I loved my dubias. I wish I never would have sold themI am going to start a new colony soon.
They are a perfect feeder roach. I fed them to cresties, my tokay, leopard geckos..
They won't over run you though, they are a slower breeder. I wouldn't worry about that at all. They are also a much slower roach in general compared to others.
They love warmth, I kept mine at about 95 degrees. They love veggies, and roach diet too.
I got mine from blaberus.com. Great guy!
