I thought salt would hurt the corydora? I have some, and have done another partial water change and checked the ammonia again but it hasn't gone down so it may be due to new fish added, I threw a bit of "Safe Start" in to hopefully boost the bacteria as well...

That was my initial thought, because I think I've been seeing fungus on some of the dead/dying fish, but this looks a little different than what I had been seeing. Unfortunately I have no LFS nearby, and have to drive an hour to get to anywhere that has fish meds.

I hadn't noticed a change in their aggression but they are still eating, I will have to watch and see if they seem to go after anyone, though.

I just noticed it earlier today and also found a second one with a smaller amount of it after posting this, they are swimming slower but aren't seeming hurt. I did see one flashing against a plant as well.

I purchased the med trio recommended on the website for treating new fish and plan on using it asap, but it has been misdirected to another town by the post office. As a temporary emergency solution I am using Tetra Lifeguard but I've lost at least two Corydora to whatever the issue with my tank is. Until this outbreak my parameters were looking good, but as of this morning they sit at Tank is a 36 gallon bowfront Temp: 78 degrees PH 7.4 Ammonia .25 Nitrite 0 Nitrate 20 (I'm new to trying to read these last two tests so I think it was) KH 100-200 (took 7 drops to change color) GH 50-100 (4 drops for color change) I changed out 5 gallons this morning before running out for emergency meds. I had a cory that was also not doing well but I think he has died just since I got back with the meds. Stocked with 7 rasbora, ~10 albino cory (the count is unclear, they don't wanna stay still for me to count heads) and 8 blue wag platy.
