Why you should trust this review
Reef aquarium microfauna management requires specific knowledge of species selection, live shipping conditions, and refugium setup. I maintain a reef system with a dedicated refugium and have seeded copepod cultures multiple times, tracking establishment success across different conditions and products.
How we tested copepod cultures
We evaluated live arrival rate by counting live versus dead specimens immediately upon receipt. We then introduced cultures to an established refugium and monitored population density at 30, 60, and 90 days using a dipnet sample and count method.
Who should buy copepod cultures?
Reef keepers who want to support a healthy microfauna ecosystem, anyone setting up or restoring a refugium, and specifically anyone keeping mandarin dragonets, scooter blennies, or other finicky eaters that rely on copepods as a primary food source.
AlgaGen Tisbe Biminiensis: best for refugium seeding
AlgaGen is one of the most established live marine invertebrate suppliers and their copepod cultures arrive in consistently good condition. Tisbe biminiensis is a robust species that tolerates a wide salinity and temperature range, establishes quickly in a refugium with macroalgae, and reproduces rapidly. A 16 oz bottle added to an established refugium will show visible population growth within 30 days.
Algae Barn Ultra Reef Blend: best for mandarin fish
The Algae Barn blend includes both Tisbe and Tigriopus species. Tigriopus is larger and more visible to fish, making it more effective as a direct food source for mandarin dragonets. The blended culture provides both small species for refugium establishment and larger species for fish feeding.
What to look for when buying copepods
Species selection matters. Tisbe biminiensis is the best refugium seeder. Tigriopus californicus is best for fish feeding. Multi-species blends cover both functions.
Live shipping handling is critical. Order only from suppliers that ship overnight with temperature protection appropriate to the season. Open the package immediately and acclimate properly.
Refugium preparation before adding pods. Macroalgae like cheato provides both food and shelter. Add phytoplankton to the refugium before and after introducing pods to maximize survival and establishment.
Frequently asked questions
How many copepods do I need to seed a refugium?+
Start with at least 2000-5000 pods for a 50-gallon system. Smaller quantities work but take longer to establish a self-sustaining population.
Can copepods live in the main display tank?+
Yes, but a refugium with chaeto or other macroalgae provides a refuge from predation and supports a much larger, self-sustaining population that continuously replenishes the display tank.
What do copepods eat in a reef tank?+
Copepods consume phytoplankton, detritus, and biofilm. A refugium with macroalgae provides both food and shelter. Supplementing with phytoplankton paste or drip accelerates population growth.
How do I feed a mandarin fish with copepods?+
Establish a healthy refugium population first. Mandarins need a continuous supply, not occasional feedings. Some hobbyists also use a separate copepod culturing vessel to supplement the refugium output.
