Buying Guide

Match food form to species

Use flakes for most tropical community fish, floating sticks for surface-feeding species, and soft sticks or sinking pellets for larger koi and bottom-feeders

Check nutrient balance

Look for foods that list protein, fat, and fiber ratios and include vitamins like vitamin C to support growth and immune health

Choose color-enhancing formulas when needed

Color-boosting blends with natural pigments can help intensify hues for tropical fish and koi without replacing a balanced diet

Consider serving size and packaging

Larger containers suit frequent feeders or big ponds, while smaller packages are better for occasional or specialized diets to preserve freshness

Match feed type to feeding behavior

Floating feeds let you monitor appetite and reduce waste for surface eaters; soft sticks are easier for slow-eating koi to consume
