I'd say that as a newbie, I could hardly resist stocking right away. The infamous 'nitrogen cycle' seems to take forever!
My 6 pearl danios survived it alright, but with almost daily water changes - and the cycle still took almost 6 weeks.
My advice; take your time and try to ignore the tank while it's cycling. It's better to wait and have the fish you want to actually survive than it is to get frustrated and try to add way too many goldfish or the like.
2nd point of advice - read EVERYTHING you can find, be it here, @ google.com, or @ the library. There is no such thing as too much knowledge - especially when the caretaking of life if involved!
