Coral Food Mix:

This formulated frozen food is a very special mixture of tiny Zooplankton critters mixed with three types of Phytoplankton, - Spirulina, Tetraselmis.  The Zooplankton portion includes Rotifers, Cyclops and Moina.  We add a special mix of Vitamins, Amino Acids and Trace Elements.  The result is a complete and nutritious diet for all types of live corals (stony corals & soft corals, SPS & LPS) as well as other filter-feeding marine invertebrates.

This food is literally the best coral food on the market – made of fresh and nutritious ingredients; and affordable as well!   It’s the “Unsung Hero” and available to coral-growing hobbyists everywhere. Because of its comprehensive formulation, this product covers all the bases in feeding the complex reef environments in the hobby today as the food particle size range covers the entire spectrum of specialized requirements for corals and other filter-feeding invertebrates.  

At the microscopic end of the spectrum, the phytoplankton, Tetra, and Nanno, are uni-cellular micro-algae with a size range of 5 to 15 microns per cell.  These tiny cells move around on their own and “eat up” the nutrients in the environment – phosphates, nitrates, ammonia, silicates, vitamins, trace elements, etc..  They reproduce rapidly and create a green water BLOOM in the laboratory or in greenhouses or outdoor containers and ponds.  The algae are harvested at the peak of their bloom and usually filtered or centrifuged down to a concentrated paste.  At V2O FOODS, we use this “paste” as a specialized ingredient in the CORAL FOOD and various other formulas.

In the marine reef aquarium, the phytoplankton is most valuable for feeding filter-feeding invertebrates such as sponges, tunicates, bivalves (clams, mussels, flame scallops), tiny crustaceans, Zooplankton (copepods), planktonic larvae, corals, etc..  

Spirulina was previously considered a blue-green alga -  a type of photosynthetic phytoplankton composed of many tiny cells strung together in a long spiral string.  Nowadays they are classified as edible gram-negative cyanobacteria. Their filamentous cell structure makes them larger and more difficult to consume for certain filter-feeders.  However, their cell walls are soft and for those that can consume them, they are extremely nutritious due to their high protein and high carotenoid pigment content.

The Zooplankton comprise the “next size up” food items.  In the V2O CORAL FOOD, this means Rotifers, Cyclops copepods, and Moina (sometimes Daphnia) Cladocerans.  In nature, these feed constantly on phytoplankton blooms and therefore are “gut-loaded” with the rich pigment/protein nutrition of the tiny algae cells.   In a marine aquarium, these tiny zooplankton animals provide an excellent food for CORALS and other filter-feeding invertebrates. Acropora corals, Zoanthids, Goniopora and Dendronephthya for example, can reach out with extended polyps and grab the zooplankton as they nonchalantly swim within range of the tenacious tentacles.  In addition to feeding corals, These zooplankton critters are the ultimate coloration-producing food for small, brightly colored marine tropical fish.

For practical purposes, the zooplankton in V2O CORAL FOOD is primarily a by-product of the vast region of outdoor pond aquaculture in northern coastal China.  Rotifers, Cyclops and Moina often occur naturally during the cycling of ponds. After the ponds are harvested, drained, and then re-filled with nutrient-rich water, phytoplankton will “bloom” into a large population within the ponds.  They will often turn the water green, brown, or red when the bloom is at its peak. The zooplankton, in turn, will then start their own bloom, feeding on the phytoplankton and reproducing into millions, trillions and Gizillions of tiny nutritious little animals, now ready for harvesting as a specialty food source.

It is interesting to ponder how many Rotifers or Cyclops are actually required to make up a ton of frozen product, or even one 1kg of product.   It so happens that northern coastal China is one of the few areas in the World where this Zooplankton can be grown in such large numbers. It would probably take an entire small pond full of animals in order to fill one-kilogram package of drained rotifers.  Imagine the tremendous volume required to supply the tons of food for the entire aquarium industry – it’s mind-boggling! As aquarists, we are very fortunate to have availability of these products….it’s a windfall bonus to us from the aquaculture pond farming of fish and shrimp which are grown to provide food for humans throughout the world.
