Krib identification

[WogdenAB]

Please could somebody give me some advice. We purchased 2 Kribs from our local pet store but unsure whether they are male or female. Can any of you tell me? I can’t quite figure it out. To me they both look female but I’ve just noticed some holes appearing in the tank so it’s making me think I could have a male and a female. Thanks

I would guess male above, female below, but they’re very easy to sex. The pelvic fins of a male are long and pointed. The pelvic fins of a female are short and rounded. Have a look at some pictures online and compare the pelvic fins.
