So I have two bettas, Louie (red) and Otto (blue). I've had them for a little more than a year, but I just now discovered this forum since Louie had an infection and I needed troubleshooting!
Anyway, I was thinking about Otto. Below I have a pic of him, he looks about the same as when I bought him at Petsmart except maybe a little fatter! Is his color ok? When I bought him, I noticed he wasn't completely blue but for some reason I thought it just meant he was one of the older fish (hence kinda why I got him lol), but I just want to make sure he doesn't have fin rot or if there's a way for him to get some color back (unless that's his original color...).
