The Rankins Dragon is certainly more than a smaller version of the inland bearded dragon.  While the bearded dragon is a naturally a solitary animal, preferring to b
e housed in its own enclosure, Rankins are generally social lizards and seem to do better in small groups.  It is uncommon for Rankins to fight or injure each other, and they do not display the aggressive breeding behaviors that bearded dragons have, although just as in any species there are rare instances of dominant male behavior.  

The minimum housing requirement for a pair of Rankins is a 20 long enclosure, but they would likely be more comfortable in a 30 or 40 gallon breeder tank.  Unlike bearded dragons, Rankins are water loving and should have a water dish in their enclosure at all times.  If you make the water bowl large enough you may even find your Rankins taking an occasional swim!  They require a desert-strength UVB such as the ReptiSUN 10.0 linear tube or the Arcadia 12% linear tube.  Compact/coil UVBs are not recommended for Rankins, as the UVB quality and gradient is not sufficient.  Provide a bright basking light on the same side of the enclosure as the UVB, with a basking surface temperature of 95-100*F.   There should be a temperature gradient in the tank with a cool side temperature of approximately 75-80*F, which would be on the opposite end of the tank than the hot basking area.  Rankins are active and curious and do best when they can see outside of their home at the activity in the rest of the room.  The humidity in their enclosure should be measured with a digital hygrometer and should never go above 50% in order to prevent upper respiratory infections.  They should also be provided with a small, dark hide on the cool side so they can escape the heat of the day or sleep and get away from the lights.  

The average size of a full grown Rankins Dragon is approximately 10" long.  They are avid hunters and will chase crickets and roaches, but also enjoy soft bodied worms.  Due to their small size, they require small feeders!   A good rule of thumb is to keep the length of the feeder the same as the distance between their eyes, to prevent intestinal problems and impaction.  Good feeders for Rankins are dubia or discoid roaches, crickets, silkworms, butterworms, waxworms and small superworms.  They are omnivores and should also have some vegetable matter in their diet.  A good rule of thumb is to feed turnip greens, collard greens or mustard greens in the early morning, and protein feeders during the day.  Some Rankins will refuse to eat their greens if they were not raised eating them from babies, and this can be a struggle, but offer greens to them and often they will learn to eat them.
