Which is better for a pet iguana, ball python, or frilled lizard

Frilled lizard.

Explanation:

The best option would probably be to keep them in separate tanks because reptiles are most of the time better alone.

I hope this helped! :)

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.
