Originally bred from wild carp in China over a thousand years ago, goldfish have become a staple in aquariums and ponds around Australia. There are over 200 recognised varieties of goldfish, each with its own unique characteristics in terms of color, body shape, fin configuration, and scale type. Goldfish are also known for their social behaviour. While they can be kept alone, they often thrive when kept in groups. With proper care, goldfish can live for decades, with some documented cases of goldfish living over 20 years. This long lifespan, combined with their peaceful nature, makes them a long-term companion for those who choose to keep them.
