Problem: I just noticed yesterday that my Panda Cory possibly has fin rot, but I noticed there's white spots just on the fin as well. It doesn't look like ick to me, it's more fuzzy and splochy as you can see in the photo. I am wondering if there's some fungal infection as well? Backstory: I have a 10 gallon tank with heater (turned off because it's summer and water stays at 80 F) and AquaClear 30 filter on low settings. I have 0 Ammonia, about 5 ppm Nitrites, about 2 ppm Nitrates. It's still in a cycle for about the last month and a half. I have one other Panda Cory that has no signs of fin rot or the white spots. I also have a Betta as well without fin rot that I can tell, but has some fin damage from a Blood Fin tetra that I had for about 2 weeks before returning to the pet store. I used to have one more Panda Cory for a total of 3 but it died about a week or two ago. That cory didn't have fin rot either. I believe it died because of high Nitrites, which I thought I was monitoring closely, but I guess not closely enough. I do a water change about 50% every week with a gravel vac. Things I have tried: Right after I saw the issue yesterday, I did a 25% water change with a gravel vac and added Prime and a double dose of StressGuard. So any ideas? Is it just fin rot or is there a fungal infection I have to worry about as well?
