Cory catfish

[Freddykruger]

Which one is male female?

 

[Gypsum]

Can't sex them from those photos (and I'm not brilliant at sexing them), but it's neither here nor there because they're two different species. Left looks like C. aeneus, and right looks like C. paleatus.

The left is a green cory and right is a pepper cory.
I got 2 more green cory but there still small

The bronze Cory looks nice and round I’d guess at female not sure , apparently corys do best in groups of the same kind so maybe boost there numbers a bit or pick the bronze or peppered, they interact better and will be a lot easier to spot the difference in yiur males and females watching them

You need big groups and then it becomes obvious, individual fish are almost impossible to sex
