How to sex bichirs?

Any ideas?

A male polypterus typically has a longer, wider and more protruding anal fin than the female polypterus. An adult male polypterus will also occasionally 'flex' his anal fin whereas a female will not and cannot.

Agreed. You will have to wait probably around a year to know.
