Aussie Gold Torch Coral
Overview
Aussie Gold Torch Coral has long, waving tentacles with bright gold tips and contrasting darker stalks. Euphyllia glabrescens is a large-polyp stony coral with a branching skeleton; it prefers moderate lighting and moderate to gentle, indirect water flow. It relies on symbiotic algae for energy but benefits from occasional meaty or particulate foods, which can support growth and maintain coloration. Give it space, as its sweeper tentacles can sting nearby corals, and place it where tissue won’t rub on rockwork.

Frequently Asked Questions
About the Aussie Gold Torch Coral
-
How do I keep the “Aussie gold” coloration from fading in Euphyllia glabrescens?
Maintain PAR around 120–180 with a blue-heavy spectrum (14–20K). Keep nutrients detectable (NO3 5–15 ppm, PO4 0.03–0.08 ppm); ultra-low levels can wash out gold tones. Avoid excessive white light and sudden increases in intensity. Stable alk 8–9 dKH, Ca 420–460, Mg ~1350, and moderate, indirect flow support pigment retention and full polyp extension. -
My torch’s tentacles look shorter and thin—what’s the likely cause?
Common causes include too much direct flow, abrupt alkalinity swings, or nutrient starvation. Check for pests and early brown jelly (mucus, foul smell). Reduce laminar blast to a gentle, oscillating flow. Stabilize parameters, feed small meaty foods weekly, and consider an iodine/broad-spectrum coral dip if recession starts. Improve gas exchange and maintain steady temperature. -
Can it touch other Euphyllia like hammers or frogspawn safely?
Not reliably. Torches often sting even closely related Euphyllia. Give 10–15 cm (4–6 in) clearance and avoid direct contact. Night sweeper tentacles can reach far and cause slow tissue loss in neighbors. If mixing with softies or leathers, run fresh carbon and ensure strong export, as chemical warfare can trigger retraction or polyp bailout in torches. -
Why is the base receding while the tips still look fine?
This often points to chronic stress at the skeleton-tissue interface: fluctuating alkalinity, bacterial infection, or shading causing low flow at the base. Improve random flow around the stalk, verify no detritus buildup, and stabilize alk/pH. Perform an iodine dip, gently turkey-baste debris, and slightly increase PAR without shocking. If localized, consider cutting above the recession line.
