Yeah, I have 11 gila monsters and 6 Mexican beaded lizards. Soon I'll have 17 beaded lizards. Eggs should hatch near the end of next month or early January. Gila monsters don't need much room, so a big enclosure isn't really needed. They spend 90% of their lives underground in a small burrow and only come out to eat and mate. They don't even eat frequently in the wild. They may only eat a couple large meals the entire year. I feed mine once a week just to fatten them up prior to the 4 month brumation in preparation for breeding. They don't eat during brumation, they just sleep in a 50-55°F room with no light.
The beaded lizards need more room so I have 100-210 gallon aquariums for the bigger lizards.
