you talked me into it lol...ill have to research them and see what all id need for them but i want one now

How many would you suggest 1 or 2??
which type? geckos like this? there are a ton of species of geckos out there. These (crested geckos) and Leopard geckos (like my leo and freddy) are the best for starters.
really, If you're new to them, get one. They do not need the company of another animal, and are perfectly fine alone. if you get two, there's a chance they'll be male & female in which case they WILL breed, or you could end up with two males, in chich case they WILL fight and possibly kill one another.
you cannot tell the sex of a baby gecko, no matter what anyone tells you. they do not develop sex organs until maturity which is about 1y. some people will be able to make an educateed guess, but it's never 100% sure.
they really are amazing creatures. if you have any questions about them, feel free to PM me. =]
