A special advantage of the Mali uromastyx is that they are very sexually dimorphic. Males have jet black heads and tails with contrasting gold reticulations on the back, with gold front feet.
Some males have more gold on the back than others.
Some of the darker phases are especially robust. Mali uromastyx get very tame and are naturally an outgoing species. They adjust well to captivity. Furnish a hide box in the cage, and initially put their food right at its entrance, till they get used to their new environment. Usually they are good feeders.
