AI illustration Overview
The frogspawn coral rounds out the Euphyllia trio - a dense cluster of tentacles tipped with grape- or spawn-like bunched ends that give it its name, flowing in the current like the hammer but bushier. Hardy, forgiving for an LPS, and a great first Euphyllia. (Euphyllia divisa and the branching Euphyllia paradivisa.)
Origin & Habitat
Indo-Pacific reefs, on slopes in moderate light and gentle-to-moderate flow.
Appearance
Branching stony base topped with masses of tentacles ending in clustered, bubbly tips, usually green or tan with glowing highlights.
Placement & Temperament
Like the hammer, it has stinging sweeper tentacles - keep 15 cm from non-Euphyllia corals. Generally peaceful with hammers and other frogspawn; keep torches apart.
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 100-175 PAR) and gentle to moderate flow.
Feeding
Photosynthetic; benefits from occasional small meaty target feeding.
Health & Growth
One of the more forgiving Euphyllia and a good beginner LPS. Same brown-jelly caution as the hammer - act fast if a head starts to rot.
Pros & Cons
Pros
- Bushy, beautiful movement
- Most forgiving Euphyllia
- Grows into a large branching colony
Cons
- Stinging sweepers - needs space
- Brown jelly risk
- Dislikes strong direct flow

Frogspawn Coral - frequently asked questions
Frogspawn vs hammer vs torch - which is easiest?
Frogspawn and hammer are the more forgiving, beginner-friendly Euphyllia; torch is the touchier, more aggressive one. All need space from non-Euphyllia corals.
Can frogspawn and hammer touch?
They usually tolerate each other and other frogspawn, but it is safest to leave a small gap. Keep both well clear of torches and non-Euphyllia corals.
