Allpet Roaches

I asked because they seem to have a larger and wider appetite than those species and could possibly work better for your purposes.

Nice to have you! Did you try Gromphadorhina portentosa?

Some Eleodes larvae eat other Eleodes so you may just end up with one species.

Welcome! What about the giant green banana roach?

To clarify, the latest I-M issue has a pic of a beetle trying to mate with the author's finger. I do not believe any hyrids were created.

It would be neat to see what a cross looked like, but attempted mating does not mean fertilization.

The males are very small compared to females and mature faster, so if the little ones are males they might all mature at the same time.

You can check the gender on older nymphs with the segments, but if these are pretty small it may not be obvious. Do they all look like males or all females? The female nymphs grow a lot larger than the male nymphs due to the difference in the adult size.

Just make sure you don't use buffalo or dermestid beetles, they eat the roaches in quantity when their populations explode.

Adults will eat very tiny babies under some conditions but a big one getting eaten is unheard of.

Welcome! I'd suggest G. oblongonota, G. "princisia big" and Macropanesthia. I think I have flexivitta still listed on my last list. I originally got into roaches because you could find them for sale a long time ago (it could take you a decade to find ten different species) but nobody bred beetles and you certainly couldn't find them at a pet shop.

Welcome oblongonotaFan32! I still mostly prefer the flashy stuff.

N. cinerea has been known as the lobster roach since at least the 1980s, flexivitta is named after it because it looks similar but bigger.

Trigoniulus corallinus and Anadenobolus monilicornis were established by agriculture. Those are tiny, unimpressive species that were never kept or heard of before they plagued Florida after introduction with ornamental plants. There are NO species introduced by the hobby. Millipedes were not regulated prior to 2006 and were still being imported legally.

What kind of info are you looking for? If you're looking for something that adds to your background knowledge of roaches it's great. It contains a lot of interesting facts about cockroaches but it is a discussion of biology tidbits (not husbandry related) often about species you may never see.
