Goldfish (Carassius auratus)

GOLDFISH (Carassius auratus) ARE AMONG THE MOST POPULAR and common fish to be kept in aquariums and ponds. They are popular among beginners, particularly because of their cost, abundance, and, we could say, fortitude; furthermore, goldfish are freshwater fish that can survive in temperatures that are comfortable for humans, and there's no need to use heaters or coolers.

Due to many hundreds of years of domesticated selection and breeding, goldfish are now available in a wide variety of sub-species, including those with wildly varied colouration, eye and fin configuration, and body shapes that deviate from common goldfish (should 'common' goldfish be used as a benchmark against the others). In fact, there are around 300 different variations of goldfish officially noted in China, where goldfish originated from.

In this guide, we want to show you some of the most common goldfish for aquariums in the UK, their feeding habits, the best methods for looking after them, as well as other tidbits of information such as aggression and partnerships. Read on.
