Nephthea Leather Coral Care Guide – Care, Feeding & Lighting Tips

Introduction

Nephthea corals (Nephthea species) are soft leather corals admired for their tree-like appearance and graceful movement. Their branching polyps add visual interest and motion to reef tanks, making them a popular choice for aquarists seeking dynamic soft corals.

Scientific Name & Identification

Belonging to the family Nephtheidae, Nephthea corals are recognized by their branching fingered polyps and flexible, tree-like structure. Polyps are small, extend primarily during the day, and retract when stressed. Their coloration ranges from green and tan to brown, often with subtle fluorescent highlights under actinic lighting.

Natural Habitat

Nephthea corals are native to the Indo-Pacific, often found on shallow reef slopes, flats, and lagoons with moderate water movement. Their natural environment guides their aquarium placement and care requirements.

Aquarium Care & Setup

To maintain healthy Nephthea corals:

• Temperature: 74–80°F (23–27°C)

• pH: 8.1–8.4

• Salinity: 1.024–1.026

• Flow: Moderate, gentle turbulence encourages polyp extension

• Lighting: Moderate to high; sufficient light enhances coloration

• Placement: Rockwork or sandbed, with space for branches to move and expand

Feeding

While primarily photosynthetic, Nephthea corals benefit from occasional feedings of phytoplankton or fine powdered foods. Target feeding can encourage growth and promote vibrant colors.

Growth and Behavior

Nephthea grow into branching, tree-like colonies. Their polyps sway in water currents, creating dynamic movement in the aquarium. They are semi-aggressive and should be spaced away from sensitive SPS corals to prevent chemical interference.

Tankmates

Nephthea corals are compatible with most reef-safe fish and other soft or hardy LPS corals. Ideal tankmates include tangs, clownfish, gobies, and cleaner shrimp. Avoid housing them too close to sensitive SPS corals due to chemical defenses.

Conclusion

Nephthea corals are hardy, visually dynamic soft corals that bring movement and texture to any reef aquarium. Their adaptability, moderate growth, and ease of care make them ideal for beginner and intermediate reef keepers. With proper flow, lighting, and occasional feeding, Nephthea will thrive and enhance the beauty of a reef display.
