One of my neon tetra appears to have gill damage - came with it from the pet store. I believe this to be true because unlike the other tetra, his gill is red around the bottom part. No visible bleeding. I've had him for several weeks and despite his gill having some damage, he behaves normally as far as I can tell.
Is there something that I can do to heal this or is this a permanent damage? The fish in question lives in a 55 gallon tank with 3 other neon tetra, a male and female swordtail, a black molly, and 4 clown loaches.
Bonus question: all of my neon tetra open and close their mouths when they swim repeatedly. I've only just recetly noticed this behavior. One of the tetra (not the damaged gill one) does this more exagerattedly than the others. Is this an alert that there is another problem going on with my tetra or is this normal neon tetra behavior? I have read about neon tetra disease and do not believe they have that at all.
