I don't currently have my dubias with much for heating and they do fine. They have a slow growth rate. I bought 100 smaller nymphs almost 3 months ago and just have them sitting on top of my pacmans tank next to his lamp so they get a little extra heat off that during the day and a little bit of heat coming up from the tank at night. I've yet to have any reach adult size so I can't say whether or not they will breed at lower temps. When I first purchased them I had no intent on wanting them to breed but my frog collection is growing at about a frog a Month and need a replenishing food source. I am going to be putting them in a warmer bin soon.
