Care guide

Overview

Branches spread in an open, loosely packed pattern rather than a tight bush, carrying blue-green polyps and rounded green tips. As the colony fills out, outer growth can starve the interior of flow, so periodic pruning and strong turbulent water movement are needed. Keep several inches from other corals to avoid sweeper contact.

Care

This finely branched SPS forms dense, bushy colonies and colors up best under stable, moderate-to-high light with strong, turbulent flow reaching the inner branches. It is more sensitive to swings in alkalinity, temperature and nutrients than many other SPS, often responding to instability with tissue recession or branch tip bleaching. Because branches are thin and brittle, handle frags by the base or plug rather than the tips, and avoid placing new tanks under a year old before adding this species.

Placement & acclimation

Mount frags securely on rock or a plug in the upper-middle to high zone of the tank where strong, turbulent flow can reach between the branches. Acclimate new colonies to light gradually over one to three weeks, starting at lower intensity, since sudden increases can cause bleaching. Position with several inches of open space from other corals to avoid stinging contact and self-shading as the colony fills in.

Feeding

Most nutrition comes from photosynthesis via zooxanthellae, but growth and coloration benefit from occasional feeding of very fine particulate foods such as rotifers, copepod nauplii, phytoplankton or powdered coral foods. Because the polyps are small with limited prey-capture ability, larger frozen foods are not usable; keep feedings to fine particle sizes a few times a week. In a well-stocked, well-fed reef tank with good ambient plankton and dissolved organics, supplemental feeding is often unnecessary.

Neighbors

Give this coral several inches of clearance from neighbors, as its branches carry short stinging sweeper tentacles and can release chemical defenses to compete for space. It can hold its own against peaceful corals but may lose ground to more aggressive species with longer sweepers such as euphyllia or galaxea. As colonies enlarge, outer branches can shade or block flow to the interior, so periodic pruning or fragging helps maintain even growth and coloration.

Fragging

Fragging is done by cutting or snapping branches with bone shears and mounting the pieces on plugs or rubble; healed cuts regenerate quickly given stable conditions. Colonies can also reproduce via polyp bail-out under stress, where detached polyps drift and occasionally settle to form new colonies, though this is uncommon in captivity for this species.

Pests & problems

Watch for Seriatopora-eating nudibranchs and small crustacean pests that can hide deep within the branch clusters and cause tissue loss. Rapid changes in light, flow or water chemistry are the most common causes of paling, bleaching, or rapid/slow tissue necrosis (RTN/STN) in this species. Under very low nutrient conditions colonies can pale, while excess nutrients tend to cause browning, so stable, moderate nutrient levels are preferred.
