One can stay in a 10 gallon, but for multiple lizard I suggest something like a 20 gallon long or a 29 gallon. They seem to run around really fast and would appreaceate a large enclosure. I notice they like to bury themselves in the substrate, so provide it with bed-a-beast of clean potting soil with no perlite and fertilizer. I had mine I fed them everyday medium size crickets or several of the small ones. They have a really active metabolism if kept at a proper temperature and should be fed everyday especially growing babies and juveniles. Temperature at the basking around 92-95 degree with the cool side around 80 degree seems to work well dependant of where the lizard comes from. If they are from the desert and basking area reach 100-102 degree should be provided with cool size for the lizard if it wants to cool down. This is why large enclosure is necessary...to provide proper temperature gradient. I don't think they drink from a bowl and get most of the moisture from the food they eat, but I do mist them and they lap up some water. I hope this help you out a bit.
