🐸 Frogspawn Coral Description

• Scientific Name: Euphyllia divisa (sometimes confused with Euphyllia paradivisa, which has thinner branches)

• Common Names: Frogspawn coral, Octopus coral

• Family: Euphylliidae

• Appearance: Large fleshy polyps that resemble a cluster of frog eggs or octopus tentacles—hence the name

• Color Variants: Green, pink, brown, gold, or cream with tips that may be neon green, purple, or white

• Growth Form: Branching or wall-forming structures depending on species; branching forms are more common in the hobby

🌊 Movement & Behavior

• Tentacles: Wavy, flowing tentacles that extend during the day and retract somewhat at night

• Aggression: Semi-aggressive; has sweeper tentacles that can sting nearby corals

🔬 Biological Notes

• Photosynthetic: Contains symbiotic zooxanthellae that provide nutrition through photosynthesis

• Supplemental Feeding: Accepts small meaty foods such as mysis shrimp or coral foods

🧪 Ideal Water Parameters

• Temperature: 76°F–80°F (24.5°C–27°C)

• Salinity: 1.024–1.026 specific gravity

• pH: 8.1–8.4

• Alkalinity: 8–11 dKH

• Calcium: 400–450 ppm

• Magnesium: 1250–1350 ppm

• Nitrates: <10 ppm (some tolerance up to 20 ppm)

• Phosphates: <0.05 ppm

🔆 Lighting & Flow

• Lighting: Moderate (PAR 80–150)

  • Compatible with LED, T5, or hybrid setups

  • Avoid overly intense lighting; may bleach or retract

• Water Flow: Moderate

  • Just enough to gently sway the tentacles—too much flow can cause them to retract or tear

📍 Placement Tips

• Tank Zone: Middle to lower regions of the tank

• Space Needed: At least 3–5 inches from other corals due to sweeper tentacles

• Compatibility: Best with other Euphyllia (like torch or hammer) if enough space is provided

🍤 Feeding

• Feeding Type: Optional but beneficial

• Foods Accepted: Mysis shrimp, brine shrimp, finely chopped seafood, coral foods like Reef Roids

• Feeding Frequency: 1–2 times per week to encourage growth

🧼 Care Tips

• Acclimation: Drip acclimate to reduce stress

• Stability: Requires stable parameters; vulnerable to sudden changes

• Fragging: Easily fragged if branching—cut at the base between polyps

• Pests to Watch: Brown jelly disease, flatworms, or nudibranchs

✅ Summary: Is Frogspawn Coral Beginner-Friendly?

Yes! It’s hardy, visually stunning, and relatively easy to care for, making it an excellent choice for hobbyists looking to explore LPS corals.
