I'll post a pic when I get home tonight of my colonies. I have lobsters mostly, but also a small colony of discoids. (the discoids can't climb glass) They are kept in large rubbermaid containers with a hole in the lid with a screen. The bug-stop or vaseline is spread around the inside of the top of the container and they can't crawl past. You can buy "roach food", but really they just need a high protein diet and will eat almost anything. I make a mixture of high protein dog food and non-medicated chicken mash, it's pretty cheap and lasts a long time. You can use any water cubes you use for crickets or apples for moisture. The adult roaches have wings on their backs, but they can't fly. I only feed the juveniles that look like big beetles, that way the adults continue to reproduce. The adult lobsters are about one inch, not very big. The discoids are much bigger, but I just feed the babies. It took a little getting used to, but now I have no problems handling them.
