Danios fish gender question

[Nina09]

Hai, i want to ask for my danios gender (pic attached). Can you tell me their gender please?
Number 4 i think its female, am i right? Before she looks thin but today i see her belly a bit show up.

Thank you

Number 4 is definitely a female.
Number 3 looks like a male.
Number 2 is probably female. If you can you post a picture showing them all together, it might be easier to tell.

#2 and #3 look like males to me. But #4 is definitely a female.

@Colin_T They swim so fast a bit hard take picture together with good quality picture. I'll try. Thank you for your answer.
@PheonixKingZ thank you for your answer.

Why number 4 chasing another big belly female often?

Danios do love to race around the tank

I agree with Colin_T. Female, male, female.
