Im sorry for the loss of your fish. It could be, but without an exam it is difficult to say definitively. Some fungal or bacterial infections are contagious. Monitor the other fish for similar symptoms. Maintain pristine water quality and consider an "all-in-one" treatment if necessary. You can find these treatments in the aquarium section of the local Petco. Follow label directions carefully and remove the carbon filter insert during treatment if indicated.
