Zooplanktos-M Zooplankton Food Supplement for Marine & Reef Tanks

In this review of Zooplanktos-M, the bottom line is straightforward: this specialized zooplankton supplement is for marine and reef keepers who want a nutrient-dense live-feed alternative sized for corals, clams, and planktivorous fishes. The reviewer found the product notable for its concentrate of copepods in the 500-1,000 micron range and for the added proprietary amino acid meant to aid coloration. Because it does not require refrigeration and was formulated by a marine scientist, it is convenient for regular feeding routines while delivering the nutritional components many invertebrates and juvenile fishes require.

Key Features

• Size range: The 500-1,000 micron copepods are ideally sized to be consumed by many stony corals, clams, and tube worms, ensuring more efficient feeding for those animals.
• Nutrient rich: The copepods are reported to contain amino acids, omega-3 fatty acids, vitamins, and carotenoid pigments that support overall health and pigmentation of consumers.
• Coloration aid: A proprietary amino acid supplement is included to help enhance coloration in both invertebrates and fishes over routine use.
• Versatile target species: Formulation and size make it suitable for larval crustaceans and bivalves, juvenile fishes, planktivorous adult fishes, and a range of microinvertebrate predators.
• No refrigeration required: The product is stable at normal storage conditions, simplifying handling for hobbyists and reducing maintenance concerns.
• Scientific formulation: Developed by a marine scientist to emphasize nutritional value and appropriate prey size for marine aquarium feeding.

Who It's For

Zooplanktos-M is best for hobbyists maintaining reef aquariums with feeding-demanding inhabitants such as large- and small-polyp stony corals, clams, tube worms, and planktivorous fishes like anthias. It also fits advanced breeders or aquarists raising larval crustaceans and juvenile fishes that need appropriately sized mesoplankton prey.

Less suitable are freshwater hobbyists or tanks without organisms that actively feed on 500-1,000 micron prey; those users should look for products formulated specifically for freshwater species or for different prey-size profiles.

Pros & Cons

Pros

• High-quality copepod concentrate provides a nutrient-rich live-feed option for many reef species.
• Proprietary amino acid addition supports improved coloration for both invertebrates and fishes.
• No refrigeration required, making storage and use simpler for routine feedings.

Cons

• Targeted size range means it is not suitable for very small microfauna or for freshwater species, limiting universal use.
