Fewer colour-types with the females? I am not sure (see 4.). And there are some spectacular specialities:
1. standard type one = individual without a mate courting: the mostly depicted state without “sexy eyes”.
2. standard type two = individual mated to a courting male: females with “sexy eyes” and very pale resp. yellowish (according to the species) body lacking the stripes. In some cases the otherwise clear dorsal and anal fins get coloured brownish or with dark markings (nagyi, filamentosus, alfredi, …).
3. affected by positive emotions = individual female aroused by aggression against rivalling female or troubling/annoying male but feeling dominant: intense colours especially of the fins, in some species even reminding (partly) of male (f.i. tweediei).
4. affected by negative emotions = individual female aroused by fear because of danger or feeling weak: may be identical with 1. or slightly different by speckled markings(?).
This does not apply to P. ornaticauda and P. parvulus. Females of ornaticauda change in heavy courtship their whole colouring to am appearance nearly similar to the male, including the “red flame” in the caudal. In parvulus many females tend to a similar change but by far not as extreme as ornaticauda.
Additionally, there is an aberrant variant of P. paludicola (probably a subspecies or species of its own), namly spec. Wakaf tapei. There, the females darken in heavy courtship instead of becoming lighter. This surely indicates a big difference to the normal colour change which is to be observed with other paludicola-variants, too.
But who shoots (good) photos of females? Nearly nobody. We lack them more than those of males. This is understandable, but it’s a gap nevertheless and we should try to fill it!
