| HI Dick,
your comment about the red deteriating without natural light got my attention,
i have a section that is closed in withought my natural daylight and the fish go from red to orange very quickly, i too blamed the lack of naural light for this but now im not so sure...why?
well when the koi are in there the temps are usally quite a bit higher and the fish grow quite a bit faster, so perhaps the fading is just the red stretching, the koi also feature the darker red slit through the scale indicating the true colour of the fish when the fish growth slows down, i thought that if it was a genuine deteriation of the red then the dark red slit that you see on growing koi would not be there?
however its interesting to note that i had some fry where the red was so faded it was actually dissapearing and when put outside the red became stong again withing a few weeks?
so perhaps the colour does indeed fade and i need a more controlled setup to test the theory. any other experences of colour fading relating to natural light?
