Female Apistogramma alacrina (sp. rotpunkt) or not ?

I have a doubt on the sex ?

Any chance of more pictures of the fish? I can't see the ventral fins which would be VERY helpful as females will show a black leading edge to those fins.

Others pictures

We can't see on the pictures but the ventral fins show a black leading edge to those fins.

My guess is that your 'female' is a young male. Females rarely show and color on the face and the lateral band is almost always broken into a series of spots. My experience with A. cf. alacrina Rotpunkt is that 'sneaker males' are quite common when in with a dominant male. You could remove this fish to another tank and see if it develops into a male.

Hi ,​

​

I removed this fish to another tank and it would seem it develops into a female. Look pics :​

What do you think about ?

Probably a female, but could be a small/young/sneaker male. Time will tell.
