Overview

Star polyps (genera Clavularia, Briareum) are colonial soft corals whose purple-to-brown stolons produce numerous star-shaped white or green polyps across rock surfaces. Native to Indo-Pacific reefs, they spread rapidly as thin mats and are among the hardiest corals for beginners. They thrive under moderate to strong lighting (150–300 PAR) with moderate flow, displaying beautiful fluorescent green coloration when fully open. Their rapid growth demands regular trimming to prevent overgrowing neighboring corals. Fragging is simple—attaching a piece to a new rock surface is sufficient for propagation.

Care Specifications

Care Points

• Lighting—Medium to strong LED lighting
• Flow—Moderate flow
• Water Quality—Tolerates some water quality variation
• Growth—Spreads aggressively — can overtake rockwork
• Notes—May overgrow other corals — place isolated

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.

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.
