Toxic Green Torch Coral – Euphyllia glabrescens – High-Impact Fluorescence and Flow for Reef Aquariums
The Toxic Green Torch Coral (Euphyllia glabrescens) is a visually striking LPS coral prized for its intense neon green tentacles and gentle blue tips. Under actinic or reef-blue LED lighting, this coral radiates with high contrast and vibrancy, becoming an instant focal point in any marine display.
Each long, whip-like tentacle moves rhythmically with the current, delivering lifelike flow and adding animation to the aquascape. This variety of Torch Coral is especially popular for its visual intensity and reliable expansion in stable reef systems.
This coral thrives in low to moderate lighting and requires moderate, indirect flow for optimal tentacle extension. As a semi-aggressive species, it should be placed with adequate spacing from other corals to prevent tissue damage from its long sweeper tentacles.
The Toxic Green Torch is ideal for aquarists looking to build Euphyllia gardens or seeking a standalone centrepiece that combines colour, motion, and manageable care.
Lighting Requirements:
-
Thrives under low to moderate lighting (PAR 100–150)
-
Best fluorescence observed under actinic or blue-spectrum LEDs
-
Slowly acclimate to higher lighting intensities if needed
Water Flow:
-
Requires gentle to moderate, indirect flow
-
Avoid direct, forceful current to prevent polyp retraction
-
Ensure soft, natural movement of tentacles
Aquarium Compatibility:
-
Suitable for medium to large reef aquariums
-
Semi-aggressive – allow 10–15 cm spacing from other corals
-
Excellent as a showpiece or component in Euphyllia-dedicated zones
-
Performs best in tanks with stable parameters and peaceful inhabitants
Feeding Notes:
Photosynthetic, but will benefit from occasional feeding:
-
Mysis shrimp
-
Brine shrimp
-
Marine coral blends
Feed 1–2 times per week for enhanced colour and growth.
