Red gills?
Hello, everyone!
I have some black neon tetras (there are 6 total) that have these bright red gills that are also kinda poking out a bit? (see pictures below) I first noticed it on the 29th and there were two showing these symptoms. The next day I found a third one with the same symptom but only on one side. They eat, swim around, and they aren't gasping for air. Today, I noticed another tetra-one that doesn't have these red gills-has a bit of white cotton-like stuff on it's mouth.
I'm not experienced with fish illnesses (I'm relatively new to the hobby) so I'm not sure what is going on or what to do about it, if anything. I've attached some pictures, and for help, here's a brief rundown of my tank setup...
I have a relatively new tank - it's been up for 2 months. 20 gallons, planted, fluorite substrate, and running CO2. It was first set up in May, then I did a fishless water cycle with daily testing. Once ammonia, nitrites, and nitrates all reached 0 I gradually added fish from June 17 to June 24. The black neon tetras in question were added June 23rd, so they've been in there about a week. I add flourish (1.5mL) and excel (2mL) daily. I didn't quarantine any of the fish before adding them and I dumped the water that was in their bags into the tank with them (oops?). They were all acclimated by floating on top of the tank for about 45 minutes and gradually adding the tank water to the bags.
Stocking:

Any advice or suggestions on this matter is appreciated!
