Ive always done it. Zoos do it. If you understand the behaviors and tendencies of a species it is acceptable. Scrubs are largely immune to parasites, both internal and external and do not prey on cold blooded animals. Also, early cohabitation is a breeding strategy. The animals have to know and essentially like each other to breed, especially in hybriding. I intend on separating them around the breedin season while they are still too young to breed, but they will be put back together for the remainder of the year. In my mind, as long as you monitor the animals DAILY there is minimal risk of health problems or injury. I understand many of you guys have tons of individual animals and daily care is nearlly impossible, but my tiny collection affords the animals a greater degree of special treatment. Heres to the individual! thanks for responding, Jason
