(U2) Gorgonian - WYSIWYG

Gorgonian Corals are unique soft corals with a branching, tree-like appearance that brings dramatic height and flow to reef aquariums. Found in a wide variety of colors, including purple, red, yellow, and tan, these corals sway gracefully in the current, adding natural movement to tanks. Some species are photosynthetic and relatively easy to care for, while others are non-photosynthetic and require regular feeding, making them better suited for advanced aquarists.

Description:

Common Names: Gorgonian Coral, Sea Fan, Sea Whip

Scientific Name: Various species (e.g., Pseudopterogorgia, Muricea, Subergorgia)

Family: Gorgoniidae and related families

Temperament: Peaceful

Difficulty: Easy to Difficult (depends on whether species is photosynthetic or non-photosynthetic)

Note: Photosynthetic gorgonians are more beginner-friendly, while non-photosynthetic varieties require frequent target feeding and pristine water conditions.

Native Habitat & Distribution:

Gorgonians are found worldwide, but are especially abundant in the Caribbean and Indo-Pacific. They thrive in reef slopes, lagoons, and areas with strong water movement, where their branching structures can filter nutrients from the water.

Aquarium Care & Setup:

Temperature: 72–80°F (22–27°C)

pH: 8.1–8.4

Salinity: 1.024–1.026

Lighting: Moderate to high for photosynthetic species; low to moderate for non-photosynthetic species (since they don’t rely on light)

Flow: Strong, turbulent flow helps prevent detritus buildup and supports healthy polyp extension

Placement: Upright on rockwork or rubble with space for branches to sway freely

Care Tips & Feeding:

• Feeding: Photosynthetic gorgonians rely on light but may benefit from occasional phytoplankton; non-photosynthetic species require frequent target feeding of phytoplankton, marine snow, or other fine particulate foods

• Growth Pattern: Branching, tree-like colonies that form fans, whips, or bushy structures

• Tankmates: Compatible with peaceful reef fish and invertebrates; avoid species that nip at polyps (e.g., angelfish, butterflyfish)

• Behavior: Delicate tissue can be damaged by algae growth—strong flow is essential to keep surfaces clear

Are Gorgonian Corals easy to keep?

Photosynthetic species are fairly easy, while non-photosynthetic gorgonians are more challenging and require regular feeding.

What lighting do Gorgonian Corals need?

Photosynthetic gorgonians need moderate to high light; non-photosynthetic species prefer lower light since they do not rely on photosynthesis.

Do Gorgonian Corals need feeding?

Yes. Photosynthetic species only need occasional feeding, but non-photosynthetic gorgonians must be fed phytoplankton or similar foods multiple times per week.

Where should I place Gorgonian Corals in my tank?

In strong, turbulent flow areas where their branches can sway freely and avoid algae buildup.

How fast do Gorgonian Corals grow?

Growth varies by species; photosynthetic types grow faster, while non-photosynthetic species grow more slowly.

Are Gorgonian Corals aggressive?

No, they are peaceful corals, but they require space for their branches and should not be shaded by other corals.
