Hi guys, one of my betta's eyes is a little swollen, slowly getting bigger. I first noticed it about a week ago and thought maybe he scratched it on something but it hasn't gotten better. It's a 6 gallon tank pH is around 6.8, temp is between 77 and 79 and ammonia & nitrites are 0. Any idea what's causing this? I did recently add an adf to the tank, could that be causing it?
