I'm only new to keeping geckos so I can't give first hand advice but there is a book called keeping Australian geckos and the golden tailed geckos get mentioned in it. enclosure should be 600x300x400 high for one male and female or two females and provide some small diameter branches for climbing.
Hey thanks for the offer but i will have to pass, as im not 100% sure that i will be getting them now, as i have a 3ft tank and i think it will be too big for them.
