Common questions

What should I check before acting on this advice?

Koi are a species of freshwater fish that are popular in both aquaculture and ornamental ponds. They are a member of the carp family and can grow to be quite large, with some individuals reaching over two feet in length. For more pond-care guidance, read How Long Does It Take A New Pond To Fill? and review MSD Veterinary Manual: Fish nutrition. Start with the specific details in this guide, then check recent changes, the surrounding conditions, and any relevant measurements before taking action.

Does one observation prove the answer?

No. A single color, behavior, symptom, price, or pond reading can have more than one explanation. Compare it with the wider context and look for a repeated pattern before making a major change.

When should I ask for help?

Ask for help when the situation is severe, affects several fish, involves a possible toxin or injury, keeps worsening, or cannot be explained by the available observations and tests. Keep notes and product labels available.
