: I'm going to rehouse them without substrate so I can monitoring better dying. What do you think?
