I bought these Phoenix worms dishes and some worms for my son's bearded dragon recently. At first I thought that they were a little thin and might be probe to breaking easily. I'm not that gentle when handling the dishes and they have not broken. So they are better than expected. They contain the Phoenix worms and the mealworms I also feed our pet. Although, the mealworms are good little climbers and get get out of almost any feeder. By bearded dragon gobbles them up weather they are in the dish or not but I like the dish because it makes putting away whatever the pet isn't hungry for easier.
