Blues is acting fine and normal. Today is fasting day for him so I am reading next to him to keep him company since he might be pretty hungry today. I find a lighter color spot on him when he flares. I wonder if it is any early sign of betta disease. In addition, I also wondering if his not very straight tail/dark freckles/little pouches is normal? He always has it since I got him about a month ago. This is my first betta so I don't really know what fin rot looks like. Attached pictures are 2 shots of his tails, one flaring pic with light spot and one not flaring pic which can't see the spot. I know I might be a little paranoid because my inexperience, Thank you!
