I'm back with another concern: fin rot. There's a very thin black border around Python's fins and I know that can be a sign of fin rot. I do daily water changes and suck up any poop when I see it. I'm cycling a 2.5 Gallon (well trying to, going to the pet store on Thursday to get an API test kit, Stability, and Prime) I know the first thing that's gonna be asked is "can you get a picture?" So I tried. My phone wouldn't focus and if it did, Python kept moving. So I tried using an actual camera on Underwater Mode, no luck. The red light scared Python, there was too much reflection from the sides of the tank and again, Python kept moving. But I was never actually able to see the black on the screen, which makes me believe that if it doesn't show up in a picture it's nothing to worry about? Maybe it's a coloring I've never looked close enough to see? Or maybe her colors are changing? (not sure of her age). Should I add aquarium salt to my shopping list? And at this point is a fish-in cycle my best bet? Does anyone have any pictures of fin rot they could show me? I'm probably just being paranoid but better safe than sorry.
