Discosoma
Discosoma is a genus of mushroom corals in the family Discosomatidae. They are commonly known as “shrooms” or “discosoma mushrooms” in the aquarium trade. These corals are widespread throughout the Indo-Pacific region and can be found in a variety of habitats, including coral reefs, lagoons, and seagrass beds.
Characteristics
Discosoma corals are characterized by their fleshy, mushroom-shaped polyps, which can range in size from a few millimeters to several centimeters in diameter. They are typically brightly colored, with hues of red, orange, green, purple, and brown being common. Each polyp has a central mouth surrounded by tentacles, which are used for feeding and defense. The tentacles can be smooth or have stinging nematocysts, which are used to paralyze prey.
Habitat
Discosoma corals prefer shallow, well-lit areas with strong water currents. They are often found growing on rocks, coral rubble, and seagrass. They are also known to colonize artificial structures, such as docks and piers.
Reproduction
Discosoma corals reproduce both sexually and asexually. Sexual reproduction occurs when polyps release sperm and eggs into the water, which then combine to form larvae. Asexual reproduction occurs when polyps bud off from the parent polyp, creating new polyps. This process can be very rapid, leading to the formation of large colonies.
Aquarium Use
Discosoma corals are popular in the aquarium trade due to their bright colors and ease of care. They are relatively tolerant of a wide range of water parameters and are relatively easy to feed. However, it is important to note that some Discosoma species can be aggressive and can outcompete other corals for space.
