Not a mystery fish but a mystery gender #1
Hey
I am trying to rehome a small group of young paradise fish that survived being eaten by their parents in a tank at my work. I'd like to keep a male and female pair in my own tank but am having trouble coming to a conclusion as to what gender they are. All of the fish look very similar to me apart from one who has much more elongated fins. I have attached pictures to my post. Any help would be appreciate.
Thanks in advance

Here is the one who looks different and one of the other who all look just the same apart from size.

Re: Not a mystery fish but a mystery gender #3
To my eye, the fish at the back in the first picture you posted looks male with the one in front a female. In your follow up post it looks like the top one is female and the more blurry pic below is male. If juveniles though it may not be clear at the moment.

It is possible for a spawn to be heavily weighted towards one gender as water parameters at the time of breeding can influence the gender of the fry.

I concur with fishlady.

Rounded dorsal- Female
Pointed dorsal- Male

Re: Not a mystery fish but a mystery gender #5
Thanks for your help. That was what I was thinking too and is probably best as have a few people who have said they would take a pair of female. Thanks again
