Acropora echinata
An Acropora whose flat, bottlebrush-like branches carry thin, neatly arranged branchlets. The branchlet tips are blue or purple against a white or cream ground, and some colonies are entirely blue. It lives on sheltered reefs in clear water.
Acropora echinata was described by James Dwight Dana in 1846. It occurs in Palau, the central Pacific, Southeast Asia, the Indo-Pacific, Australia, the Indian Ocean, the East China Sea and Japan; its range is wide but it is not common. It lives on sheltered tropical shallow reefs in clear water at depths of 8-25 m, and also on sand slopes and lagoon floors. Colonies are built from flat, bottlebrush-like branches with thin, neatly arranged branchlets. The incipient axial and axial corallites are indistinguishable, and the radial corallites are short and tubular, inconspicuous or absent. The branchlet tips are blue or purple against a white or cream ground, and some colonies are entirely blue. In aquaria it reaches 15 cm across. Its resistance to temperature-driven bleaching is very low: in Palau in 1998 every specimen was affected. The IUCN lists it as Endangered and it is on CITES Appendix II.

Mainly nutrition from symbiotic zooxanthellae, supplemented with powdered or liquid coral foods and phytoplankton.
Requires strong light. AlgaeBarn cites successful Acropora keeping at PAR 800 or more. Start newly added colonies under reduced light and raise it over several weeks.
In the wild it lives on sheltered reefs in clear water. The thin branchlets break easily, so avoid a direct blast of flow and use broad movement that still leaves no dead spots.
Water 22-26C, specific gravity 1.023-1.025, KH 8-12, calcium 380-440 ppm, magnesium 1300-1400 ppm. Sudden swings in alkalinity are the most common cause of tissue loss.
Most of its nutrition comes from photosynthesis by its zooxanthellae. Powdered or liquid coral foods and phytoplankton can be offered as a supplement, but stable light and water chemistry matter more than feeding.
Its resistance to temperature-driven bleaching is very low, so temperature stability is the first priority. WoRMS treats the name as an unreplaced junior homonym. Listed on CITES Appendix II.
Advanced. This is an advanced-level species. It requires specialized equipment and advanced husbandry skills with precise environmental control.
The ideal temperature for Acropora Echinata is 24〜27℃. Avoid sudden temperature changes and maintain a stable environment.
Acropora Echinata typically reaches Reaches 15 cm in diameter in aquaria as an adult. Size may vary depending on care conditions and individual genetics.
Acropora Echinata feeds on: Mainly nutrition from symbiotic zooxanthellae, supplemented with powdered or liquid coral foods and phytoplankton.. Aim for a balanced diet with appropriate feeding frequency.
