Hi, Bartian,
I think you might be right – at least in it most likely not being P. anjunganensis.
As I understand and one can see on pictures, anjunganensis has completely plain coloured fins with only a whitish or blueish seam.
I think, at least one of my fish is developing a pattern in it’s fins, even the tail fin shows very delicate markings:
I am sure of at least two of my fish being males – one of the bigger (see picture) and one of the smaller ones. I believe the other bigger one to be female, but am not completely sure. It shows no pattern in the tail fin and answers approaches of the males with keeping it’s fins tight and slowly moving away, head down.
The two fish I believe to be males have already inspected the clay tubes several times.
