Ryukin Goldfish

The Ryukin Goldfish was developed in Japan and looks similar to the Fantail Goldfish, except for the hump back that begins right behind the head. A high hump is considered very desirable. The Ryukin Goldfish is one of the more broadly known and popular goldfish types in the United States. The body of the Ryukin Goldfish is extraordinarily deep; almost as deep as the body is long, and the high dorsal fin make the fish look even higher. The Ryukin Goldfish was originally red, but can today be found in a large variety of colours, including pure white, blue, calico, green/greenish, chocolate and red and white combinations. A calico coloured Ryukin Goldfish usually have much smaller hump. All Ryukin Goldfish have two anal fins, two ventral fins and two pectoral fins and they should be evenly paired. The caudal fin can be longfinned, ribbon, short tailed or butterfly.

You need to follow a few rules to keep your Ryukin Goldfish happy, such as giving it enough space, but apart from that the Ryukin Goldfish is not very tricky to keep. It is an active fish and can be housed with many other types of goldfish. Avoid keeping it with weaker variants, such as Telescope Goldfish and Bubble Eye Goldfish, since they will probably be bullied by the stronger Ryukin Goldfish. Lionhead Goldfish, Oranda Goldfish and Ranchu Goldfish are more suitable companions since they are sturdier.

You should provide your Ryukin Goldfish with at least 20 gallons of water. A small juvenile Ryukin Goldfish can do well in 10-15 gallons, but as for all goldfish – the more the better! A Ryukin Goldfish can grow up to 10 inches long if provided with good care and enough space. A pond is ideal for the Ryukin Goldfish since it will have much more room in a pond. The Ryukin Goldfish produces a lot of ammonia and other waste products, and will therefore never thrive in small or crowded aquarium. You should always make sure that the nitrates stay below 20 ppm, since higher nitrates will harm the swim bladder of your Ryukin Goldfish. Since the Ryukin Goldfish is so deep bodied, it will always be prone to swim bladder problems. When you choose your Ryukin Goldfish you should avoid those individuals that are head standing or floating in the aquarium, since this is a sign of severe swim bladder problems. Choose a Ryukin Goldfish that is evidently a strong swimmer and capable of forcefully pushing the water aside as it makes its way through the aquarium.

A Ryukin Goldfish will eat almost anything you feed it, and quite a few other things as well such as aquarium plants. Do not feed your Ryukin Goldfish floating flakes or floating pellets. The sinking type of flake food and pellets are okay, as long as you soak it properly beforehand. Your Ryukin Goldfish will do well on a varied diet, as long as the diet includes vegetable matter. You can feed your Ryukin Goldfish frozen foods such as cocktail shrimp, bloodworms, daphnia, and krill brine shrimp. It will also do well on soaked spirulina flakes, lettuce, algae and peas.
