determining the sex of kribs

[dungeon]

I'm rethinking this now...

I've got 4, and I'm pretty sure it's 2 males and 2 females...

I've already moved the one I thought was a male to my Roma 240, so I've got 3 left in my Roma 200. Goal is to have a pair in each tank.

I thought this one was a male... It's been doing all the fancy stuff and digging up the substrate till now.

I've moved the other one that looks just like this to my Roma 240.

Then there are these two... They're different, not as colorful and no black spots on the dorsal fin.

The one that's really standing out with the bright colours, that's your female. She's got a more rounded belly and the colours are more vibrant. Males tend to be longer and slimmer, they don't usually get that red belly. Hopefully that clears things up for you.

Reconsidering, I'm now thinking I've got 4 ladies on my hands. Guess I was way off.

From what I've gathered so far, females tend to be shorter with rounded tails. They usually have bright colours on their belly. On the other hand, males are generally bigger, with longer dorsal and anal fins, and a more pointed tail. Not much colour on their belly, typically.
