Acropora secale
An Acropora forming low hummocks. Branches reach 20 mm in diameter and 70 mm in length and taper towards the tips; the lower branches are longer, giving the colony a level top. The corallites sit in vertical rows of alternating sizes.
Acropora secale is a branching staghorn coral of the western Indo-Pacific, ranging from the coasts of East Africa, Mozambique, Rodrigues, Aldabra and Chagos east to Singapore, Thailand, Indonesia, Japan, the Philippines, Taiwan and northern and western Australia; the type locality is Sri Lanka. It grows on outer reef flats, reef slopes, reef edges and walls, and SeaLifeBase records a depth range of 3-10 m. Colonies form low hummocks with cylindrical branches up to 20 mm in diameter and 70 mm long that taper towards the tips; the lower branches are longer than the upper ones, giving the colony a level-topped look. The corallites are arranged in vertical rows of alternating sizes, with axial corallites up to 3 mm across and radial corallites opening in long tubular or nose-like mouths. Colour schemes include purple with yellow branch tips, pale brown with blue tips, plain green and plain brown. It is a hermaphrodite that spawns once a year, six days after the full moon. The IUCN lists it as Endangered and it is on CITES Appendix II.

Temperature
24〜27℃
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.
The low, level-topped colony wants light and flow reaching its whole upper surface evenly. LiveAquaria places stock of this species in the strong-flow category.
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.
The yellow or blue branch tips are the main attraction. It is a hermaphrodite that spawns once a year, six days after the full moon. 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 Secale is 24〜27℃. Avoid sudden temperature changes and maintain a stable environment.
Acropora Secale typically reaches Branches up to 20 mm in diameter and 70 mm long as an adult. Size may vary depending on care conditions and individual genetics.
Acropora Secale 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.
