I have P. sicula in a 30 gallon tank. Haven't had any breeding success, which I suspect is due to the fact that I can't brumate my lizards (no room to have a cold room in my place). A friend in CA kept his P. sicula in a screen house outside and he's been inundated with babies.

P. sicula are a very interesting and charming pet. Mine, particularly the girls, have learned to recognize me and come running to the front of the tank when I draw near. Don't mix them with other species, however. They are very aggressive between themselves and absolutely toward other species.
