Before You Buy
Key Buying Factors
01
Ingredient Quality
We prioritize whole proteins like fish meal and salmon, avoiding fillers like corn or soy. Look for certified organic sources.
02
Nutritional Balance
Fish need a balanced mix of protein, fats, vitamins, and minerals. We check guaranteed analysis and feeding recommendations.
03
Floating vs. Sinking
Floating pellets are ideal for surface feeders like koi and goldfish, allowing you to monitor consumption and reduce waste.
04
Digestibility
Highly digestible ingredients mean less waste and better water quality. We look for natural probiotics and prebiotics.
05
Color Enhancement
Natural color enhancers like spirulina and astaxanthin bring out vibrant hues without artificial additives.
06
Water Stability
Pellets should hold shape for several minutes without disintegrating, preventing cloudiness and ammonia spikes.
Living With It
Care, Cost and Maintenance
Feed According to Season
In warm months, feed once or twice daily as much as fish can consume in 5 minutes. In cold months, reduce or stop when water temperature drops below 50°F.
Store Properly
Keep fish food in a cool, dry place away from direct sunlight. Seal the bag or container tightly to prevent moisture and spoilage.
Monitor Water Quality
Overfeeding can cloud water and increase ammonia. Use a test kit regularly and adjust feeding amounts if needed.
Pro tip
Our team recommends rotating between two high-quality foods to provide a varied diet and prevent nutritional gaps. Always read the guaranteed analysis to match your fish's protein needs.
