Tetraselmis Chuii - Live

Tetraselmis chuii — Live Phytoplankton

Feed the foundation of your reef with Tetraselmis chuii, a live, single-species green phytoplankton cultured by 4th Dimension Aquatics.

Widely used in marine aquaculture, Tetraselmis provides proteins, lipids, and carbohydrates that help nourish the small organisms supporting the marine food web. It’s a versatile addition to reef feeding routines, live-food production, and home phytoplankton culturing.

Benefits & Uses

• Supports live-food cultures: A feeding option for rotifers, brine shrimp, and compatible copepod species.

• Feeds suitable filter feeders: Provides microscopic food for organisms capable of capturing and consuming its cells.

• Supports the reef food web: Nourishes small grazers and zooplankton that can, in turn, become food for larger reef inhabitants.

• Adds dietary variety: Can be used alongside other phytoplankton species to broaden your feeding routine.

• Single-species culture: A useful option for hobbyists who want to culture their own Tetraselmis or select a specific phytoplankton for feeding.
