Well this aint no big lizards but still very active creatures

I think a meter long by 60cm wide and 40cm high cage will be more than enough for a male and 3 females. I think you shouldnt mix males. Their care aint gona be very diferent from lacertas

Rocks, sand and peat mix substrate, a few logs here and then, strong ligthing with basking spots and uv ligth(no heat during the nigth) and a few potted grasses and spineless suculents like Crassula. Their diet should be mostly insectivorus but Im shure they will also take dandilion flowers and ripe fruit. Pinky mice can also be very ocasionaly given
