Ocean Nutrition frozen copepods
Whole frozen copepods for fussy marine feeders. Ocean Nutrition Frozen Copepods is a 100 g pack of whole marine copepods, sized at roughly 500 to 800 microns — small enough for mandarin dragonets, seahorses and other picky eaters that turn their noses up at larger frozen foods. It suits reef and marine fish-only systems where natural HUFA and astaxanthin content matter for colour and condition.
Key features
- Whole copepods, not a blend — a single-ingredient food, so there's nothing to pick around.
- Small particle size (500–800 micron) — sized for small mouths: mandarins, pygmy angels, seahorses and juvenile fish.
- High in HUFA and astaxanthin — supports natural colour and condition rather than just filling a gut.
- Good buoyancy in seawater — stays in the water column longer, giving slow, deliberate feeders more of a chance to find it.
- 35-cube blister pack — easy to portion one cube at a time without breaking into the rest of the pack.

Ingredients
As declared on pack: "Copepods (crustaceans)." Ocean Nutrition does not publish a guaranteed analysis (protein, fat, fibre, moisture, ash) for this product — check the current pack for any figures printed since this page was checked.
Suitable for, and not suitable for
Suited to mandarin dragonets, wrasses, damsels, anthias, pygmy angels, basslets, groupers, boxfish and pufferfish, seahorses, razorfish, surgeonfish and triggerfish, plus reef invertebrates and shrimp that take frozen foods. Not a food for herbivorous grazers such as tangs looking for algae-based nutrition, and not a substitute for a varied diet on its own — rotate it with other frozen and dry foods.
Feeding and thawing
Thaw a cube in a small amount of tank or system water rather than dropping it in frozen — this stops a slug of cold water hitting the tank and lets you judge portion size. Never refreeze thawed food. Ocean Nutrition doesn't publish a specific feeding frequency for this product; feed only as much as fish and invertebrates will clear in a few minutes, and for slow or shy feeders such as mandarins and seahorses, target-feed with a pipette or turkey baster so the food doesn't get lost to faster tankmates or the filter.
Warranty, delivery and storage
Keep frozen until use and never refreeze once thawed. This is a frozen product — check with the store before ordering if you need it kept cold in transit, as our published delivery terms don't currently spell out cold-chain handling for frozen foods. As with all consumables, your rights under the Australian Consumer Law apply in addition to anything stated here.
Common questions
Can I feed the cube frozen, straight into the tank?
Ocean Nutrition doesn't give cube-drop instructions for this product the way it does for some of its other frozen foods, so the safer approach is to thaw a cube in a small cup of tank water first, then add it — that avoids a sudden temperature drop and lets you control the portion.
Will this cloud my water?
Thawing before feeding and only offering what will be eaten within a few minutes is the main way to avoid this — uneaten copepods breaking down in the water column is what causes cloudiness, not the food itself.
Is this a complete diet on its own?
No single frozen food is. Rotate copepods with other frozen, freeze-dried or dry foods so fish get a broader range of nutrients.
What size fish can eat this?
The 500–800 micron particle size is aimed at small-mouthed feeders — mandarins, pygmy angels, juvenile fish and seahorses — rather than larger predatory species, which are better served by a coarser frozen food such as krill or mysis.
Goes well with
Works well rotated with other Ocean Nutrition frozen foods to add variety to a marine or reef diet, particularly for tanks holding a mix of small and larger feeders.
