Neon Tetra problem

just for that one tank if thats the only tank they are getting fat when you feed them in, i would feed them every other day and see what that does.

fish can go every other day without eating its fine IMO just try that :p
 
in a nutshell I don't mean to sound terribly slow but how does cycling work? Theres no such thing as leaving the water just sit in the tank for the ammonia and nitrate levels to regulate, right? I'm confused.
