- Supplement with leafy greens (lettuce, spinach), fruits (orange slices), and protein sources like earthworms, shrimp, or silkworms.
-
Tank mates:
- Compatible with other koi and large, peaceful pond fish such as goldfish and orfe.
- Avoid mixing with aggressive or small fish that may be outcompeted or mistaken for food.
-
Behavior and Compatibility:
- Butterfly Koi are graceful, peaceful fish known for their long flowing fins and friendly behavior. They often recognize and interact with their caretakers.
- They are social and should be kept in groups to prevent stress and promote natural schooling behavior.
