Hair Algae
Oedogonium sp.
Family: Oedogoniaceae
📍 Worldwide in freshwater
Fine, bright-green strands that drape over plants and hardscape. One of the most common new-tank algae — usually caused by excess light, nutrient imbalance, or lack of fast-growing plants competing for nutrients. Nerite snails, Amano shrimp, and Florida Flagfish make short work of it.
