How scoring changes by life stage
We score foods against macro ranges for your fish's diet group. Life stage adjusts those ranges:
- Fry: higher protein and energy needs, lower tolerance for high fibre
- Juvenile: higher protein and slightly higher fat than adults
- Adult: balanced staple ranges for everyday feeding
- Conditioning: higher-fat ranges for breeding prep and recovery
