He is definitely a southern alligator lizard, as he has yellow eyes, and his markings most closely resemble the Oregon subspecies.

He seems to be doing ok; he finally got the courage up to climb and bask on the driftwood. But he still doesn't seem interested in the crickets or mealworms. I can't tell if he's eaten any crickets, since they hide, but he definitely hasn't touched the mealworms.

Should I be worried?

And does anyone know if I should get an undertank heater?
