okay so My Betta, Sonic hasn't been eating. All last week the most he had was about 2 pellets. He will get excited when I feed him like usual, but then chews it some.. and spits it out. I just cleaned his tank yesterday and nothing changed except I added new rocks that I washed thoroughly. He still isn't taking any pellets of food. He seems quite happy, still swimming around a lot, but his fins aren't as open as usual. They aren't closed or completely open. Also I've noticed his color has faded and he looks pale. He got more color back when i cleaned his tank. But still pale, kinda white behind his gills.. but pale. I'm not sure what this could be.. or affecting his eating.. ?? ? I don't think its a fungus, nothing is hanging off of him. Please help, and give me your opinion.. Thanks :]
