Euphyllia yaeyamaensis – Euphyllia yaeyamaensis LPS coral with densely branched tentacle tips.
You receive the exact specimen shown in the original photographs. Specimen 417. The photographs were taken under blue aquarium lighting; colours can look different under your own lighting.
Light: moderate without abrupt increases; the trade name 24k is not a lighting requirement. Flow: gentle to moderate and indirect so the tentacles sway freely.
On a stable support with space from neighbours; allow for the expanded polyps.
Sparingly offer small marine food particles when the coral responds and monitor nutrients.
Although sold under Euphyllia, this form is not a glabrescens torch. Judge placement by tissue response and avoid repeatedly moving it.
As a general reef starting point: 24–26 °C, salinity 34–35 PSU, alkalinity 7–8.5 dKH, calcium 410–450 mg/l and magnesium 1,250–1,400 mg/l. Stability matters more than abruptly chasing a number. Avoid complete nutrient depletion and check trends rather than reacting to a single reading.
