I just bought 2 six month old viper geckos, and i don't know how often to feed them and how much, if anyone knows can you tell me, thanksin advance.

Shame on you for not at bare minimum finding a care sheet before acquiring animals. I found some for you:

www.homegrownherps.com/Care Sheets Pages/viper.htm

Without having read those myself, I'd guess that their feeding schedule would be similar to leopard geckos - daily for juveniles tapering off to every 3 days or so for adults. Juveniles probably get as many appropriately sized crickets as they'll eat, adults probably won't eat more than a few per feeding. That said, I haven't thoroughly researched viper geckos, so please read the care sheets I found for you - they'll be more accurate than me.

Thank you very much,

By the way i was just getting a second opinion on how often to feed them, the petstore owner- friend alredy told me but he didn't know much about them,and i spent the past two days looking through care sheets but they never mentioned how often or how much to feed them.

In that case, I guess I owe you a bit of an apology. I just tend to go a little nuts when people buy animals without finding out how to take care of them first. I really feel like when you get a new pet, it's your responsibility to know how to take care of it and give it the best life you can, and that's obviously impossible if you don't do any research first. Sounds like you at least had somewhat of an idea what you were doing, which, while not necessarily great, is a lot better than what I thought your situation was based on your initial post.
