Euphyllia glabrescens, commonly known as the Black Torch coral, is a popular Large Polyp Stony (LPS) coral prized for its dramatic, waving tentacles and contrasting tips that add vibrant movement to reef aquariums.
This frag features a single head (1 hd.) of cultured coral, grown under controlled conditions to ensure health and vitality. It is an excellent choice for marine hobbyists with some experience in coral husbandry.
Care Level
Moderate – suitable for aquarists with basic knowledge of coral care and stable reef tank conditions.
Lighting Requirements
Moderate to high lighting is recommended. LED, T5, or metal halide lighting systems that provide a PAR range of approximately 100-250 µmol/m²/s will support optimal growth and coloration.
Water Flow
Moderate, indirect water flow is ideal. Strong direct currents can cause the delicate tentacles to retract or sustain damage, while too little flow may lead to detritus accumulation.
Placement
Position the Black Torch coral in the middle to lower regions of the aquarium to balance lighting and flow needs. Ensure adequate spacing from neighbouring corals to prevent aggressive sweeper tentacle contact.
Diet
Primarily photosynthetic via symbiotic zooxanthellae, but benefits from occasional feeding of meaty foods such as brine shrimp, mysis shrimp, or specialised coral foods to promote growth.
Compatibility and Reef Safety
Yes, with adequate spacing. Euphyllia glabrescens can extend long sweeper tentacles that may sting nearby corals, so maintain a minimum distance of 10-15 cm from other sensitive species.
Minimum Tank Size
Recommended minimum tank size is 75 litres (20 gallons) to provide stable water parameters and sufficient space for growth.
Origin
Not Provided – cultured frag sourced from DJM Grown LPS corals.
Maximum Size
Colonies can reach up to 30 cm (12 inches) in diameter under optimal conditions.
