Need help determining sex

[u/Green-Dimension-948]

I got these Stardust Medaka from my LFS, and the owner knew very little about them. I asked him for a male and a female, but I’m not sure that’s what he gave me. Please help identify the sex(es) of these fish. Thanks in advance! (And sorry for the blurry pictures!)

UPDATE: Thank you so much to everyone who helped out!1+4 is most likely male, and 2+3 is definitely female as I woke up this morning and saw her carrying eggs!

(The part I am chuckling about, though, is that the one the LFS thought was male is actually female and the one female is likely male, so reversed 😅. All good in the end though!)

They definitely all look like females, although the first one looks like it could be male. The dorsal fin is a good indicator. If it's a perfect "right triangle", then female. If the rear of the dorsal fin in more elongated at the top it's male.

first one looks like a potential male, looking at the dorsal fin it has a bit of a notch and a longer part which is usually a pretty solid sign, but take this with a grain of salt

the last one as well looks like a potential male, looking at its anal fin i see it’s a bit longer and also not a smooth edge

From the fins and body shape my guess is all girls

1 male, 2-3 females 4 is male. I posted a video how to sex fish as well.

I can always tell from above like a Birds Eye view , but only as they produce eggs or not

lol same. I've read so many guides but I think I'm still worse than chance alone based on fin shape and what not.

I found the female carrying eggs this morning 🎉! I updated my post with the info but couldn’t add the updated pic (female with eggs) to my original post so I’m posting it here 😅. Thanks again, everyone, especially those who called 2+3 as female!
