Care guide
Keeping Euphyllia in a reef tank
Torch coral is the most aggressive of the Euphyllia and needs the most room. Euphyllia glabrescens carries long, flowing tentacles tipped with a contrasting colour, each polyp rising from its own tube-like skeletal branch. Torches will sting other Euphyllia — including other torches of a different colour morph — so treat the usual advice about Euphyllia coexisting with some caution here.
Lighting for Gold Torch Coral
Moderate light is plenty, and this genus is easy to overdo. Under too much intensity the polyps stay tightly withdrawn and the tissue pales; under appropriate light they inflate well beyond the footprint of the skeleton. This particular frag is rated for medium light — roughly 100–200 PAR, around the middle of the rockwork.
Water flow
Gentle to moderate, indirect flow lets the polyps inflate fully. Strong direct current keeps them permanently deflated, and over time that suppressed extension shows up as stalled growth. Flow for this frag should be moderate and variable.
Placement and tank mates
Sand bed or lower rockwork. Semi-aggressive, sweeper tentacles.
What to watch for
Give a torch six inches of clear water in every direction, more than any other coral in this catalogue. Its sweepers extend furthest at night, and torch-versus-torch aggression between different morphs is a common and expensive lesson.
