Too cute! I've got some little (wild) skinks in my yard, I love to see them rustling around, eating my bugs... I've never tried "keeping" any, but I've kept
other small lizards in the past, including desert "night" lizards (about 4" max. incl. tails) & a (native) banded gecko, etc.
When I lived in the desert (in the West, U.S.) someone gave me a local banded gecko, and one morning I found a night lizard (that had snuck into my
house) was sitting on the screen top of the gecko's cage, as if he wanted in? So I fixed him up a "castle" of his own- I don't think the banded would
have bothered him but you never know, and the night lizards are so tiny, they need smaller food anyway. Later, at work, I rescued a night lizard that our
custodian had swept up while cleaning the floors...these tiny lizards go unnoticed in the wild, living in fallen Joshua trees & such, but they're pretty easy
to keep (as I hope your skinks are too?) and so darn cute. Not a bit of aggression either, they seem almost curious about us "giants"...just way too small
to handle.
Sorry that you folks "over the pond" have to import your lizards...
