How to Care for a Goldfish Properly

The goldfish is undoubtedly one of the most popular fish species as well as one of the most long-living, they can live six to eight years if properly cared for. Their many colours and physical variety have made them a necessary member of all tanks and aquariums, due to their beautiful appearance. So if you are thinking of getting one of these as a pet, will tell you everything you need to know on how to choose and care for a Goldfish properly.

Steps to follow:

When choosing a goldfish, it's important that you consult with a specialist at the pet store because their diversity in size and appearance can sometimes make them difficult to identify. They're so varied that you could have an aquarium of only these fish and it would still look exciting.


The Goldfish is a slow type of fish, so it is important for it to live with other species of goldfish or with a breed that moves at the same speed, such as the rainbow shark. Otherwise if it lives with fast fish, the way they eat and move also needs to be fast, so it could make the goldfish stressed and malnourished.


Like for any pet, this fish requires specially designed food for it and its nutritional needs. Portion sizes can be tricky, but experts say the amount of food should be equal to what the fish can eat in two minutes.


These fish are very greedy, so it is important to pay attention to the portions and respect the quantity recommendations because they'll never leave food in the tank but could be eating too much.


The goldfish has a long lifespan, living between 6 and 8 years and growing to 10 to 15 cm. Every adult fish requires at least 38 litres of water, meaning that it needs plenty of space, so if you want to have several of them you will need a large aquarium.


Don't forget that company is important to the fish, so give your goldfish a partner to keep it entertained.
