Overview

Suits keepers with a dedicated predator setup rather than a mixed reef of small fish and shrimp. Bold red, white, and black banding covers the body and broad, fan-like pectoral fins, aiding camouflage among rockwork. Nocturnal and slow-moving, it hides by day and hunts after dark, delivering a venomous sting if mishandled.

Care

A slow, deliberate ambush predator that spends much of the day tucked under ledges or overhangs, becoming more active as light fades. It tolerates a wide range of reef parameters but benefits from dim to moderate lighting and plenty of rockwork with caves to reduce stress. Because it is not a strong swimmer, tankmates that outcompete it for food should be avoided, and water changes should be consistent since it produces a fair bioload from a meaty diet.

Feeding

New arrivals are often started on live saltwater feeder shrimp or small live fish before being weaned onto frozen silversides, krill, or shrimp offered on tongs or tweezers. Feeding two to three times weekly is usually sufficient once the fish is established and feeding reliably. Whole prey items retain more nutritional value than pre-cut pieces, and frozen food should be thawed in tank water rather than at room temperature.

Tank mates

Any fish, shrimp, or crab small enough to fit in its mouth is at risk, including gobies, small wrasses, and ornamental shrimp, so tankmates should be chosen from species too large to be swallowed. It generally ignores corals and sessile invertebrates, making it reef safe with caution rather than reef safe outright. Multiple individuals can sometimes be kept together and have even been observed cooperating during hunts, but this is not guaranteed in captivity and aggression can occur if food is scarce.

Breeding

Pairs spawn at night after a brief rapid ascent together, releasing a buoyant gelatinous egg mass containing thousands of eggs that hatch within about a day and a half. This has occurred in home aquariums on occasion, but raising the pelagic larvae past settlement is difficult and rarely attempted outside of specialized facilities. Sexual differences are subtle and mostly apparent only during courtship, complicating deliberate pairing.

Health

Generally hardy once feeding, but sensitive to copper-based medications, so alternative treatments should be used if disease control is needed. Stress from harsh lighting or lack of hiding spots can suppress appetite, particularly in newly introduced specimens. Careful acclimation and quarantine reduce the risk of injury from handling given the venomous spines.
