Koi Betta Care Guide
Betta splendens var. Koi · Freshwater Fish
What Koi Betta look like
Koi Bettas are domestic Betta splendens selected for irregular marble color patches. The pattern may shift over time as the fish matures.
Behavior & temperament
Care is standard domestic betta care: warm stable water, surface access, gentle filtration, and careful tank mate selection. Males are territorial.
Diet & feeding
Koi Bettas need protein-rich betta pellets and small frozen or live foods such as daphnia, brine shrimp, mosquito larvae, and bloodworms.
Behind the name
Koi describes the ornamental patchwork color pattern, not a relationship to koi carp.
Plan your tank
Check the numbers before you buy: tank volume, a stocking plan, cycle progress, water changes, and your ongoing care routine.
