Koi can be kept with goldfish, topmouth gudgeon, bitterling, white cloud mountain minnow, and medaka. When choosing tankmates, consider size and habits, and pick similar-sized, similar-tempered fish.
Koi are gentle; avoid keeping them with overly aggressive fish so they aren’t bullied. Also, control stocking density to prevent cramped space that affects koi growth.
