Swiftia exserta
A gorgonian from Florida to the Caribbean with slender, vivid red-orange branches and white to pale yellow polyps. It lacks zooxanthellae, so feeding is mandatory and it suits experienced keepers.
Swiftia exserta is a plexaurid gorgonian of the western Atlantic, from off Florida through the Bahamas to the Gulf of Mexico. A soft gorgonin axis branches finely in a single plane to form a fan. The branch tissue is a vivid red-orange and the white to pale yellow polyps give strong colour contrast, so it is sold as the orange tree gorgonian. Like most gorgonians it is non-photosynthetic and holds no zooxanthellae, so lighting will not sustain it. Phytoplankton and fine zooplankton must be offered several times a day to keep polyps open across the whole colony. That feeding load degrades water quality, so skimming and water changes are essential. Use strong random flow and keep sediment from collecting between branches.

The ideal temperature for the Swiftia (Orange Tree Gorgonian) is 24〜27℃.
Origin
Western Atlantic (off Florida, Bahamas, Gulf of Mexico)
Temperature
24〜27℃
Zooplankton and phytoplankton (feeding is mandatory; it does not photosynthesise)
No zooxanthellae, so lighting is unnecessary; a shaded spot or under an overhang suits it.

Strong random flow. Mounting the fan across the current improves feeding efficiency.
24-27 C and 1.022-1.025 specific gravity. Heavy feeding fouls water, so maintain skimming and water changes.
Feed phytoplankton and fine zooplankton several times daily; polyps that stay closed for days suggest underfeeding.
It needs both heavy feeding and clean water, so it is advanced. Exposed skeleton means tissue recession; review flow and feeding.
Advanced. This is an advanced-level species. It requires specialized equipment and advanced husbandry skills with precise environmental control.
The ideal temperature for Swiftia (Orange Tree Gorgonian) is 24〜27℃. Avoid sudden temperature changes and maintain a stable environment.
Swiftia (Orange Tree Gorgonian) feeds on: Zooplankton and phytoplankton (feeding is mandatory; it does not photosynthesise). Aim for a balanced diet with appropriate feeding frequency.
