For herps I've kept
snakes: mocquards, black king, leucistic texas rats, corns, eastern hognose, ball pythons, house snakes.
Turtle: Red Eared, ornate boxies
Lizards: Spiny iguanas, leos, cuban anole
These are the ones I can remember offhand. The corns are what began my fascination with morphs/mutations.
Now I find myself looking at water snakes/amphibians. Go figure!
