Ive never had copper and trigger go blind from treatment either but he did state both eyes are affected
Im just trying to connect the dots. These triggers took more than a year to a few years to go blind. I predicted a niger going blind after 2 copper treatments, he was blind in 6 months. A cause doesn't need to immediately happen to be a cause. I also asked if it were a binary contributor, something else already in the triggers system. I've seen it enough to question, and it's not like 100%, because one person has it and another does not, does not mean it is not a contributing factor. Seeing this is another reason prophylactic treatment with copper is again, just too high of a risk.
Hobbyist have this thing, if it doesn't happen right away, then whatever it was has no bearing on the end. They thing if the fish doesn't die or go blind while in the copper, that somehow the copper had no influence or their blindness or early demise.
