- Occasional fasting(e.g. one day) in healthy adults can help cleanse; not in fry or sick people without criteria.
- Alternate formats (flakes, grains, frozen-thawed) depending on species.
Signs of excess
- Debris at the bottom, cloudy/green water, high nitrates.
- Obese fish or fish with constant abnormal feces.
