Orange Photosynthetic Gorgonian

Muricca elongata (often sold simply as an “Elongate Gorgonian” or “Brown Muricca Gorgonian”) is a hardy, photosynthetic gorgonian known for slender, elongated branches with a rough, lightly spiny texture. Its polyps are usually tan, cream, or light brown, giving it a natural, wild-reef look. This species is more forgiving than many fan-shaped gorgonians and thrives in mixed reefs when flow and cleanliness are right.

Lighting

Moderate light is ideal, typically 80 to 150 PAR. Muricca elongata holds its natural coloration well under these levels. Higher light is tolerated but can cause lightening at the branch tips if not acclimated. Too little light reduces polyp extension and slows growth.

Flow

Strong, turbulent flow is essential. Elongata has a textured surface that catches detritus easily, so crossfire flow from multiple directions keeps the branches clean and the polyps open. If the flow is too weak, algae films will develop quickly and the coral will withdraw polyps.

Placement

Mid to high in the aquascape is usually best. This species prefers open water where branches can sway without rubbing on rocks. It grows upward and outward in thin, elongated rods rather than dense fans, so give it vertical room.

Water parameters

Standard soft-coral-friendly reef conditions.

Calcium 400 to 420.
Alkalinity 8 to 9.
Magnesium 1300 to 1350.
Nitrate 5 to 20.
Phosphate 0.05 to 0.15.

Muricca elongata does well in nutrient-positive tanks and dislikes ultra-low-nutrient systems. Stable salinity is especially important because gorgonian tissue is sensitive to osmotic swings.

Feeding

Although photosynthetic, it benefits from occasional small-particle foods such as phytoplankton, rotifers, or fine coral blends. Polyp extension is usually strong during the day and makes feeding effective. Heavy feeding isn’t necessary.

Growth behavior

Moderate growth speed. The colony forms long, slender, slightly curved branches with a lightly spiny surface. Polyps extend densely along the branches, giving a soft, fuzzy appearance. Fragging is simple: cut a branch segment, glue the base, and it attaches readily.

Sensitivities

Low flow is the primary enemy. Algae film and detritus will irritate polyps and eventually smother tissue. Overly intense lighting without acclimation can cause tip bleaching. Avoid direct contact with aggressive LPS or corals with strong sweepers.

Compatibility

Very peaceful. It coexists well with zoanthids, leathers, LPS, and even SPS as long as nothing stings it. Its long branch structure provides great movement and serves as a natural perch for gobies and small fish.
