Toadstool Coral
Sinularia sp.May, 1898Genus
Branching soft coral that is hardy with diverse color variations. Easy to frag and propagate.

Names & Synonyms

- Commonカタトサカ
Overview
Toadstool coral (genus Sarcophyton, family Alcyoniidae) is a large soft coral with a distinctive mushroom-shaped cap covered in dense polyps, native to shallow reef slopes and reef crests across the Indo-Pacific. Colonies can exceed 30–60 cm in diameter. Coloration ranges from white and cream to green. This hardy species tolerates a wide range of conditions, thriving under low to moderate lighting (100–200 PAR) and moderate flow. It periodically closes its polyps and sheds its outer skin—a normal detoxification process accompanied by brown mucus secretion. Fragging is easy, making it an excellent first coral for beginners.

Soft Coral Soft Rot Disease and Tissue Collapse | Slime Secretion Abnormalities, Infection Treatment and Prevention
Soft Rot Disease in soft corals is a fatal disease in which the flexible skeletal portions rapidly decompose due to bacterial infection. The disease's onset involves multiple environmental factors, with rapid water temperature fluctuations (±3°C or greater), nutrient excess, water quality deterioration, and physical stress to the specimen serving as primary triggering factors.

Nutrient Management in Soft Coral Tanks | Balancing Nitrates and Phosphates with Zooxanthellae and Trace Elements
While soft corals are often said to require less rigorous nutrient management than SPS corals, extreme eutrophication or oligotrophy can lead to polyp retraction and color loss. Let's clarify how to think about balancing nitrates, phosphates, zooxanthellae, and trace elements.
