Coral Spotted Axillaris Hogfish (Bodianus Axillaris) saltwater aquarium fish portrait

Bodianus axillaris is an Indo-Pacific wrasse that reaches roughly 8 inches in aquariums. Adult males carry a reddish-brown head and forebody that fades to clean white toward the tail, punctuated by conspicuous black marks at the pectoral-fin base and on the soft dorsal and anal fins. Females and juveniles look entirely different: blackish bodies scattered with large white spots. That white spotting is the most reliable way to separate young axillaris from the similarly patterned juveniles of Bodianus mesothorax. In the wild the species occupies clear coral and rocky reefs, ranging across lagoons, seaward slopes, caves, ledges and reef drop-offs.

Adult housing begins at a 50-gallon aquarium, though additional volume is welcome for a fish this active. Layout matters as much as capacity. Combine generous open water for cruising with a rock structure that offers caves, ledges and crevices the fish can use as daytime retreats and nighttime sleeping sites. Expect constant interaction with the bottom: this hogfish works the substrate for prey, flips and shifts loose material, and will direct jets of water into a sandbed to flush out hidden invertebrates. Fine sand may be stirred into suspension and detritus released, so strong mechanical filtration and reliable flow help keep the display clear.

On the reef, Bodianus axillaris concentrates on bottom-dwelling, hard-shelled invertebrates, particularly mollusks and crustaceans. That carnivorous appetite translates directly to the aquarium, where a varied meaty menu keeps color and condition strong. Rotate mysis, fortified brine shrimp, krill, zooplankton, blackworms and marine-based frozen or flake preparations rather than relying on a single item.

Feed two or three times daily. Newly imported specimens are sometimes reluctant to take prepared food during the first days in a new system; live blackworms or adult fortified brine shrimp are usually the most effective triggers for initiating a feeding response. Be aware that the sand-dwelling organisms a mature system supports can be depleted quickly by a foraging hogfish, so do not count on natural productivity to supplement the prepared diet.

This is an active, purposeful swimmer that spends the day patrolling open water and inspecting the substrate. New arrivals often behave shyly and will retreat into rockwork until they settle, which is one reason ample caves and ledges are worth planning for. Juveniles typically live alone beneath ledges or inside caves and frequently pick parasites from other fishes; some adults retain a degree of this cleaning behavior. As the fish matures, semi-aggressive tendencies emerge, particularly toward smaller peaceful species and toward similar-looking wrasses.

Choose tankmates that can hold their own. Larger angelfishes, hawkfishes, groupers and certain triggerfishes make suitable company. Introduction order matters: give a shy hogfish time to establish itself before adding more assertive fishes to the system. In a reef aquarium the species is best treated as reef safe with caution. Corals themselves are not a target, but worms, small crustaceans and small bivalves fall squarely within its natural prey range, and ornamental cleanup crew members may disappear. The habit of blowing water into the sandbed and digging through the substrate adds a second consideration for carefully aquascaped reef displays.

FAQ

Frequently Asked Questions

About the Coral Spotted Axillaris Hogfish

  • What size aquarium does an adult require?
    Plan on a minimum of 50 gallons for an adult, with larger volumes preferred. Prioritize open swimming space paired with a rock structure containing caves and ledges for retreat.
  • Can it be kept in a reef aquarium?
    With caution. Corals are generally left alone, but worms, small crustaceans and small bivalves are potential prey, and its digging and water-blowing behavior can disturb a sandbed.
  • What should I feed it, and how often?
    Offer varied meaty foods such as mysis, fortified brine shrimp, krill, zooplankton, blackworms and marine frozen preparations two or three times daily. If a new fish refuses prepared food, live blackworms or adult fortified brine shrimp often stimulate feeding.
