I need help, I don't know what to do or if he is healthy or not. My newly bought betta is swimming around normally and eats his food as soon as it gets soft enough to fall from the surface of his water. His water from his container was not put into his bowl and he even started a bubble nest. However there is one strange spot on him that I can't find anything about. It is white, on one side of his body and has a black spot on his upper back. His scales are not raised or anything and I don't know if it's rot, ich, or just some weird coloration. Please, I need to know that he is okay.
