How to tell a Male from a Female bangaii cardinal?


New member
I recently got a bangaii cardinal. I would like to get him/her a pair. How can I tell a male from a female? It's only a 22 gallon and has already a pair if clownfish, so I can't do the trio and see which 2 pair off.

you might try posting a good picture . It has to do with the lower jaw as I understand it. I don't know, I have tried. I can't tell the difference.
