Male or female?

[Mikemeets]

How can a person tell what is a male or female? Head shape or fin shape? I cant tell diff so if anybody got pics and can see the diff from male to female please post a pic :D

The only true way is to observe the breeding tubes. The female tube is larger then the males and squared off at the tip. The male is smaller with a rounder, pointy tip. Generally fish will drop their tubes shortly before spawning.
