Description
Red Finger Gorgonia (Lophogorgia nodulifera)
(Also known as the Red Sea Whip Coral or Red Tree Gorgonian)
Overview
The Red Finger Gorgonia (Lophogorgia nodulifera) is a stunning non-photosynthetic soft coral known for its deep red to orange branches that resemble delicate coral fingers or tree limbs. It adds elegant, flowing movement and vibrant colour to reef aquariums. This species does not contain zooxanthellae, relying entirely on planktonic foods for nourishment. While visually striking, it is challenging to maintain and best suited for experienced reef keepers who can provide frequent feeding and stable, pristine water conditions.
Origin
Native to the Caribbean Sea, Western Atlantic, and Gulf of Mexico, where it inhabits deeper reef slopes and shaded ledges. Found in areas with moderate to strong current, which continuously delivers planktonic food to its polyps.
Feeding
As a non-photosynthetic suspension feeder, the Red Finger Gorgonia requires regular direct feeding with small, planktonic foods. In the aquarium, feed 3–5 times per week (daily if possible) with:
-
Live or concentrated phytoplankton
-
Marine snow or liquid coral foods
-
Rotifers and microzooplankton
-
Fine powdered coral foods (e.g. Reef-Roids, Reef Energy AB+)
Target feeding is most effective — gently direct food toward extended polyps using a pipette or turkey baster during low-flow periods. Consistent feeding is essential for long-term survival.
Lighting
Low to moderate lighting. As a non-photosynthetic coral, Lophogorgia nodulifera does not depend on light for energy. Place in shaded areas or regions of indirect light to prevent algae from overgrowing its tissue.
Water Flow
Moderate to strong, indirect flow. The Red Finger Gorgonia thrives in areas with steady current that keeps its polyps extended and prevents detritus buildup. Avoid laminar or blasting flow that may damage the delicate branches.
Placement
-
Place in the mid to lower sections of the aquarium, ideally in a shaded or overhung area.
-
Secure the base firmly into rockwork or substrate to prevent shifting in flow.
-
Ensure surrounding corals do not come into contact with its branches, as irritation or tissue damage may occur.
Tank Mates
Peaceful and reef safe. Compatible with:
-
Small, non-aggressive reef fish (gobies, blennies, firefish, cardinalfish)
-
Invertebrates such as shrimp, crabs, snails, and sea stars
-
Most corals, provided adequate space is given
Avoid:
-
Large angelfish, butterflyfish, or other species known to pick at coral polyps
-
Aggressive LPS or stinging corals (e.g. Euphyllia, Galaxea) nearby
Aggression
Peaceful. Does not sting or attack other corals but can be damaged by nearby aggressive species or encroaching algae. Ensure good water flow and placement spacing.
Experience Level
Advanced. Requires dedicated feeding, stable water quality, and appropriate flow to remain healthy. Ideal for experienced aquarists familiar with maintaining non-photosynthetic (NPS) coral systems or nutrient-managed reef tanks.
Water Parameters
-
Temperature: 24–26°C (75–79°F)
-
pH: 8.1–8.4
-
Salinity: 1.024–1.026 SG
-
Hardness (dKH): 8–12
-
Calcium: 400–450 ppm
-
Nitrate: <10 ppm
-
Tank Size: Minimum 75 gallons (280L) for stability and feeding consistency
Maintain high water quality, consistent feeding, and strong nutrient export via skimming or refugium.
Reef Compatibility
Reef safe. The Red Finger Gorgonia adds stunning colour and movement to mature reef systems but requires regular feeding and moderate flow to prevent tissue loss. Works well in low-light or NPS reef displays.
