The Rhodactis rhodostoma, commonly known as the Mushroom, is a fascinating and popular coral species among marine aquarists. This striking coral is known for its unique appearance, resilience, and ease of care, making it a favorite for beginner and experienced reef tank enthusiasts alike.
Description & Characteristics
The Rhodactis rhodostoma is distinguished by its characteristic mushroom-shaped appearance, with a fleshy, dome-shaped body and a wide, flattened oral disk. Its vibrant colors, ranging from deep red to orange and brown, further enhance its appeal. The Mushroom can grow to a maximum size of 6 inches in diameter, making it a relatively compact coral suitable for various aquarium sizes.
Habitat and Occurrence
The Rhodactis rhodostoma thrives in shallow tropical waters, typically found in the Indo-Pacific region. This coral prefers protected areas with minimal wave action and abundant light. The Mushroom can be found in a variety of marine zones, including shallow reefs, lagoons, and seaward reefs.
Taxonomy
The Rhodactis rhodostoma belongs to the Class: Hexacorallia, Order: Corallimorpharia, and Family: Discosomidae. This classification reflects its unique characteristics, such as its polyp structure and its close relationship to other mushroom corals.
Feeding
The Rhodactis rhodostoma primarily feeds on phytoplankton, plankton, and zooplankton, which it captures using its tentacles. Additionally, it benefits from a symbiotic relationship with zooxanthellae, microscopic algae that reside within its tissues. These algae provide the coral with energy through photosynthesis, enhancing its growth and overall health. This symbiotic relationship highlights the importance of providing adequate light for the Rhodactis rhodostoma in an aquarium setting.
