Fauna Marin Ocean Plankton (Calanus) Food, 100 ml

Norwegian North Atlantic Calanus Plankton for LPS Corals and Marine Fish

Fauna Marin Ocean Plankton (100ml) is a 100% natural Calanus finmarchicus plankton food sourced fresh from the Norwegian North Atlantic Ocean and immediately conserved to lock in nutritional quality. It is not a frozen product and requires no defrosting — it pours and doses directly from the bottle at whatever temperature your refrigerator stores it, which means it is ready to feed the moment you open the cap. The 0.5–1.0mm particle size is small enough for LPS and NPS coral polyps to capture and large enough to register as zooplankton-scale prey for marine fish, making it a single food that serves the full biological range of a mixed reef system.

The formula is as close to ocean-origin as a prepared reef food gets: Calanus plankton, water, EC-approved antioxidants, and salt. That simplicity produces a nutritional profile of 72.4% crude protein on dry weight — a concentration that supports coral growth, resilience, and coloration while simultaneously providing a natural, highly accepted food source for marine fish. The Calanus finmarchicus species is naturally rich in carotenoids (minimum 1200 mg/kg), which contribute to the color enhancement effects documented by Fauna Marin. The 100ml bottle is the introductory or smaller-reef size, well suited for tanks that go through this food slowly or hobbyists building a multi-food feeding rotation.

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; feeds directly from the bottle
• 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 supports exceptional nutrition for reef inhabitants
• Minimum 1200 mg/kg natural carotenoids support color enhancement in corals and fish
• Contains natural enzymes and fatty acids from the whole Calanus organism
• Enhances coloration, growth, and resistance in corals and fish
• Highly concentrated formula; small daily doses serve the full tank
• Easy handling and dosing directly from the bottle
• Accepted by recently imported and finicky marine fish with less loss than many prepared foods
• 100ml size is appropriate for smaller reefs or multi-food feeding rotations

Ideal For:

• Smaller reef tanks with a few LPS or NPS corals where the 250ml would sit in the fridge too long before the opened bottle is used up
• Reef hobbyists new to conserved coral and fish foods who want to trial Ocean Plankton before committing to a larger supply
• Established reef keepers who use Ocean Plankton as one component in a multi-food rotation and prefer to restock one bottle at a time rather than hold a large open supply

Pro Tips:

• Reduce flow before dosing and bring it back up after two to three minutes. LPS and NPS corals need time to extend polyps and capture particles. Dropping flow to a minimum during feeding gives coral mouths a chance to intercept the plankton before it cycles past into the skimmer or filter.
• Dose near the coral, not just into open water. A target-fed squirt of Ocean Plankton near each coral head is more efficient than a broadcast dose. The concentrated formula means a small amount directed at your most demanding corals goes further than the same volume poured into the current.
• Combine with a larger-particle Fauna Marin coral food for NPS corals that need bigger prey. The 0.5–1.0mm particle is ideal for many LPS species, but certain NPS corals like sun corals and tubastrea prefer slightly larger food items. Running Ocean Plankton alongside a product like Fauna Marin Coral Sprint covers both particle size ranges in the same feeding session.
