Im currently keeping a small colonie of Gromphadorhina portentosa (madagascar Hissers), another small colony of Blaberus discoidalis (discoid roach) and a large colony of B. dubia for feeders. all i have to say is i love my roaches, their fun to play with, and easy to care for. Im not familuar with anyone keeping C. Punctulatus, ive actually never even heard of/ seen in the hobbie...
