I'm interested in these little geckos (Stenodactylus petrii, Stenodactylus doraie and Stenodactylus sthenodactylus) and would greatly appreciate some info. First and foremost, does anyone know the average lifespan of these geckos? Second, could you fit 1 or 2 in a 30cm x 30cm x 30cm Exo Terra terrarium? If not, what size would you recommend? And other general care information would be great thanks, hopefully my mum will give in to me nagging...although thats unlikely while my hamsters are still alive and kicking (which they, unfortunately, may not be for very long).
