I am re-entering the hobby after a 7 year hiatus. I am new to planted tanks. I have a 10 gallon planted tank with 3 amano shrimp, 2 nerite snails, 2 blue Neocaridina shrimp, and 7-> 6 neon tetras. The planted tank has been set up since May 3rd. Two of my tetras had a white small growth on their lips. What is it and how do I treat it?
My fish tank parameters:
10 gallon tank below with some modifications to the sump style filter to contain bio rings and course filter pads. Also running an air stone

3 of the tetras I had since 5/24 and the other 4 since 10/4. I put the old fish through 2 rounds of meds (the trio recommended by aquarium coop) when I got them. I put the new fish through 2 rounds of meds in quarantine (~6 weeks of quarantine) when I got them. I added the new fish to my old tank 11/17. Then one of the old tetras got the growth on his lip. A day after I noticed the growth it started breathing faster. 1 day later I found him dead. One of the new tetras has had a similar looking lip since I got it. However it is eating well and behaving normally so I did not think it was a problem. Looks like I was very wrong. The lip abnormality on the new fish did not respond to the two rounds of med trio. What do I do now? Salt? Repeat med trio? Other Meds? If I use salt do I need to remove all my plants to prevent them from dying? I am so afraid all my fish will die.
Enclosed are pics of the old tetra with the lip growth 1 day prior to death, and a picture after death. I could not get pics of the new fish with the lip growth because he is a fast little bugger. Also pictures of my aquarium for context.
