🔥 Torch Coral – Description & Care Guide
🪸 Description
Torch Coral (Euphyllia glabrescens) is a Large Polyp Stony (LPS) coral known for its long, flowing tentacles that resemble flames or torches — giving it its common name. It’s highly prized for its motion, color, and bold appearance in reef tanks.
Key Features:
-
Polyp Shape: Long, tubular tentacles with glowing tips (white, gold, green, or neon)
-
Color Morphs: Green, gold, purple, orange, pink, “holy grail,” and “dragon soul”
-
Growth Form: Branching or wall (single base); branching is easier to frag
-
Behavior: Aggressive — long stinging tentacles can harm nearby corals
-
Nickname: One of the “Big 3” Euphyllia (along with Hammer and Frogspawn)
🧪 Tank Requirements
| Parameter | Ideal Range |
|---|---|
| Lighting | Moderate to high (PAR 80–200) |
| Flow | Moderate, indirect |
| Temperature | 75–80°F (24–27°C) |
| Salinity | 1.025–1.026 SG |
| Alkalinity | 8–10 dKH |
| Calcium | 420–460 ppm |
| Magnesium | 1250–1350 ppm |
| Nutrients | Nitrate: 5–15 ppm; Phosphate: 0.03–0.1 ppm |
💡 Lighting Tips
-
Moderate lighting enhances color and health.
-
Acclimate slowly to avoid bleaching, especially under LEDs or T5s.
-
Blue-dominant spectrum brings out fluorescent tips.
🌊 Flow Requirements
-
Prefers moderate, indirect flow.
-
Tentacles should gently wave — too much flow causes retraction or damage.
-
Avoid direct blasts from powerheads.
🍽️ Feeding
Torch corals are photosynthetic, but target feeding improves growth and coloration.
-
Best Foods: Mysis shrimp, Reef-Roids, Coral Frenzy, amino acids
-
Method: Target feed near tentacles or mouths 1–2 times per week
-
Benefit: Encourages faster branching and tissue health
🧼 Care & Placement
-
Aggression: High — sweeper tentacles can reach 6+ inches
-
Placement: Mid to lower tank, with at least 6 inches of space from other corals
-
Fragging: Branching torches are easy to frag; wall varieties are more delicate and prone to infection when cut
⚠️ Common Issues
| Issue | Cause | Solution |
|---|---|---|
| Tissue loss (brown jelly) | Bacterial infection | Frag healthy parts and treat with iodine |
| Polyp retraction | Too much light/flow or stress | Adjust placement and test water quality |
| Tip burning or recession | Alk or salinity swings | Stabilize parameters |
| Color fading | Nutrient deficiency or low PAR | Feed more and/or increase lighting |

🔥 Popular Torch Coral Variants
| Name | Color Features | Notes |
|---|---|---|
| Holy Grail | Gold/yellow tips, neon green base | Very rare and expensive |
| Dragon Soul | Bright gold tips, dark base | High-end collector coral |
| Indo Gold | Golden tentacles | Sensitive but stunning |
| Green Torch | Classic neon green with white tips | Hardy and widely available |
🌿 Tips for Success
-
Stable parameters are key — Euphyllia corals don’t like swings.
-
Observe tentacle length before adding neighbors.
-
Do not touch tentacles — they are sensitive and sticky.
-
Use coral dips (e.g., iodine) if fragging or treating for infection.
