Known for its long, flowing tentacles tipped with contrasting colours, it resembles flickering flames under aquarium lighting. Native to the Indo-Pacific, the Torch Coral thrives in reef tanks when provided with stable water conditions and proper care. Behaviour and Habitat Torch Corals are semi-aggressive and can extend their tentacles several centimetres to sting nearby corals or invertebrates. Place them in an area where they won't come into contact with other coral species. In the wild, they are found in reef slopes and lagoons, often in moderate water movement zones. They use their tentacles for both defense and capturing prey, but they primarily rely on their symbiotic zooxanthellae algae for sustenance. Placement and Tank Requirements Torch Corals prefer moderate lighting and water flow. Avoid strong currents, which can cause their tentacles to retract or become damaged. Ideal placement is mid-level in the aquarium, where they can receive sufficient light and movement. Provide plenty of space between Torch Corals and other species to prevent stinging incidents. Ensure the tank has stable parameters, as Torch Corals are sensitive to swings in water chemistry. Diet Torch Corals are photosynthetic, deriving most of their energy from light. However, they benefit from supplemental feeding, which can promote faster growth and vibrant coloration. Feed them 1-2 times weekly with: Mysis shrimp Brine shrimp Phytoplankton Specialized coral foods Use a turkey baster or coral feeder to target-feed their tentacles. Care Tips Monitor calcium (400-450 ppm), magnesium (1250-1350 ppm), and alkalinity (6-12 dKH) to support skeleton development. Maintain consistent salinity and temperature to prevent stress. Avoid direct contact with aggressive corals or fast-growing soft corals that could overshadow the Torch Coral. Compatibility Torch Corals can coexist with other peaceful corals, provided they are placed at a safe distance. They are also reef-safe and will not harm fish or invertebrates unless directly touched. Avoid placing them with overly aggressive or invasive coral species. Final Thoughts The Torch Coral is a captivating addition to reef aquariums, offering mesmerizing movement and bold coloration. With proper placement, lighting, and care, this coral will thrive and become a focal point in any reef setup. Its semi-aggressive nature requires thoughtful planning, but the effort is well worth the stunning display it provides.
