Hi Rafael!
Your photos show definitly the two female! They are also quite nice coloured, but if you see the male in comparation, the difference is clear. The male has even longer fins and is blue or black, when he is in the mood, coloured, and has a blue spot on the side, the female have just a black spot there. I have some photographs in “my young linkei” …
You could look in the tank (take the plants and the cave outside (you should first under water control if he is not already breeding in the cave!) so you will find out if he is still alive!
My male phoenicurus was long time not to be seen, I have described that in Bernds thread asking about offspring. So I looked for him (didnt find him) but the first little offspring …
Nowadays I see him from time to time.
In the other way it´s possible that a fish doesnt survive the stress of transporting to a new home, but I did´nt experience that before … but you cannot be 100% shure …
