Care guide

Overview

Growth stays compact and densely branching, with pink, green and purple tones mingled across the same colony rather than a single solid hue. It tolerates a broad range of light and flow, though brighter conditions sharpen the color mix. Stable calcium, alkalinity and magnesium are essential, as swings can trigger tissue loss on the branch tips.

Care

This is one of the hardier small-polyp stony corals available in the trade, tolerating a wider swing in parameters than demanding genera like Acropora. It comes from shallow, wave-battered reef flats, so it wants strong, alternating water movement and moderate to high light rather than gentle, laminar flow. Keep calcium, alkalinity and magnesium stable and avoid sudden shifts, since rapid tissue necrosis can set in quickly if chemistry swings too far. New frags should be started at lower PAR and moved up gradually over a couple of weeks to prevent bleaching.

Placement & acclimation

Acclimate new colonies to lighting gradually over two to three weeks, starting around 200-250 PAR before moving to a brighter spot. Mount frags securely on rock with reef epoxy or cyanoacrylate gel on the upper to mid rockwork where flow and light are strongest, and leave several inches of open space around the base since colonies broaden considerably as they mature.

Feeding

Most of its energy comes from zooxanthellae, so direct feeding is not required in a well-lit system with fed fish. Occasional target feeding with fine zooplankton, phytoplankton or powdered coral foods can improve polyp extension and coloration. Feed in moderate flow so particles disperse across the branches rather than settling in one spot.

Neighbors

It lacks sweeper tentacles and stinging power, making it a safe neighbor for most other corals, fish, and reef invertebrates. Still, leave a few inches of clearance from adjacent colonies since its branches thicken and expand with growth and can eventually crowd out slower neighbors through simple contact. Peaceful reef fish, shrimp, and snails all coexist with it without issue.

Fragging

Fragging is straightforward: cut branch tips with a bandsaw, coral cutters, or shears and mount the cut fragments on plugs or rubble until they encrust and begin new growth. Cut in flowing water to reduce tissue stress and let fresh cuts rest in low-moderate light for the first days to heal before returning them to full flow and light.

Pests & problems

Pale or washed-out coloration usually signals either too much light too soon or a nutrient imbalance, while browning can indicate excess nutrients. Tissue recession along the branch tips is the main danger sign and often follows a sudden swing in alkalinity, calcium, or temperature. Inspect new frags for skeleton exposed at the base or torn tissue before adding them to a system, as damaged tissue is an entry point for infection.
