My Rainbowfish has this on both of his sides (right side much worse) it looks like a red ulcer/lesion and skin looks like it’s showing when viewed from the side but looks like the scale is raised and puffy when views from the tail, and has some tapered fins, any ideas what this is? Possibly fish TB (mycobacterium)!!!??He’s still eating and swimming but he’s starting to rub his sides against the tank (so are my loaches) so I started a dose of aquarium salt and API melafix tank is planted 75 gal and has plecos, archers, loaches, and rainbows, temp is 76, ammonia: 0, nitrite: 0, nitrate: 0.5, and pH: 7.5, i have a eheim pro4+ and tidal 55 and power head, I’m doing water changes (75%) every 2 weeks, and lights are on for about 12 hours a day. Power head was recently added a power head but nothing else is infected like he is. Any help is appreciated thanks!

I guess your water quality is pretty good, I have heard that the Tidal is the best HOB filter on the market. I think that it's possible that your fish has an injury, but the fins make me believe that it may be a bacterial / fungal issue, if it is an injury it will heal over time, but if you have a tank available to use as a hospital I I'd treat the fish with nitrofurazone, and do weekly water changes instead of every 2 weeks, good luck.
 
More info please....number of each fit? Sex? Full tank shot? Maintenance routine?
