My cranwelli (about 3 inches) seems to ignore adult blatta lateralis (Turkestan Roaches). Even when the feeder is just in front of it. It eats goldfish, and superworms. But I don't want to make them the staple diet of my pacman. Superworms' hard exoskeleton (even if it contains less chitin than the mealworms') is hard to digest if fed frequently and in large volume.Goldfish, some say, has parasite. Better to be safe than sorry.
Is there any issues about pacman and roaches?
