In nature this omnivore grazes a broad menu that includes nudibranchs, the tentacles of sessile worms, gastropods, bivalves, coral polyps, assorted benthic invertebrates, and both macroalgae and benthic microalgae. That mixed feeding strategy translates directly to captive husbandry: the diet should be varied and weighted toward small meaty items, with a vegetable component included regularly. Suitable offerings include mysis shrimp, enriched brine shrimp, finely chopped clam, mussel, cockle, crustacean flesh, and squid, plus formulated frozen preparations. Round the menu out with algae-based flakes, spirulina foods, dried marine algae sheets, or quality pellets.

Feed small portions several times each day rather than one large meal, which better matches its natural pattern of near-constant grazing. Newly imported wild fish sometimes refuse food at first; clam or mussel presented on the half-shell, or soft food pressed into the crevices of a bare coral skeleton, often triggers the first bites. Juveniles tend to settle onto prepared foods more readily than large adults, and captive-bred specimens arrive already accustomed to pellets and other aquarium diets, which removes much of the guesswork during acclimation.

On the reef this species is largely nocturnal and is typically seen in pairs or small groups, yet it adapts readily to daytime aquarium lighting and feeding schedules. Aquarium accounts describe it as peaceful toward unrelated fishes, and it makes a calm, visually striking centerpiece for a large community of similarly sized tankmates. It is usually best kept singly unless the system is exceptionally large; if conspecifics are attempted, introduce same-sized individuals at the same time and supply plenty of visual barriers so each fish can break line of sight. Guidance on mixing it with other butterflyfishes is inconsistent, with some accounts reporting significant hostility and others noting that mixed groups can work when added simultaneously, so proceed cautiously and be prepared to separate. Avoid very small or exceedingly docile tankmates, along with any fish that cannot shrug off occasional chasing.

This species is not reef safe. It readily consumes coral polyps and is considered unsafe around most ornamental corals and desirable invertebrates. Its documented natural diet of hard corals, sessile worms, gastropods, and bivalves also puts feather dusters, ornamental snails, and clams at risk. It does eat pest Aiptasia and Majano anemones, which some aquarists find appealing, but that appetite does not extend selectively; prized anemones and other sessile invertebrates are equally likely targets. Reserve it for fish-only displays or systems decorated with live rock rather than corals.
