If this fish is 2"/5cm+, then I would say that it is a female. If it is <1.5"/3.5cm, then it could be a young male.

It appears to be a female judging by the girth, finnage & the dark spot(s) in the dorsal...

Hi Mike, Viejo

Thanks for your responses, from which I am deducing the fish is female.

As you can see from the picture updates below, it is colouring up nicely. However, the second picture will show that it is very plump around the tummy. Is this normal, does it have a health problem or a genetic problem?

Thanks

In curviceps the females appear more 'chunky' while the males are longer & thinner. The top photo looks like a male in many respects. The shape of the genital papilla, however, indicates that it is a female. See how hard these little fish are to sex?

As far as I know the only way to be sure is to pick them up and look at the sex.

I have three individuals in my tank. One is a sure female cause she lays eggs. Her mate I am more unsure about. Looks like a male, but no eggs gets firtilized, and the third is is a male cause I have hade a close look in his ass :)

I wonder if I can have a pair of lesbians if I have a male for free, anybody experienced this?

Sadly I cannot catch the "pair" cause the tank is to big and well planted.

I have a pair of L. Curviceps

Bought as a male and female.

I cant get our timing right to get pics of them....


ONE has two black spots in its dorsal maybe above its butt
ONE does NOT have these definitive black spots on its dorsal.

They were grey and black when I bought them, since then they have changed to grey,black,blue,yellow and a outline of red on the fins.

Thanks In advance for your help.

Spots and color have nothing to do with sexing curviceps. Body shape and the shape of the genital papilla are the best ways to sex this species.
