Understandable! It can be hard to tell sometimes But bacterial infections can spread too, and fungal infections tend to happen on a wound or injury, and look distinctively fluffy. If you google image search for fish fungal infections, you'll see the difference.
I hope they show signs of improvement soon!
Id treat the tank, since the one is so severe.
But save some of your filter media separately so you can re-seed it. You may get a mini cycle but its better than fully losing it.
Alternatively you can move the affected fish to a hospital tank and treat that instead
so i took a closer look at the peppered corydora (the one with what i thought was fungus). you guys are right, it's not fungus unless fungus puts a hole in them. she has a longer, more line shaped "hole" near her eye, whereas the other corydora had just the hole. i hope her eye will be okay. i guess it's possible that both scraped themselves and one gave the infection to the other. luckily both are still eating and doing okay for now. i'll continue to update you guys, i bought everything like i said before and i hope they can hang on until everything gets here. i added in some aquarium salt as well. thanks for all your help!
