I only just saw your original post and your more recent ones.
I too have had discus with what looks like a shredded fin. The most pronounced was my Marlboro Red. He had it by the time he was about 5 months old. I just finally accepted it as normal for him. It didn't affect his offspring. It is also possible that any who inherited the mutation were ones that I culled so I never noticed it.
All of the now adult offspring who live near enough to me for me to visit them have normal pectoral fins.
I know that doesn't help with your beautiful calico with the splayed pectoral fin, but hopefully you can now breathe a little easier and know that it's a natural mutation and not worry about it or try to cure it.
Coming in a little late on this one but Israel, can you tell me your water parameters?

Hi Al,
My water parameters are:
This is around 1000 Liters system (5x2x3ft tank with 4*2*1 ft Sump), Temperature 84 F, total dissolved salts out of tap is 100 ppm, PH is 7.2. I perform WC once weekly 80 percent.
Please note that this Calico Discus I bought recently hoping the damage on fins was going to be an issue to recover with good food and water. Until I discovered that the trim did not fixed the issue, i talked with a Singaporean Breeder which told me he has experienced this on fish before . He classifies this as genetic defect.
After 12 days of experiment, I have observed the fin is growing back with thew same shredded aspect. Talking to a local breeder here in Singapore he told me this is one genetic defect he has encountered before.
First picture you can see the trimmed side. Second picture you can see how the other untreated fin looks. I will post update after a week to see progress on trimmed pectoral fin
Very interesting thread. I have a discus with nearly complete shredded pectoral fins. I decided to give it a try on one side to remove the damaged parts. Motivated by seeing the nice recovery progress on that beautiful heckel.
I comment my results once i see progress .
Amazing job Brewmaster. I for one would of done this several years ago on one of my Red Terrors that had been busted up in breeding. I always thought that IF the Dept. of Conservation in Illinois did this to fish they released into lake to be able to tell which year the fish were put into the lake during their yearly fish counts. They would trim different fins on different years and then use that to differentiate which year and how much growth since introduction. Several years later we still see fish that have trimmed fins. So that was my reason to never attempt this on my own.
Next time I just may.
