Tigriopus copepods are small, hardy crustaceans around 2mm long and commonly used in home aquariums as a highly nutritious live food source for fish, corals, and other marine invertebrates. They are the largest copepods we offer and help in maintaining tank cleanliness by consuming detritus, algae, diatoms, dinoflagellates and waste. Our product, "Tigriopus - Live Zooplankton" is a premium bottled culture of Tigriopus copepods, specially cultivated on site to ensure maximum health and nutritional value.
