Why does my Gold Center Frogspawn’s “gold” fade under strong lights, and how can I bring it back?

Fimbriaphyllia paradivisa with gold centers can wash out under high PAR and heavy white spectrum. Aim for moderate PAR (80–150) with a blue-leaning spectrum. Ramp intensity slowly, and maintain stable nutrients (NO3 ~5–15 ppm, PO4 ~0.03–0.1). Trace balance (especially iron and iodine within safe ranges) and consistent alkalinity help. Given time, pigments often deepen again.

My branching heads are receding from the base—how do I stop polyp bailout or brown jelly from spreading?

Increase random flow around the skeleton, siphon decaying tissue immediately, and perform an antiseptic coral dip. If a head shows rapid tissue loss, cut it above healthy skeleton to isolate. Improve oxygenation, reduce organics with fresh carbon, and correct swings in alkalinity, temperature, or salinity—the usual triggers for bailout. Maintain stable parameters until recovery.

Can this coral coexist with torches and hammers, or will they sting each other?

F. paradivisa has long nocturnal sweepers and can be stung by torch corals, which are more aggressive. Keep 6–8 inches clearance from torches and other euphylliids; avoid direct contact even between related species to prevent chemical and physical warfare. Run carbon, ensure good export, and provide crossflow to dilute allelochemicals. Watch for extended sweepers at night and adjust spacing.

What’s the safest way to propagate a Gold Center Frogspawn without losing color or heads?

Only frag true branches, cutting through bare skeleton well below the polyp. Use clean bone cutters or a diamond saw, then iodine-based dip and moderate, turbulent flow for healing. Maintain stable Ca/Alk/Mg and moderate light to avoid color shock. Avoid cutting “wall-like” segments; branching forms heal quickly, while wall sections often suffer recession. Feed lightly during recovery.

Gold Center Frogspawn Coral

Overview

Gold Center Frogspawn Coral features branching heads with gold centers and bulbous tentacle tips. Fimbriaphyllia paradivisa is a branching large-polyp stony coral that prefers moderate light and gentle to moderate water flow. It is photosynthetic through symbiotic algae but benefits from occasional small meaty foods to support growth and color. Provide space from other corals due to stinging sweepers, and avoid strong flow that collapses the polyps.

Care & Placement

Gold Center Frogspawn Coral (Fimbriaphyllia paradivisa) thrives with stable, moderate conditions. Provide moderate light (PAR ~75–150); start low and increase over 1–2 weeks to avoid bleaching. Aim for gentle, indirect flow that keeps polyps swaying without blasting the tissue; this limits detritus buildup and reduces risk of brown jelly. Feed 1–2 times weekly with small meaty foods (mysis, enriched brine) or fine coral foods; target feed lightly to avoid fouling water. Maintain: temperature 76–80°F, salinity 1.025–1.026, pH 8.1–8.4, alkalinity 8–9.5 dKH, calcium 400–450 ppm, magnesium 1250–1350 ppm, nitrate 2–10 ppm, phosphate 0.02–0.08 ppm. Test alk/Ca/Mg weekly, use a refractometer for salinity, and keep changes gradual—this species is sensitive to swings, especially in alkalinity.Place mid to lower in the tank on stable rock with room to grow. Allow 6–8 inches of clearance from other corals; sweepers can extend several inches at night and sting neighbors. Usually tolerant of same-species groupings but can conflict with other LPS and torches. Avoid nipping fish (angels, butterflies); occasional clownfish hosting is possible but can be irritating if persistent. Acclimate with a 30–45 minute drip and dip for pests. For light acclimation, use screens or start in a shaded area. Watch for tissue recession (often too much light/flow or too little nutrient), and address brown jelly by siphoning, iodine dipping, and removing affected heads. Regular, small water changes and steady parameters are key to long-term health.
