Fading Colours On Molly

[Mammabe1]

Hello,

I had a big beautiful orange sailfin Molly and I noticed his bright colour was starting to fade on his body... 2 days later, I found
him dead.

My other Mollies and fish all seem fine. Anyone know what could have caused this? why his colour faded? No one else seems to have
any issues. Here are my tank details:

1. Water parameters. (ammonia, nitrate, nitrite, PH, temp', Hardness etc) > PH 8.0 / Ammonia .025ppm
2. A full description of the fishes symptoms > Colour fading - no other sign of illness
3. How often you do water changes and how much. > Once every 2 weeks, about 30%
4. Any chemicals and treatments you add to the water. > Only dechlorinator when adding new water and sometimes a little salt
5. What tank mates are in the tank. > 9 Mollies, 1 Albino Weather Loach, 3 Kuhli Loaches, 2 aquatic frogs, 1 clown loach
6. Tank size. > 75 Gallon
7. Finally Have you recently added any new fish? > No, not recently, all these tank mates have been together since April 2011.

Thank you!!
