A special lid makes dosing easy and accurate.
Why goldfish need their own food
Goldfish are coldwater fish with no true stomach, and their digestion is designed for frequent small meals, including plant food. Food for tropical fish is often too rich for them. Goldfish also eat and excrete a lot, so a highly digestible food helps keep the water in good shape. More on feeding different fish in aquarium fish food: how to feed.

How to feed
Feed 2–3 times a day in small portions that the fish eat within 2–3 minutes. Goldfish always seem hungry, but overfeeding is dangerous for them: it causes digestive and swim bladder problems, and uneaten food fouls the water. Some fishkeepers briefly soak the flakes in tank water before feeding so the fish swallow less air. A fasting day once a week is beneficial. Supplement the diet with plant food, such as blanched lettuce leaves.
Keeping goldfish
Goldfish need a spacious tank — roughly 40–50 litres per fish — a powerful filter and a partial water change every week. They shouldn't be kept in small round bowls, where waste builds up quickly. It's best not to mix them with tropical fish because of different temperature and feeding needs. Where to start is covered in an aquarium for beginners: what to buy, and Rikka AKVA START helps establish the biological balance. For tropical fish, the all-round TetraMin is a good choice.
Who it suits
Goldfish of all varieties — from comets to fantails and orandas — and other coldwater fish. More foods are in the fish food section.
Verdict
