I think he is a mediteranian gecko
I think he is, too. Med gex are common in the larger cities throughout the southern US now. They started after being introduced on both coasts and worked their way inland.
Did you catch it in your yard? If so, you can release it. Maybe he'll make it, maybe not (due to cats or other predators) but the local population will survive either way.
I've observed baby med geckos eating ants before, so those should be acceptable. That thing will probably try to eat anything smaller than its head and soft enough to crush in its jaws.
