The fish, up close
The Ryunkin is a fancy goldfish variety known for its vibrant colours and distinctive features. They have a rounded body shape with a double tail fin that resembles a butterfly. Ryunkins can come in various colour combinations, including red, white, orange, and calico patterns. Their metallic scales shimmer in the light, adding to their ornamental appeal. These fish are prized for their beauty and are popular choices for aquarium enthusiasts looking to add an eye-catching element to their tank.
Care guide
Use these notes to shape a setup around the fish, then speak with our team about the tank you have in mind.
Plan your setupBehaviour
Ryunkins are generally peaceful fish that do well in community tanks with other goldfish varieties. They are active swimmers and enjoy exploring their environment. These fish are social and can exhibit playful behaviours when kept in groups. However, they may sometimes compete for food, so it's important to ensure all fish receive an adequate amount during feeding.
Tank planning
Maintaining good water quality is essential for Ryunkins as they are sensitive to poor water conditions. Regular water changes, filtration, and monitoring of ammonia and nitrate levels are crucial for their health. Provide plenty of swimming space and hiding spots in the tank to accommodate their active nature. Avoid sharp decorations that can potentially harm their delicate fins.
