Hypnea pannosa

Blue Hypnea (Hypnea pannosa)
Blue Hypnea is a striking and fast-growing macroalgae prized for its shifting shades of color. Under intense light and flow it takes on brilliant blue to teal tones, while in lower light it can appear more subdued. Under reef-blue lighting, this macro often shows as deep red, making it a dynamic and ever-changing addition to your tank.

Care Guide:

• Light: Thrives under intense lighting, but adapts to lower light

• Flow: Prefers strong flow, but will adjust to gentler currents

• Placement: Rockwork or substrate in display or macroalgae-specific tanks

• Experience Level: Beginner-friendly

• Growth Rate: Fast grower

• Benefits: Stunning coloration, nutrient export, hardy and adaptable

• Portion Size: Roughly a golf ball–sized piece per order

⚠️ Coloration Note:
Blue Hypnea’s vibrant blue hues are highly dependent on lighting conditions and are not guaranteed. Specimens may range from red to teal to bright blue, depending on your setup. We always do our best to send a healthy, colorful piece.
