Hello,
is there some pale red colour in the fins? If so, the fish reminds me of a not fully coloured P. spec. from Langgam. The slightly lanceolate caudal fin would also fit.
But of course, one can never be sure…
If you take a photo and use a flashlight, the red colouration of the fins should come out a little more.
P. spec. Langgam:
Of course Peter is right, that you should only use this male for breeding, if it is possible to get females of the same species (…from the same dealer).
Greetings
Martin
