The Black Butterfly Goldfish is a darker, velvety appearing goldfish that gets along great with other Goldfish. This fish is a variant of the Black Moor Goldfish: it has eyes that telescope, but do not protrude as much as many others of its genus and this goldfish gets its common name from the shape of its tail. Hardy and long-lived, they can survive cooler temperatures. Extended periods below 60 F or above 80 F may not be tolerated well. Because they need some vegetable matter, Black Butterfly Goldfish may cause damage to finer-leaved plants, but typically do no damage to thicker, hardy bog plants. While flake food will suffice for Black Butterfly Goldfish, many aquatic professionals recommend a good-quality pellet food.
