Why this matters
In our evaluation, we found that sinking pellets generally produced less waste than floating options, likely because fish could eat more deliberately without gulping air.

Before You Buy
Key Buying Factors
01
Ingredient Quality
Look for whole fish or fish meal as first ingredient; avoid excessive fillers like wheat or corn.
02
Pellet Size & Shape
Large fish need appropriately sized pellets to prevent choking; shape affects sinking behavior and ease of eating.
03
Sinking vs Floating
Sinking foods mimic natural feeding for bottom-dwellers; floating foods allow observation and target feeding.
04
Nutritional Balance
High protein (40%+) for carnivores, moderate for omnivores; vitamins and minerals support color and health.
05
Water Quality Impact
Low-waste formulas reduce ammonia spikes; we observed cloudiness and residue in our tests.
06
Price Per Gram
Larger containers offer better value, but verify freshness; open bags should be used within months.
Living With It
Care, Cost and Maintenance
Feed Amount
Offer only what fish can consume in 2-3 minutes; overfeeding fouls water and causes health issues.
Storage
Keep food in a cool, dry place; use within 3 months of opening to maintain freshness and vitamin content.
Supplementation
Even high-quality pellets can be complemented with occasional frozen or live foods for variety.
Pro tip
To encourage feeding in shy fish, we recommend pre-soaking sinking pellets for 30 seconds to reduce initial sink rate and give them time to intercept.
Frequently asked questions
Can I feed my koi floating pellets year-round?
In winter when water is below 50°F, switch to a wheat-germ based food that is easier to digest. Floating pellets are fine in warmer months.
How do I know if a pellet is too large for my fish?
If your fish cannot comfortably fit the pellet in its mouth, it's too large. Our picks range from 3mm to 9mm; choose based on your fish's size.
What's the difference between floating and sinking food for cichlids?
Floating foods encourage surface feeding, which can be less natural for bottom-orienting cichlids. Sinking foods reduce aggression at the surface.
How often should I feed large fish?
We recommend 1-2 times daily for adults, but adjust based on activity. Overfeeding is a common mistake; we feed what fish eat in 2 minutes.
Can I mix different foods for variety?
Yes, rotating between a staple pellet and occasional treats like frozen shrimp can improve nutrition and interest. Our top picks are balanced enough for daily use.
