Hello!
Now I found yesterday evening the female on the photos dead hanging under the swimming plants.
Today morning I made a water change and afterwards the next female (its my first tank where the first pair of phonicurus came in when I got them from Aquarium Dietzenbach, first 1.1 then 1.2) swam up to the water surface and is swimming there in front of the tank, and isn’t looking very healthy too.
Water parameters are: 4,7 pH, conductivity 18, Temp. 26°C.
I will load up some photos, I manage only two photos at once, so it will take about half an our till all photos are uploaded!
and here a photo of the two females on March, 26., 2015
