Genus
Common name: Green Finger Algae
Scientific name: Udotea
Udotea is a genus of green macroalgae commonly found in reef aquariums, known for its fan-like appearance. It is a beneficial algae that can help with nutrient export and provides a natural food source for herbivorous fish and invertebrates. Udotea species grow best in moderate lighting and water flow, and they can be a good indicator of water quality, as they tend to thrive in well-maintained systems. They are non-invasive and can add a unique aesthetic to the tank.
