Consequently, internal tissues are effected and would guess this might cause the red streaks. Maybe dont feed for a bit, especially high protein feed.
what is the pH? i know it's borderline anethema to the prevailing opinions on this site but might suggest to attempt to slowly lower the pH to further reduce the toxic NH3. Lowering temperature can also help but to a lesser degree.
Best to just add prime and change water as prime detoxs ammonia completely as well as nitrite and nitrate which is a better solution than just trying to lower the pH to increase the ammonium/ammonia ratio.
