i kept these a few years back,theres not much in the way of good info on them out there,but they are prolific stowaways and seem to do well wherever they end up,a friend of mine still has them running around a cricket room after some escaped in the mid 90s!,they have plenty of food but after 15 odd years i recon they must be seriously inbred,lol
i would suggest keeping them like anoles,with a cool and a warm side so they can regulate for themselves,they will use all the space you can afford to give them(small gecko dosnt neccicarily mean small viv)especialy if you accidently end up with 2 males as they arnt that easy to sex,apart from that all else i can say is they are display only (not to be handled)as they are deceivingly fast and professional escape artists,they can and will fit through tiny gaps so make sure to double check the viv
good luck
