I used to offer that stuff to my dubias... but one day my little cousin was bored and stole a large female, killed her (hes 8, and kind of sadistic), and cut her in half. I admit Im glad cause what we found in her abdomen was REALLY DISTURBING. She was FULL OF GEL CRYSTALS!!! I mean like she was a stuffed beanbag.. only with gel... i was shocked and immediately concerned because I dont know if that stuff is safe to EAT... and my dragons were eating those things too. so I stopped offering it and switched over to just misting the roach tub. its been a few months and they are doing very well.
