The older I get the more I appreciate...
I currently breed / raise various herps (specializing in ball pythons), rodents (domesticated varieties of rats, mice and African Soft Fur rats) and numerous different species of roaches.
As for cockroaches, I really enjoy all of the different hissers, Therea, Lucihormetica, Eurycotis, Gyna, Blaberus, Archimandrita, Simandoa and Macropanesthia to name just a few and am focusing on breeding / raising about 10 - 12 species at the moment. No Macropanesthia ...yet!... maybe someday.
Most recent book purchase 09/29/16: For the Love of Cockroaches: Husbandry, Biology, and History of Pet and Feeder Blattodea by Orin McMonigle - Highly recommended!
