Looks like something from the genus Leiocephalus, or the curly-tailed lizards.

Maybe Leiocephalus personatus, aka jeweled curly tail or masked curly tail?

I think the general care for these are relatively dry, sand and rocks, lots of light, high temps in the 90s, and don't let it get too cold at night (70s). And they eat bugs.

Maybe a 20 gallon long tank or larger for one specimen.
