What is wrong with my V Bifa lip?

[NOLAGT]

Tank looks over crowded. Your fishes skin is being irritated by bad water quality. If you havent disconnected your filters when treating this tank for parasites you most likely wiped out the beneficial bacteria residing within. An easy way to stop the puffy growths on your fishes flanks is keeping the PH well over 7, and 70% weekly water changes. When water is being returned to your tank make sure to have it bounce off a rock or wood. This helps displace the chlorine which benefits the fish when doing large water changes. No chemicals are needed. Just use kosher salt for the first few water changes and reduce the amount of food used when feeding. This will allow the bacteria to build up again. Certain fish are more prone to be effected by bad water quality than others. As a matter of fact, your water quality may be perfectly fine for the RTMs but not good enough for Bifasciatums and Carpintes. This is why you can allways expect to find hardy fish at the shop like Oscars, Convicts, Red Devils and Pacus. But fish that are not so hardy ie; Altums, Carpinte, Rivulatus, and most Geophagus are found ocassionally.

Tank is probably overcrowded but its just a temp tank. The parasite meds did not kill the bacteria in the filters. The water always has 0 ammonia and nitrites and the nitrates were never over 40ppm more like 20ppm or less. Adding water to a tank and thinking if you bounce it off something there is no need for chemicals is incorrect. Chlorine will dissipate out of water over time but most water has chlorimin as well and that does not dissipate. Lucky for me my water is well water and does not have any of the stuff in it.

The spots seem to not be getting any worse...dare I say some maybe better...real slow going what ever its doing. Fish still eating great and im still doing my daily doses. Bifasciatums lip is 100% better but was well on the way to that before this outbreak so I dont know if its related? I will try to get some updated pics soon.
