Pond comets, also known as comet goldfish, are a variety of single-tailed goldfish commonly found in outdoor ponds and aquariums. They are known for their sleek bodies, long flowing tails, and vibrant colors, which can range from orange, red, yellow, white, and even calico patterns.

These fish are hardy, active, and playful, making them a popular choice for pond enthusiasts. They can grow up to 12-14 inches in length and live for 10-20 years if provided with proper care. Comet goldfish thrive in spacious environments with plenty of room to swim and are often kept alongside koi in garden ponds.
