Sargassum

Sargassum natans

Family: Sargassaceae

📍 Sargasso Sea and tropical Atlantic

Ask Finn

The iconic free-floating brown macroalgae of the open ocean — forms dense golden-brown mats in the Sargasso Sea. In aquariums it anchors to rock or tumbles freely. Hosts an entire ecosystem of cryptic animals (pipefish, frogfish, shrimp) in the wild. Challenging to keep long-term but impressive in large displays.
