Lyngbya
Lyngbya sp.
Dark, wiry filaments of cyanobacteria that form dense mats — often mistaken for BBA. Unlike true algae, it can fix atmospheric nitrogen, meaning low nitrogen levels do not suppress it. Produces toxins harmful to invertebrates. Requires the same treatment as blue-green algae: blackout, H₂O₂ treatment, and improved flow.

Maiden's Hair
Chlorodesmis fastigiata
Vivid blue-green turf-like tufts of very fine filaments — a common sight on Indo-Pacific reefs. In captivity it can spread across rockwork quickly. Produces terpene compounds that deter most grazers. Interesting as a biotope element but can become a nuisance if left unchecked.

Marimo Moss Ball
Aegagropila linnaei
Beloved velvety-green spheres of filamentous green algae — not a moss at all. Forms naturally in cold lakes where wave action rolls colonies into balls over decades. A low-maintenance aquarium icon that grows extremely slowly. Rotate occasionally for even light exposure.
