I will try to make some reasonable courtship coloration pictures as soon as I have good enough equipment. My males show this very often but I only have a bad camera and when I tried to change the water so its clear or when you add strong enough light to be able to make pictures they become all pale so its worth nothing. They are simply spoiled I think :unsure:
These are by far the best pictures I was able to make so far :
but thats with very strong lighting right above the male and still its not enough light for the camera to capture it clear.
