Either a single gecko of either gender or two females would be the best, they're semi-solitary creatures so don't mind being housed alone if you were to get just the one. A male and female combination could work but you would need a second viv in order to seperate them to prevent over breeding as the male will mate with the female, and as she would be the only one, he would focus all his attention on her.

A 3 foot viv will do fine for 2 and would be nice and spacious for 1 too. My gecko loves to bask on rocks, these would be nice to place in the tank for your gecko(s) too. They need a hide on the cool end, and a hide on the warm end. The hide on the warm end should be the humid hide to aid in shedding, if you are getting 2, an extra hide would be nice.

For substrate i recommened reptile cage carpet, avoid using sand as it can cause very serious problems!

Good luck with your gecko(s)
