Good Morning!
I just watched my quindecim displaying and took some photos which I would like to show. I find the courtship behaviour of quindecim rather interesting because it’s not only the male displaying his brightest colours in front of the female. In quindecim, the female “answers” the courting of the male by displaying herself. It’s sort of a back and forth: first he “flashes” in his brightest colours, fins spread, and moves sidewards towards her, while she moves backward looking at him in the same tempo he approaches her. Then she spreads her fins and moves sidewards towards him. First they display side by side, she moving in his direction and he drawing back in the same tempo, still displaying. Then he stops displaying and simply watches her displaying to him in the same way he did.
My rubrimontis and nagyi never show this sort of display of the female – I just watched in pahuensis, too.
Here are some pictures. I am afraid the tank is not very clean – the courtship behaviour always seems to be very successful, I have young quindecim of all sizes in this tank and thus am too afraid to clean it thoroughly. And the young seem to feel well underneath the leaf litter and fibres ……
