Care guide

Overview

Deep violet corallites edged in a bright neon-green rim give this Favites its layered, low-domed look as it slowly encrusts its plug and adjacent rockwork. Moderate light and gentle indirect flow suit it best, with ample clearance from neighbors for its nighttime sweeper tentacles. Stable alkalinity, calcium, and magnesium keep growth steady over time.

Care

Favites tolerates a broad range of reef conditions and is a reasonable choice for hobbyists moving beyond soft corals into LPS. It does best under low to medium light and gentle, indirect flow that keeps its tissue clean without folding it against the skeleton. Stable alkalinity, calcium, and magnesium support steady skeletal growth, and sudden parameter swings should be avoided since shifted tissue can recede along the shared corallite walls.

Placement & acclimation

Acclimate gradually to light by starting in a lower or shaded position and moving it up over several weeks, since sudden bright exposure can bleach the tissue. Mount frags securely on rockwork or a frag plug with reef-safe epoxy or glue, leaving generous open space around the colony for both growth and sweeper tentacle activity. It can also be placed directly on the sand bed in a stable position where it will grow into a mounded form.

Feeding

Most of its nutrition comes from photosynthetic zooxanthellae, but it extends feeder tentacles at night to capture meaty foods drifting past. Offering small pieces of mysis, chopped seafood, or LPS pellets once or twice a week can improve coloration and growth over time. New colonies should settle in for a couple of weeks before target feeding begins.

Neighbors

This coral is capable of stinging with sweeper tentacles that extend mostly at night, so at least 4 inches of clearance from neighboring corals is recommended. It is not well suited to close-packed frag gardens with acans, zoanthids, or other LPS, since contact can damage both colonies over time. Favia, brain corals, and chalice corals in particular should be kept at a safe distance given their similar growth habits and potential for confusion during placement.

Fragging

Colonies can be fragged by cutting or cracking the skeleton between corallites with a band saw or coral cutters, ideally leaving at least one intact corallite per fragment. Cut edges should be handled carefully and placed in low flow until tissue recovers and covers the exposed skeleton. Fragging is best done on healthy, well-extended colonies to reduce stress and infection risk.

Pests & problems

Bleached or pale patches usually indicate excess light exposure, since this genus prefers subdued lighting compared to many other LPS. Exposed white skeleton near the tissue margin can signal flow that is too strong or direct, causing localized recession. Brown jelly infections and tissue necrosis can occur after physical damage or shipping stress, so newly acquired frags should be monitored closely during acclimation.
