Hello! why is my mandarin discus changing color when the light is on?

Hello!

I have 2 mandarin discus who are a bit unusual as they have a white face. I guess that they are more red and white then mandarin properly. One of them (always the same one) is always bright red/orange in the AM when I light my tank and then the color slowly fades throughout the day....(!!!) to an almost pink/peach kind of color!!!! The other one does not change color at all. They are both about 4" and very healthy as far as I can tell. So, what's up????? Any idea??? I thought it could be the food, but they are all (I have 11 young discus in my tank) eating a very varied diet.... Any idea anyone??????

Thanks so much!!!

Hi Sophie,

It may be the breed of the fish that you have.... If they are Mandarin Passions they should not look as you describe...


Would it be possible to post a few pictures?

Hi Al,
Actually they are called Red diamond. I was told to not feed them anything with betacarotene in it because their face would turn neon red...So far, no sign of this. I have a film of the fish but I will take a pic and try to upload it for you. Thanks so much!!!
