Cespitularia spp.
A xeniid soft coral that branches from a thick stalk, with polyps bearing eight pinnate tentacles clustered at the branch tips. Specimens with a blue, pale blue or greenish metallic sheen are prized in the aquarium trade.
Cespitularia is a genus of octocoral soft corals in the family Xeniidae, order Malacalcyonacea, found on shallow reefs across the Indo-West Pacific. Colonies branch from a thick stalk with polyps bearing eight pinnate tentacles clustered at the branch tips. Specimens with a blue, pale blue or greenish metallic sheen are prized by aquarists, but the genus is easily confused with Xenia and Heteroxenia in the same family and trade names alone are unreliable. Note that WoRMS treats the genus as a taxon inquirendum, meaning its validity is unsettled. It is zooxanthellate and draws most of its nutrition from photosynthesis. Within the family it is regarded as relatively sensitive to changes in water quality, and colonies are known to shrink shortly after introduction and then melt away. As a soft coral with no stony skeleton it is not covered by the CITES coral listings.

Origin
Shallow reefs of the Indo-West Pacific, including Indonesia and north-eastern Australia

Mainly nutrition from its zooxanthellae, with micro-plankton or foods for filter-feeding invertebrates as a supplement.

LiveAquaria lists xeniids as high-light corals, so provide medium to strong light; in low light the metallic sheen fades.
Xeniids prefer medium to strong flow. Give it enough current to move the branches and mount it on mid-level rockwork, with clearance from neighbouring corals.
Water 24-26C, specific gravity 1.023-1.025 (salinity 33-35 ppt), pH 8.1-8.4, KH 8-12. Iodine and trace elements are recommended. It reacts badly to sudden changes in water chemistry.
Most of its nutrition comes from photosynthesis. Micro-plankton or foods for filter-feeding invertebrates offered about once a week are beneficial.
Colonies are known to shrink and melt shortly after introduction, so acclimate slowly. The genus is taxonomically unsettled, so do not rely on trade names for identification. Having no stony skeleton, it is not covered by the CITES coral listings.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The ideal temperature for Cespitularia is 24〜26℃. Avoid sudden temperature changes and maintain a stable environment.
Cespitularia feeds on: Mainly nutrition from its zooxanthellae, with micro-plankton or foods for filter-feeding invertebrates as a supplement.. Aim for a balanced diet with appropriate feeding frequency.
