The Blue Mushroom, also known as the Discosoma Mushroom or Blue Disc Mushroom, is a species of mushroom coral commonly found in the marine aquarium trade. They have a distinctive blue coloration and are relatively easy to care for, making them a popular choice for beginner and experienced hobbyists alike. Blue Mushrooms are relatively small and grow in colonies, with each individual mushroom ranging from about 1 to 3 inches in diameter. They prefer moderate to low lighting and moderate water flow in the aquarium, and can be fed small pieces of meaty foods like shrimp or mysis shrimp. In the wild, Blue Mushrooms are found throughout the Indo-Pacific region, including the Great Barrier Reef, and are typically found in shallow waters up to 30 meters deep. They can be found on various substrates, including rocks and coral rubble, and are known to reproduce both sexually and asexually.
