Hello all. A couple of days ago, I noticed a guppy with small, raised, white growths near the base of her pectoral fins, as well as what looked like dead white skin on the rim of her eyes. I isolated her immediately. The day after, another guppy showed the same symptoms near the eyes.
It could be popeye, but I'm not sure. I started to suspect a bacterial infection, since I read that popeye is a symptom of that.

Last night, I started to notice a very thin white perimeter on the lips of some guppies in the main tank. It is not protruding right now and doesn't affect their eating. Granted, I can't be sure if they were always like this, but I'm starting to worry that it is columnaris.

Ammonia and nitrite are 0. Nitrates around 40ppm. The tank is admittedly overstocked and I am starting 20% daily water changes.
Am I overreacting? I cannot observe any behavioral changes yet. None of the fish have "saddleback" or torn fins either.
I have already prepared some medicated food with Kanaplex and Metroplex, but I'm still uncertain. Should I begin dosing? Or wait for more symptoms before pulling the trigger? What should I look out for?
Any insight or advice would be highly appreciated!![Folded hands :pray: 🙏](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f64f.png)
