Common name: Ceramiales

Ceramiales is an order of red algae that is well-represented in marine aquariums, particularly for its role in nutrient cycling. Members of this order, such as the genera Ceramium and Callithamnion, are often used as ornamental macroalgae. They can provide a natural and aesthetically pleasing way to control nutrients like nitrate and phosphate. These algae are also important as a habitat for small invertebrates and as a natural food source for herbivorous fish. Hobbyists appreciate their diverse forms and colors, which can range from bright reds to deep purples, adding a splash of color to the reef tank.
