I don't think you will find any care sheets for them but they are a reasonably hardy species and would have the same requirements as the bigger lacertids. Try looking up care sheets for eyed lizards, Balken green lizards and green lizards.
I agree with natrix.
These are also on the EPS i believe.
With reguards to keeping and housing them, they are extremely hardy and simple to keep
I used to catch,keep,rear and even breed these as a kid in france.
sorry its a crappy picture, its very old and only first ones i found to scan in, here some of the babies i bred years ago
