Hi Rameez

1) Pigeon Discus will always show peppering at one point. It changes with their mood, stress and even a dark substrate and/or background will cause it. There are some things you can do to avoid it...keep the water clean, change or install a light colored background.

2) The only species that show pepper is the Pigeon species. All the other species of Discus have bars which come and go according to the mood and stress level.

3) DO NOT alter the pH of your tank. A stable pH of 8 is much better than a fluctuating pH. Discus will be just fine in a pH of 8 as long as it is stable. I also do not recommend changing 50% of the water every 2 days.

Hope this helps, good luck!

I own and maintain several freshwater aquariums from 2 to 180 gallon. I can answer most questions about freshwater aquariums, including setup, cycling, maintenance, compatible tank mates, feeding. Moving? I've moved fish both across town and across the country and can help you get your little aquatic friends to their new home safely. I know and have experience with most freshwater community fish, South American Cichlids and African Cichlids. I don't answer questions about Goldfish or keeping Goldfish with Tropical Fish. I also don't answer questions about keeping crustaceans (shrimp, snails, crabs etc) with Tropical Fish, nor questions about saltwater fish or aquariums. I'm not available to answer questions on weekends, this is when I do maintenance on my own tanks.


Many years of personal experience with community tank fish, semi-aggressive fish (Barbs, Tetras, etc), Angels, South American Cichlids and African Cichlids.
