If you are referring to the little horned lizards that eat the harvester ants, I don't think so. The ants alone could pose a serious if not deadly health threat to the uros.
:Does anyone know if you can keep malis and horned lizards together. I know that horned lizards will not hurt the malis but will the mails bother them. I read that uros dont usually bother things smaller them. Let me know what you guys think. THanks in advance.
