Do pet stores sell fish sexes separately?

Do fish stores (like petco, petsmart, LFS) sell male and female fish separate? I have a 3 mollies and 4 platies in a 10 gallon. I don’t want these fish making babies because I will definitely not have enough room. Do pet stores usually sell livebearers genders separately?

The only livebearers I've seen them sell separately are guppies.
Mollies and platy genders are pretty easy to tell. If the anal fin is rounded it's a female, pointed and it's a male. For best results females have to outnumber the males.
Female livebearers can continuously breed a couple months after an encounter with a male.
10 gallons sounds a bit small if you have both genders (or larger mollies like lyretails).
Do you have a local fish store that could take in any unwanted babies? I think your best option would be to get a bigger tank or rehome the livebearers and get smaller fish.

Petsmart generally does. And there maybe a policy at Petco for selling males in one store of small animals and females at another store to keep them from breeding, but not too sure there are any others for fish specifically. My normal lfs I noticed sold Guppies by M and F in some varieties.

Yeah I do. The ones that aren’t eaten I’ll probably just give them to the pet store down my road. I did sex them and it appears I have males and females. Would’ve been nice for the stores to let me know this considering how many babies these things can have but it’s not a big deal. The majority, from what I’ve read, will just turn into fish food anyways
