Black Moor Goldfish are elegant fancy goldfish distinguished by their velvety black coloration and prominent, protruding eyes. These peaceful, moderately active swimmers typically reach 4-6 inches and thrive in cooler water between 65-75°F. They require a minimum 20-gallon tank with good filtration, soft substrate, and regular water changes. Black Moors are omnivorous and do best on high-quality sinking pellets supplemented with blanched vegetables and occasional live or frozen foods. Their color can fluctuate based on water quality, and they make excellent community tank residents when paired with compatible tankmates.
