I split my Dubia colony into two, i now have one tank for nymphs and a tank for adults, its been just over a month now and I've had no nymphs from my adults at all. I feed them mostly apple, carrot and a protein supplement called "BugGrub" could the acidic diet be stopping them from breeding? they never touch cucumber when i put it in their tank, I recently started using water crystal gel(Like yesterday), will this help? any tips? Please help!
