Goldfish are one of the most popular pet fish species and originate from Asia and Eastern Europe. Goldfish need to be kept in a tank according to their body size, and with the right amount of space can grow to be around 30cm long! Similar to tropical fish they need specific water parameters, LED lighting and tank filters. Goldfish are quite social and do well living in pairs or small groups. With the correct environment and care goldfish can live between 10 to 15 years, with some species reaching 30 years old!
