I have been free breeding fancy guppies for about 5 years in a 30gl tank.I picked 5 color types 1 male for each 3 females plus a few extra for a total of 50 fish more/less. They do pretty much self regulate.dead of winter I'm down to between 30to50 by mid summer I may have as many as 300. I do pull off the red ones and the ones with bad shaped fins and bodys. The females will hold male sperm for close to 6 months before using it to drop new fry
 
Uumm I would need a calculator. But if you are like my neighbor - 500-1000 a year. If your like me and let nature decide maybe 30.
 
Do guppies go with goldfish? (If the gf's aren't big enough to eat the adult guppies?) The gf's would regulate the population and you'd still have guppies.

Here's some guppy math for you. If you don't have fish that eat their fry you end up with a mess in no time at all.

I had 6 in my 15 gallon in February. Now I have 100+. I'm waiting until they start to show their color before selecting those that will breed and those that are on the menu for the goldfish.

On a side note guppies make excellent specimens for studies in genetics.

it all depends if you seperate the fry from the parents so they dont get eaten. you could have several hundreds

I'm told guppies do not go with goldfish do to the need for a small amount of salt. As for the goldfish eating them not all goldfish will eat them. In the 30gl that I keep both gold/guppie.I have 2 GF one Big bubble eye and
Med size Lion's head,the lion head eats about one a month ,the bubble eye can care less about them
