Behavior and Aquascaping:
Ryukin Goldfish are peaceful and active swimmers that thrive in open spaces. Add soft plants or smooth decorations to enhance the tank’s aesthetics while minimizing the risk of injury to their fins. Efficient filtration is necessary due to their waste production.
Additional Tips:
Regular water changes are crucial to maintaining water quality. Their compact body shape can make them more prone to swim bladder issues, so avoid overfeeding and provide a varied diet to support digestive health.
