Koi Behavior tools: what they help with
These tools help you read your koi: temperament quizzes, compatibility checkers for multi-pet homes and guides to what common behaviors usually mean. Most behavior problems start as a mismatch between what a koi needs and what it is getting. Spotting that early is far easier than fixing a habit later.
What to know about behavior and temperament for koi
Koi typically live 25 to 40 years. Koi are pond fish, not aquarium fish. They need a minimum of roughly 3800 liters, at least 1.2m depth for overwintering, and heavy biological filtration to cope with their waste output.
