Green Branching Frogspawn - Euphyllia divisa

Green Branching Frogspawn (Euphyllia divisa)

Green Branching Frogspawn is a popular LPS coral admired for its bright green colouration, fleshy polyps and graceful flowing movement. Its branching skeleton makes it an excellent choice for adding height, motion and natural reef texture to a mixed reef aquarium, while the rounded frogspawn-style tentacle tips create a soft, attractive display under reef lighting.

Common Name:
Green Branching Frogspawn, Branching Frogspawn Coral, Green Frogspawn Coral, Euphyllia Coral

Scientific Name (Latin):
Euphyllia divisa

Coral Type:
LPS Coral

Growth Form:
Branching skeletal growth with large fleshy polyps and rounded, frogspawn-like tentacle tips.

Water Type:
Marine

Origin / Natural Habitat:
Frogspawn corals are found across Indo-Pacific reef habitats, including sheltered reef slopes, lagoons and mixed coral zones where they receive moderate light, stable water quality and gentle to moderate water movement.

Water Parameters:
Temperature: 24–26°C
pH Range: 8.1–8.4
Salinity: SG 1.024–1.026
Alkalinity: 7–10 dKH
Calcium: 400–450 ppm
Magnesium: 1250–1350 ppm
Nitrate: Low but detectable
Phosphate: Low but detectable

Lighting:
MEDIUM
Green Branching Frogspawn is best kept under moderate reef lighting, where its colour and polyp extension can develop well without excessive stress. Avoid placing it directly under intense lighting when first introduced, and acclimate gradually if moving it into a brighter area.

Flow:
LOW TO MEDIUM
Provide gentle to moderate, indirect flow that allows the polyps to sway naturally. Strong direct flow should be avoided, as it can cause the fleshy tissue to retract against the skeleton and may lead to irritation or tissue damage.

Placement:
Place on lower to middle rockwork where the coral can expand fully and remain secure. Allow generous spacing around it, as the fleshy polyps can extend beyond the skeleton and may sting neighbouring corals.

Temperament / Aggression:
Semi-aggressive
Frogspawn corals can sting nearby corals and may extend sweeper tentacles, particularly when competing for space. Keep it away from delicate SPS, soft corals and other LPS corals unless there is enough room to prevent contact.

Feeding:
Photosynthetic, but benefits from feeding
Green Branching Frogspawn receives much of its energy from light through its symbiotic zooxanthellae, but it can benefit from occasional target feeding. Suitable foods include small mysis, fine meaty coral foods, LPS pellets and enriched reef foods. Feed sparingly and avoid oversized foods that may stress the tissue.

Growth Rate:
Moderate
In a stable reef aquarium, Green Branching Frogspawn can gradually develop into a fuller display with healthy polyp extension and steady skeletal growth. Consistent calcium, alkalinity and magnesium levels are important for long-term growth and stability.

Special Requirements or Care Notes:
Maintain stable water parameters and avoid sudden changes in alkalinity, salinity or lighting. Keep the coral away from strong direct flow and allow room for full polyp expansion. Frogspawn corals can be sensitive to tissue damage, brown jelly infections and rough handling, so inspect carefully before introduction and use coral dips where appropriate. Moderate nutrients, stable chemistry and good spacing will help support strong colour and healthy growth.

Suitable for:
Beginner to Intermediate reefkeepers
