well i would like to become a breeder myself in the near future so i want to fine out about it .
People want good quality joeys from someone that can give them advice, you have admitted you know nothing about them, so how can you offer advice to someone that also knows nothing about gliders? Knowledge comes with experience.
For example, as an ex breeder, I wouldn't have sold a lone glider, one of the most basic requirements is for them to have company. so whoever you got him from could have just condemned that glider to a miserable life of solitude, is that because s/he didn't know any better or becuase s/he didn't care? Fortunately you are looking for another glider to put with him, but please give it a year or so before you start breeding. Give yourself time to enjoy suggie parenthood without the stress of breeding. Get him neutered and find a female, you can then get an intact male later down the line.
I'm sorry if I sound harsh, but there are already enough breeders out there giving poor advice. Please, please, please, be one of the good ones and wait for a while.
