How old do guppies usually need to be before I can tell what sex they are? Do I just figure it out by their tail or is there some other way? I think for the time being until I can get more tanks set up I am going to try and keep only the males but in a seperate tank since they are prettier since the tank would be in plain view in my house.

Some people say they can sex them when there a few days to a week old but i think the majority say about 3-4 weeks,I had a hard time doing it even when mine were just over a month.
I have gotten better now!!!took some time.
The females will have a visible dark spot (gravid spot) at the back of their belly,this is easier for me to find first.
If you do a search on the forum for " sexing fry " you'll find lots of info and i think a few pics of what to look for.

100 gallon - Gerbils
1 55 gallon - Apistogramma & Cichlids
1 55 gallon - Dwarf Kribs (i think,since they never grew)
29 gallon - Breeding pair of Kribs and new babies
20 gallon - Yellow Tiger Endler females and 1 male California Tiger Endler
1 10 gallon - Mix of guppies and endlers
2 tanks not in use as well
I can usually see a gravid spot around 1-2 weeks of age. I would suggest removing the ones you KNOW are female rather than removing the males. It's not as bad to get one female mixed in with the males as it would be to get one male mixed in with the females.
When in doubt do a partial water change
If she's been exposed to a male I give a 99% guarantee that she will have her babies within the next 35 days....next question?

Better to go by the gonopodium... that usually starts to form within 10-21 days. Sometimes IF you know who the parents are (and they are HB strain) and the male fry have good color at birth, you might be able to seperate m/f almost from the time she drops. Female fry at birth are usually colorless.
Hey Kimo, your in Arlington? I am too!
Well all of mine look pretty much colorless, but they were also born on the 22nd and the 27th. I am getting a 10gal setup for fry only. I will try and figure out the sex thing in a couple more weeks. Thanks for your help everyone!

I use a small clear glass and a magnifing glass
At the age of 30-35 days the sexes can be distinguished by the development of larger body of the female and her gravid spot which males do not show. The male begins to show the developing gonopodium.
Did you do your water change today
