>>While I'm still not sure what kind of geckos they are as I haven't actually seend them, let's assume they're med. geckos. Do you have any pictures of juveniles? The pictures you pointed out do not look like what was described to me, but your pictures are of adults.
Juveniles are similar though often more brightly colored (especially concerning the tail banding--it's black and white in juveniles but fades with age).
>>Assuming they are mediterraneans, what are the captive care requirements? Are they hardy? I assume they are by the way you talk about them taking over.
Captive care requirements can be generalized as the geckos are tolerant of a wide range of conditions. I kept some at 75-85 deg F, no lighting, things to hide under in a well-sealed enclosure (to prevent escapes), and misted the sides for drinking water. I fed 'em crickets; these might need the "small" crickets.
I live in Oklahoma so I know that we have winter days when the temperature drops into the teen and single digit temps. They can survive that?
Apparently so, albeit with Man's help--there is (was?) an established population living on the OU campus the last I heard/read.
>>Anyway, what about captive housing, care, feeding, etc.? Anything I should know?
On the off-chance they're not Med geckos, you might want to have your wife leave them where they are--they could be protected. I'm not familiar with LA law to know the particulars on reptile collecting (though it can't be too strict given their record of box turtle exportation!).
