I just got a blood red betta from my lfs. This is my first and I decided to cycle the tank with the fish in it. My problem is it appears there is some kind of white spot on the outside of the fish's eye, almost like speck of something on it. I have a 5 gallon hex with a bio wheel by the way. I am also looking to add some more fish but don't really want to go with white clouds. What else should get to compliment my betta?
