Coralline algae are red algae in the order Corallinales. They are characterized by a thallus that is hard because of calcareous deposits contained within the cell walls. The colors of these algae are most typically pink, or some other shade of red, but some species can be purple, yellow, blue, white, or gray-green.
Mature live rock in a marine aquarium, well encrusted with a variety of coralline algae. Live rock is rock from the ocean that has been introduced into a saltwater aquarium. Along with live sand, it confers to the closed marine system multiple benefits desired by the saltwater aquarium hobbyist.
The coralline algae lives in the mid-tide and higher level pools, occasionally exposed to air. [4] The coralline algae mostly grows on hard rock surfaces and was not found on any limestone or slate rock. [4] It can also be found growing on the shells of mollusks that live in the same area, however the algae was physically reduced on the shells. [4]
A tide pool or rock pool is a shallow pool of seawater that forms on the rocky intertidal shore. These pools typically range from a few inches to a few feet deep and a few feet across. [ 1 ] Many of these pools exist as separate bodies of water only at low tide , as seawater gets trapped when the tide recedes.

There are many variations of crustose, including Crustose Coralline Algae (CCA), found in three different habitats; flat, crest and slope reef. [8] CCA are highly dependent on sunlight to grow in abundance, and their growth increases productivity. CCA acts as the main food source for certain fish including parrotfish and Scarus trispinosus.

This calcified genus of Coralline algae encrusts hard surfaces, helping to build reefs by cementing dead coral together. It is pink in coloration and grows plate-like projections, often with white edges. If it has not already been introduced on live rock, fragments of the algae may be placed in an
An arrangement of live rock forms the main structure of this aquascape, and it is populated by corals and other marine invertebrates as well as coralline algae and macroalgae, which together serve much the same aesthetic role as freshwater plants. [33] [34] Lighting plays a particularly significant role in the reef aquascape.
