Haha... I'm afraid he doesn't do the robot (even though I'm in the UK I've still seen the Geico thing on the net
)!
Edit: Sorry... we posted at the same time there!
Yes, I will be putting his little viv in storage for 'later use'! I have no space to put it once I get his bigger tank, but one day when I move out or something I can put some amazon milk frogs or some different arboreal geckos in it. Oooh... or pygmy chameleons. Heh - must stop thinking! All in good time

As with most geckos you can't keep two males together unless it's in like a huge walk-in enclosure where they can have their own territories etc., but even then it's not necesarily advisable.
You can keep breeding pairs of male and female, but from what I can gather I don't believe you can keep more than one female in with the male as even the females are very territorial and will fight quite aggressively with one another. There are species of day gecko that you can keep in small groups (such as
Phelsuma klemmeri) of females or one male to several females, but
Phelsuma m. grandis isn't one of them.
