Buying Guide: Key Purchase Considerations
- Fish size and growth stage: Choose a formula with appropriate protein levels and pellet size to match koi age, size, and feeding capacity.

- Temperature suitability: Many growth-focused diets are best used when water temps are 50°F and above; adjust feeding frequency in cooler months.
