Like John said Blaptica Dubia are a good roach.
The only regret I have with these roaches was not initially buying more. They only problem I've had so far is a lack of babies. Compared to lobsters and Turkestan roaches these guys breed slow.
I've had mine 2 months now and I haven't seen any young. However I did find 2 dropped oothecas.
They're are others though I've read that the Orange Head Roach. Breeds faster than dubia and others like it. They can't climb glass or smooth sides. I've read they do have a strong defense odor
