Common name: Coralline Algae

General information

Mesophyllum mesomorphum, commonly known as coralline algae, is a species of red algae that plays a crucial role in reef ecosystems. It is characterized by its hard, calcareous structure which often appears in various shades of pink, purple, or red. This algae is not just a single species but represents a group of species within the coralline algae family. It contributes significantly to the construction and stability of coral reefs by depositing calcium carbonate, which cements together other organisms and substrate.

Coralline algae are also known for their ability to outcompete nuisance algae by covering available surfaces, thus preventing the spread of less desirable species. Their presence is often an indicator of a healthy reef environment.

Care

Keeping Mesophyllum mesomorphum in a reef aquarium requires stable water conditions with adequate levels of calcium, magnesium, and alkalinity to support its calcification process. Adequate lighting and water flow are also essential to mimic its natural habitat conditions. It's important to maintain a clean tank with low nutrients to prevent the overgrowth of non-calcifying algae that can outcompete coralline algae.

Symbiosis

While Mesophyllum mesomorphum does not engage in the more dynamic forms of symbiosis seen in other reef organisms, it does play a foundational role in the reef ecosystem. It provides a substrate for various invertebrates and microorganisms, and its calcareous structure offers protection and attachment points for sessile organisms.

Habitat

Mesophyllum mesomorphum is found in a wide range of marine environments, from shallow to deep waters, and is particularly abundant in coral reef ecosystems. It thrives on hard substrates where it receives ample light for photosynthesis, although some species can also be found in slightly shaded areas or at greater depths.
