Can someone tell me which are male and female Corys? Thanks in advance. Pictures in attachments.

The pictures are not clear, but the fish look very young. Did you just get them?

Yep. I got them 2 weeks ago.

The easy way to sex them is as adults the females will be larger with more girth (of course there are small females and larger males); conversely you could disect them and see if they have male or female body parts but this is usually fatal. I'm not aware of a way to sex young cory through observation or visual inspection.

When viewing from above, males are widest at the pectoral fins, while females are widest behind the pectoral fins.

Your fish are a bit young and thin, so it may not be 100%, but based off this Pic, I see 1 male and 4 females.

You can sex them by pelvic fin shape and sometimes dorsal fin shape as well, but i find it easier to sex them by proportions viewed from the top such as your photos.

Thank you. I will come back again after 3 months with another top view photo. You can see if you were right.
