Hissers are said to breed at the same rate as dubia. This means they berth once every 2 months between 20-40 babies. the only differences is they mature into adults in 3 months, this is twice as fast as dubia making their population grow twice as fast. They are kept quite similar to dubia. Similar heat and humidity and husbandry in fact you can keep both species together successfully. Oranges also improve breeding with this species.
3 months? That is not true. With me it takes around 6-12 months in my experience. And my roaches are kept very warm and eat a lot.
