Euphyllia glabrescens is found across the Indo-Pacific. Distinguished from Hammer (E. ancora) by single tentacle tips ending in a small ball, vs Hammer's hammer-shaped split tip. Torch tentacles are longer, more flowing, and produce dramatic visual movement.
The hobby distinguishes Torches by origin:
Torches sting. Their sweeper tentacles can extend 6-8 inches at night and chemically attack any coral within reach. Plan for 6+ inch separation from non-Euphyllia neighbors. Other Euphyllias (Hammer, Frogspawn) generally co-exist peacefully due to similar chemistry.
Place mid-tank with low-to-moderate flow. Direct power head blast prevents tentacle extension and stresses the coral. Indirect, gentle flow produces the flowing tentacle expression Torches are loved for.
Euphyllia genus is uniquely susceptible to "brown jelly disease" - rapid tissue dissolution producing brown mucus around the dying head. Spreads to neighboring polyps fast. Treatment:
The Torch market has experienced significant pricing volatility. Holy Grail Torch traded at $5,000+ per head in 2020-2022, has come down to $1,500-3,500 as captive propagation increased. Watch market trends before paying premium.
Each species has its own deep care guide with photos, parameters, diet, compatibility, breeding notes, common diseases, and a 4-question FAQ. Vendor listings live alongside the educational content.
