Can anyone tell sexes of cardinal fish?

[opazen]

I want to get a breeding pair of bengaii cardinals but want to make absolute sure (or an educated guess) that I get a male and female. If ne1 has an Idea Im hoping to hear from you!

JW hits all the important points about sexing banggai not bengaii. I spell this correctly for you so you can do a websearch and get real hits, not to correct your spelling.
Bottom line is you really can't tell the --- of these fish, and if you try the group method of sexing make sure any fish which is cowering, hiding, or getting picked on gets removed immediately.
