Odessa Barbs - male or female

[CmdrX3]

Curious as to peoples opinion on sex. My wife is convinced they are all females due to their colouration, I'm mor of the opinion that some are male due to the shape and they haven't fully developed colour although i have to admit the last time I had them they coloured a lot quicker.

I’ve had a similar thing recently.Mine are now colored up.When I added 8 to my tank 6 were more streamlined in the body and 2 were more fuller boded like yours,which I thought were females.To my surprise they turned out to males.So you never know.They are spectacular when they are fully grown.

Interesting what happened to Moby's and they coloured up after a while.

I purchased mine young and the males was already showing their colour.

Yours do indeed look all female but i suppose you do really never know

How big are they?
They could be females or there might be some juvenile uncoloured males in there.

If you put them in cooler water for a month and then raise the temperature a couple of degrees, the males should colour up.

The light substrate doesn't help with colours.

Give them a few months to settle in and see what colour they go.

They are about 1.5cm -2cm in size

They are still babies and need a few more months to grow and colour up.
