Ahoy! I'm new to the board and new to the centipede world. I've had millipedes and madagascar hissing beetles for many years living together in a 40 gal tank. I got the centipede to naturally keep my roach numbers down. He is in his own 10 gal tank with 4" of substrate (ecoearth: shreaded coconut) i have a red heat lamp and a heating pad on the wall at one end of the tank. My centipede is about 6" right now and im curious as to if the 2" long hissing roaches may be to big to feed it. Anyone else who may use the same? I'd love some input. Thanks folks.
