Fancy Goldfish are a prized fancy variety distinguished by their rounded bodies, prominent dorsal humps, and flowing fins. Growing to 4-6 inches, they display vibrant colors including orange, red, white, and calico patterns. These peaceful, moderately active fish thrive in cooler water (65-75°F) and require a minimum 20-gallon tank with quality filtration and weekly water changes. They prefer slightly alkaline conditions and benefit from soft substrates, plants, and hiding spots. Feed a balanced diet of high-quality goldfish pellets, blanched vegetables, and occasional live or frozen foods. Ideal for community tanks with compatible species.
