Brightwell Aquatics Zooplanktos-L is a highly concentrated suspension of zooplankton ranging in size from 500 to 2,000 microns (2mm). This makes it the ideal food for a variety of aquatic organisms such as stony corals, clams, larval crustaceans, juvenile fish, and planktivorous and microinvertebrate-predatory fish. Formulated by a marine scientist, this suspension contains a variety of amino acids, omega-3 fatty acids, vitamins, and xanthophyll, making it extremely nutritious for its consumers. In addition, a proprietary amino acid has been added to promote vivid coloration in corals and other marine invertebrates. With a small percentage of vitamin-C added, this suspension also aids in the health and coloration of recently propagated or fragmented corals. Zooplanktos-L can be used in combination with other planktonic suspensions for a complete range of sizes to feed filter-feeding
