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.

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.

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.
Buying considerations
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.
Questions answered
Start with at least 2000-5000 pods for a 50-gallon system. Smaller quantities work but take longer to establish a self-sustaining population.
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.
Copepods consume phytoplankton, detritus, and biofilm. A refugium with macroalgae provides both food and shelter. Supplementing with phytoplankton paste or drip accelerates population growth.
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.
