Ryugan (Dragon Eye Oranda)
The Ryugan, also known as the Dragon Eye Oranda, is a Chinese goldfish variety that combines the plump, rounded body of the Oranda with the bulging, telescope-like eyes of the Demekin. Its name, meaning "dragon eye," comes from the way its well-developed head wen and large protruding eyes evoke the face of a dragon. With its slow, graceful swimming style, it makes a striking centerpiece in any tank. That said, its delicate eyes are prone to injury, so this variety is generally best suited to keepers with some prior experience.

7 things to know before welcoming a Ryugan (Dragon Eye Oranda)
1Delicate Bulging Eyes
The large protruding eyes are easily bumped or scratched. Keep the tank layout simple, avoiding sharp decorations or coarse substrate that could injure them.
2Choose Tankmates Carefully
Because its body shape makes fast swimming difficult, quick or aggressive tankmates can injure its eyes and body. Pairing it with other slow-moving goldfish of similar temperament works best.
3Frequent Water Quality Care
This delicate body type is sensitive to poor water quality, so regular water changes and reliable filtration are essential. A buildup of ammonia or nitrite can lead to eye problems and general ill health.
4The Head Wen Develops Slowly
The head wen develops gradually as the fish matures, often taking years to fully form. Growth varies widely between individuals, making it a variety you can enjoy watching change over time.
5Watch for Swim Bladder Issues
Round-bodied goldfish varieties are prone to swim bladder disorder, which can cause floating or sinking issues. Avoid overfeeding, and soaking dry food before feeding can help reduce the risk.
6Feed With Its Eyesight in Mind
With its eyes bulging outward, this variety can be slower to spot or react to food than other goldfish. Watch feeding time closely to make sure it isn't being outcompeted by tankmates.
7Prepare the Tank Beforehand
Before bringing one home, set up a tank with adequate size, filtration, and a safe, low-hazard layout in advance. Take care to acclimate it slowly to its new environment.
