Fuzz Algae

Stigeoclonium sp.

algaefreshwater

Short, fuzzy green tufts — typically 2–5 mm — that appear on the edges of plant leaves, hardscape, and equipment. One of the most common algae in newly planted tanks. Easily grazed by Amano shrimp, Otocinclus, and nerite snails. Caused by light excess or inconsistent CO₂ early in a tank's life. Usually resolves as the tank matures.
