Hey everyone, Just wanted to share how I set up my roach tubs. I set them all up the same way, have not had any problems, have never had to use a barrier, and the roaches have all been extremely prolific. My dubia population was exploding, so I gave the colony to a friend with a bearded dragon. I only have Lats right now but just set up a bin for some G. portentosa that I ordered. Lateralis bin on the right, G. portentosa bin on the left I used a Sterilite air tight bin for the hissers. S
