My Betta seems to have recently developed little black dots on his fins on both sides about a week after moving him from a small bowl to a little Top Fin 2 gallon (7.6 L) aquarium with a heater.
He eats pellet style Betta food and lives with a little nerite snail named Reggie. NowIt is possible that these dots may have just gone unnoticed until now, but I feel like they are new. Any ideas as to whether this is disease related?
