SKU: FM-OP-01
- Fauna Marin Ocean Plankton is a 100% natural Calanus plankton food caught fresh from the Norwegian North Atlantic.
- The 250ml size suits established reef systems with multiple corals and fish feeding daily from the same bottle.
- At 72.4% crude protein on dry weight, it delivers exceptional nutrition in a highly concentrated conserved format.
- At 250ml, it is the larger supply option for reefs using Ocean Plankton daily across corals and multiple fish.

Norwegian North Atlantic Calanus Plankton for Established Reef Systems
Fauna Marin Ocean Plankton (250ml) is a 100% natural Calanus finmarchicus plankton food sourced fresh from the Norwegian North Atlantic Ocean and immediately conserved. It is not a frozen product and requires no defrosting — it doses directly from the bottle the moment you open the cap. The 0.5–1.0mm Calanus particle is sized to serve both LPS and NPS corals and marine fish in a single daily dose, making it one of the few reef foods that works across the full biological range of an established mixed reef without requiring separate coral and fish feeding schedules.
The 250ml bottle is the regular-supply size for reefs running Ocean Plankton as a daily staple. At this volume, the supply sustains consistent daily feeding through an extended period without the risk of running out mid-month that comes with the 100ml. The formula remains unchanged: 100% Calanus finmarchicus, water, EC-approved antioxidants, and salt, delivering 72.4% crude protein on dry weight and a minimum of 1200 mg/kg natural carotenoids. Those carotenoids come from the whole Calanus organism, not from synthetic pigment additives, which is meaningful for hobbyists prioritizing natural sources of color enhancement in their feeding program.
Key Features:
- 100% natural Calanus finmarchicus ocean plankton with no artificial ingredients or additives
- Freshly caught from the Norwegian North Atlantic Ocean and immediately conserved
- Conserved format requires no defrosting; ready to dose directly from the refrigerator
- 0.5–1.0mm particle size serves LPS corals, NPS corals, and marine fish in a single dose
- 72.4% crude protein on dry weight for exceptional nutritional density
- Minimum 1200 mg/kg natural carotenoids from the whole organism for color support in corals and fish
- Contains natural enzymes and fatty acids integral to the Calanus plankton
- Enhances coloration, growth, and resistance in both corals and fish
- Highly concentrated; small daily doses supply the full system
- Accepted readily by recently imported and selective marine fish
- 250ml size supports consistent daily feeding in established multi-coral reef systems
Ideal For:
- Established reef systems with multiple LPS and NPS corals and active fish stocking where Ocean Plankton is used as a daily food and the 100ml would be depleted too quickly
- Reef hobbyists who have confirmed their corals and fish respond well to Ocean Plankton and are ready to transition to the larger supply size
- Reef stores and aquarium retail locations stocking Ocean Plankton in their coral food section who need the standard full-size bottle for display and sell-through
Pro Tips:
- Establish a consistent daily feeding time and stick to it. LPS corals extend feeding tentacles more reliably when food arrives on a predictable schedule. Reefs fed Ocean Plankton at the same time each day typically show noticeably better polyp extension over several weeks than systems where feeding time varies.
- Use a dosing pipette or target feeder to place food directly at each coral head. At 250ml you have ample supply to be generous with targeting, but precision still beats broadcasting. Directing the dose within a few centimeters of a coral's mouth significantly increases capture rate and reduces the amount that cycles into the skimmer unused.
- Do not skip refrigeration between doses. Ocean Plankton is conserved, not frozen, which means it remains fresh at refrigerator temperature but will degrade faster at room temperature over repeated exposures. A tight cap and immediate return to the fridge after each feeding session extends the opened bottle's usable life substantially.

While most of our equipment carries a one-year manufacturer's warranty, consumable products like fish and coral foods are not covered under traditional warranty terms due to their perishable nature and varied storage conditions. However, we fully stand behind the quality of every product we sell. If you experience any issues with your food purchase shortly after receiving it, such as concerns about freshness, packaging integrity, or product quality, please contact us at [email protected]. We're committed to making it right and will work with you to resolve any problems quickly and fairly.
Instructions:
- Shake the bottle gently before each use.
- Reduce or temporarily pause circulation pumps and powerheads to minimize current during feeding.
- Dose directly near coral polyps or into areas of the tank where fish and corals are concentrated. A pipette or target-feeding tool provides the most efficient placement.
- Allow two to three minutes for corals to extend polyps and begin capturing particles before restoring flow.
- Feed daily in small amounts. Start conservatively and increase based on the feeding response of your corals and fish.
- Replace the cap tightly after each use and return the bottle to the refrigerator immediately. Do not leave at room temperature for extended periods after opening.
Note: No defrosting is required before use. This product is conserved, not frozen, and feeds directly from the refrigerator.
