Order

Common name: Coralline Algae

Scientific name: Corallinales

Corallinales, commonly known as coralline algae, are an order of red algae that are widespread in marine environments. They are notable for their hard, calcareous deposits within their cell walls, which give them a stony appearance. These algae play a crucial role in reef-building and are beneficial in reef aquariums for their ability to outcompete nuisance algae and provide a natural, attractive look. They come in various colors, including pink, purple, and red, and can encrust surfaces or form branching structures. Coralline algae are important for maintaining water quality and providing habitat for small invertebrates.
