how many guppies can i have in 20 gal

[bubleguppy_2013]

I just got a 20 gal and I had a 10gal with 8 males and a 5 gal with 3 females. If I keep my femals sep from males how many males can I keep in the 20?
I know if I join them ill have babies all over but If I join them ill let nature take it course.

A 20 gallon aquarium could hold at least 10 male guppies.

Even if I have good filter?

If you have a good filter you might get away with 20. I really would be afraid of overcrowding.

I would say about 15-17, if you had a good filter
