AI illustration Overview
The torch coral is a Euphyllia with long, luminous tentacles tipped with glowing rounded ends that flow like a living flame; prized colour morphs sell for very high prices. It is stunning and hardy, but also the most aggressive of the group. (Euphyllia glabrescens.)
Origin & Habitat
Indo-Pacific reefs, on slopes in moderate light and gentle flow.
Appearance
Long, tapering tentacles ending in glowing single tips, in gold, green, and rare 'designer' morphs; each head sits on a stony branch.
Placement & Temperament
The most aggressive Euphyllia - keep it well away from ALL other corals, including other Euphyllia, since torches will sting even hammers and frogspawn. Allow 15-20 cm of clear space.
Tank & Water Conditions
Salinity 1.024-1.026, 24-27°C, stable alkalinity 8-11 dKH, calcium 400-450, magnesium 1300-1350.
Lighting & Flow
Moderate light (about 100-150 PAR) and gentle flow so the long tentacles can extend fully.
Feeding
Photosynthetic plus occasional target feeding of small meaty foods for faster growth and new heads.
Health & Growth
Hardy but sensitive to flow and stability, and prone to brown jelly if stressed. Torches can be finicky to settle - give a new one a stable, calm spot and time.
Pros & Cons
Pros
- Stunning flame-like movement
- Prized, high-value colours
- Adds new heads over time
Cons
- Most aggressive Euphyllia: isolate it
- Can be slow to settle
- Brown jelly risk when stressed

Torch Coral - frequently asked questions
Can I keep a torch coral next to my hammer?
Better not to. Torches are aggressive even toward other Euphyllia and will sting hammers and frogspawn. Give a torch its own space, 15-20 cm from anything.
Why is my new torch not opening?
Torches often sulk after a move. Give it stable water, gentle flow and a fixed spot, and be patient - it can take a couple of weeks to fully extend.
