Hello,

I have got some D. foirni wild caughts which were sold as 1/1.
Is this true and how can male and female be distiguished?
Here are some pics:

They look a bit young/small for positive sexing, at least for me. I think you have 2 choices: wait and see how they develop or, better if you can afford it, buy 4 more specimens - 2 larger and 2 smaller from the group.
