How to Sex Banggai Cardinals

[Struggler]

Thinking about getting some Banggai Cardinals and see if I can breed them for fun. How do I know if they are male or female when I head to my lfs. Thanks!

It is really hard to do when they are small, like what you usually see at the LFS, but they have these teeny tiny protrusions near their anal fins. Females have 1 and males have 2. Let me see if I can dig up the article I read a while back on this subject.

Edit: here ya go.

It was the first thing to pop up on Google, so I didn't really have to dig for it lol
