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.

Ulva lactuca
Bright green, tissue-thin sheets of macroalgae familiar on coastlines worldwide. Fast-growing nutrient exporter and a relished food for tangs, urchins, and rabbitfish. Tolerates a very wide temperature and salinity range. Can become weedy if not harvested — keep export-focused.
