The Hellfire Torch is a high-end color morph of Euphyllia glabrescens, prized for its neon yellow/orange tentacles with fiery red or pink tips. Like other torch corals, it has long, flowing polyps and can be moderately demanding but very rewarding.
Tank Size: 30+ gallons (larger preferred for stability)
Experience Level: Intermediate
Placement: Mid to lower tank, depending on light intensity
Aggression Level: Semi-aggressive (long sweeper tentacles)
PAR Range: 80–200 PAR
Type: LED, T5, or hybrid reef lighting
Tip:
Lower light = longer extension but potentially less intense coloration
Higher light = better coloration, but acclimate slowly
Too much light can cause bleaching; always light-acclimate new specimens.
Flow Type: Moderate, indirect, and random
Avoid direct blasting — tentacles should gently sway, not whip violently.
Excessive flow can cause tissue recession.
Stable parameters are critical for torches:
Temperature: 76–79°F
Salinity: 1.025–1.026
Alkalinity: 8–9 dKH (keep stable)
Calcium: 420–450 ppm
Magnesium: 1300–1400 ppm
Nitrate: 5–15 ppm
Phosphate: 0.03–0.10 ppm
Torch corals dislike rapid alkalinity swings more than slightly “imperfect” numbers.
While photosynthetic, Hellfire Torches benefit from occasional feeding:
1–2 times per week
Mysis shrimp, reef roids, or small meaty foods
Turn off flow during feeding for best response
Feeding can improve growth and polyp extension.
Leave 3–6 inches between this torch and other corals.
Can sting nearby LPS and even other torch varieties.
Some torches tolerate other Euphyllia species, but it’s not guaranteed.
Brown Jelly Disease
Rapid tissue decay
Requires immediate fragging and iodine dip
Bail-Out (polyp detachment)
Usually caused by stress (alk swing, poor flow, pests)
Not Opening Fully
Check for:
Excessive flow
Alk instability
Recent lighting changes
Flatworms or pests
Growth rate: Moderate
Can be fragged by cutting between skeleton branches using a bandsaw or coral cutter
Always dip after fragging
