black skirt tetra gender

[HoldenOn]

Hey all,
How do I sex my black skirts? I know females generally need more space and want to figure out my ratio. Don't worry I won't throw a gender reveal party .

post a picture showing all the fish and we can try to sex them.

Should I let them mature a little? I think I got two shipments because 4 are a lot bigger than the other 4.

Dorsal fin in males is slightly more pointed.

When viewed from face on-- females are pear shaped while males are slim.

The pelvic skirt also tends to be more rounded in females
