Okay, so she is in the hospital tank. It doesn't have gravel, I just thought it would be easier for daily changes. I have one big plant and one little plant, but they are both fake. I think I have some stress coat, but I'm not sure. I don't have aquarium salt, but I will get some. She is in a 1.6 gallon bowl. How long do you guys think it will take to heal?
Here's a pic (I took out the plants for the photo, they are back in):
How much of her water should I change every day? Thanks so much!
Edit: forgot to add there are no signs of fin rot.
