this is quite hard to do considering there are hundereds of breeds of geckos but they arent big they dont need alot of feeding and most are pretty calm if handled often fat tailed geckos and lepord geckos are probably the most common geckos and they are great i have a fat tailed and it is very very calm the only downfall is there nocturnel but in summer i find mine comes out alot more often but if you want a gecko that is out alot all year round then id reccomend the maddagascan day gecko they are very very active but alot of them are very scittish .
