Large guppy

[Kevin1962]

I received this girl with a group of fish that were to be discarded last September. She's 2.25+ inches long, very healthy and active. I'm confident she's a guppy and would like to find a male of her species. All I see are males of similar colouration which are an inch at most.
Anyone willing to point me in the correct direction or clue me in to what she is will have my gratitude.
Cheers!

Ah. A blurb on guppies pointed me to Sunrise, and she's almost certainly one.
The care sheet said they get to 1.75 inches and the females are larger. Used my tape measure and she's 2 5/8 inches long.
Now to search for a male and at least 1 more female.

Wow I’m a little late to reply but if you haven’t already bought another guppy or something I would suggest getting 2 more females, and if you want babies a male as well.
Guppies should have a 1 male to 3 females ratio to be at their happiest. Keep in mind you’ll probably get a lot of fry though.

Although I might also add from the picture she looks male to me simply because I can’t see a gravid spot but it’s probably just the photo.

if you are looking to get fry of the same colorationy ou may not get 100% same coloration since you don't know where its from and the line may not be pure.

Not all females have a gravid spot. Females can be detected 100% by their analfin. If its a fan shape its female. If its a thin stick its male.

All females have a gravid spot, its just you cannot always see them in a darker colored female. The analfin thing will only work with developing males or mature fish - late blooming fish like swordtails can pass as female much longer than a regular male.
Look for the gravid spot always, otherwise you might end up with a male that hasn't yet displayed he is truly a male.

Unfortunately even gravid spot isn't foolproof with swordtails. Can see from pics in this post, one of mine clearly had a developing gonopodium while also having a definite gravid spot:

Best way I've found to tell with the swordtails is by lack of offspring, and/or by lack of mating/courtship from an otherwise active resident male. Experienced males seem to know well before it's evident to us, and won't waste any time on them. The resident stud in the tank with this transitional/late-developer just ignored 'her' completely, until 'she' transitioned.

Guppies do seem to be a lot more straightforward, I can't recall ever having any 'surprise!' males with them once they'd reached an adult size. Their lives (normal lifespans) are shorter, so they probably don't have the luxury of delaying sexual maturity/reproduction in order to gain body size like swords do.
