Overview
Organ pipe coral (Tubipora musica) is a unique octocoral that builds a bright red calcium carbonate skeleton of parallel tubes resembling a pipe organ—unusual among soft corals. Native to shallow reefs of the Indian and Pacific Oceans, living colonies appear green, blue, or purple as the skeletal tubes are concealed by expanded polyps bearing eight feathery tentacles. Colonies grow in dome shapes up to 3 m across. In aquaria, moderate lighting (150–250 PAR) and gentle to moderate flow are optimal; turbulent currents cause polyp retraction. Its striking appearance has driven heavy collection pressure for both aquaria and the souvenir trade, highlighting the importance of sustainable sourcing.

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.
