Tigriopus californicus Copepods – “Big Red Copepod”

Our Tigriopus californicus copepods—known to many reef hobbyists as the “Big Red Copepod,” “Tig,” or “Tiger Copepod”—are a vibrant, nutrient-dense live food for reef aquariums. These bright red copepods are loaded with astaxanthin—a natural pigment and antioxidant that restores faded fish colors to their vivid, wild brilliance. Their larger size (250–1500 microns) and jerky, stop-and-go swim pattern make the Big Red Copepod irresistible to even the pickiest marine fish.

How the Big Red Copepod Benefits Your Reef

Its larger size makes it easy prey for fish, while constant movement stimulates hunting behavior. This not only boosts fish activity but also ensures they receive a diet rich in fatty acids and antioxidants. Whether you call them Tigriopus, Tig, Tiger Copepods or Big Red, they’re a powerhouse food source your reef will thrive on.
