Dendronephthya spp.
A non-photosynthetic soft coral in vivid red, pink or orange. Sclerites show through the tissue and give the branches a spiky look. It has no zooxanthellae and needs a near constant supply of fine foods such as phytoplankton.
Dendronephthya is a genus of octocoral soft corals in the family Nephtheidae, order Malacalcyonacea, with more than 250 described species. Colonies are vivid red, pink or orange, and the sclerites visible through the tissue give the branches a spiky appearance. The genus is non-photosynthetic, hosting no zooxanthellae, so its nutrition depends entirely on suspended matter captured from the water. It attaches on current-swept reef slopes and under overhangs and inflates or deflates the colony by taking in water. It is sometimes offered for aquariums but is notoriously difficult to keep, requiring a near constant supply of small foods such as phytoplankton. Where feeding is inadequate the colony shrinks over weeks to months and the branches waste away. As a soft coral with no stony skeleton it is not covered by the CITES coral listings.

It has no zooxanthellae, so light is not needed; in the wild it attaches in dim places such as under overhangs. Under bright lighting algae settle on it and weaken the colony.
It grows where current is strong, so give it vigorous randomised flow and a position where suspended food keeps reaching the branches. Mounting it upside down under an overhang is closest to its natural posture.
Water 24-26C, specific gravity 1.023-1.025 (salinity 33-35 ppt), pH 8.1-8.4, KH 8-12. Heavy feeding drives nutrients up, so run generous water changes and mechanical filtration.
Success depends on feeding. AlgaeBarn notes that non-photosynthetic systems need large amounts of varied food across a range of particle sizes and recommends combinations that include live phytoplankton and bacterioplankton. Feeding several times a day, or dosing automatically, is the practical approach.
It is very demanding and long-term success is rarely reported; under-fed colonies shrink over weeks to months. Having no stony skeleton, it is not covered by the CITES coral listings.
Advanced. This is an advanced-level species. It requires specialized equipment and advanced husbandry skills with precise environmental control.
The ideal temperature for Dendronephthya (Carnation Coral) is 24〜26℃. Avoid sudden temperature changes and maintain a stable environment.
Dendronephthya (Carnation Coral) feeds on: Azooxanthellate and filter-feeding, needing a near constant supply of fine foods, phytoplankton above all.. Aim for a balanced diet with appropriate feeding frequency.
