Coral Spotted Axillaris Hogfish (Bodianus Axillaris) saltwater aquarium fish

Overview:

The Coral Spotted Axillaris Hogfish is a hardy, highly active marine fish best suited to a mature reef or predator-style aquarium with plenty of open swimming room and secure rockwork. It does best in a tank of at least 125 gallons, with stable water quality, strong filtration, and moderate to high oxygenation. Provide a sandy bottom with caves and crevices for retreat, but leave open space for cruising. This species is intelligent and bold, and can become stressed in cramped systems or in tanks with timid tankmates. Like other hogfishes, it may rearrange small décor and investigate the substrate, so all structures should be firmly anchored. Stable salinity, low ammonia and nitrite, and consistently low nitrate are important for long-term health.

Diet and Feeding:

This species is carnivorous and should be fed a varied, protein-rich marine diet. Offer high-quality marine pellets or marine carnivore pellets as a staple, supplemented with frozen mysis shrimp, chopped shrimp, krill, clam, squid, and other meaty foods. Occasional vitamin-enriched foods help support color and immune function. Feed small portions 2 to 3 times daily rather than one large meal, since hogfishes are energetic and benefit from frequent feeding. Use only what is consumed quickly to avoid water fouling. A varied diet is especially important because this fish can become selective if fed only one food type. Soaking foods in marine vitamins or HUFA supplements is beneficial, especially during acclimation or recovery.

Compatibility:

The Coral Spotted Axillaris Hogfish is generally compatible with robust, similarly sized marine fish that can hold their own. Good tankmates include tangs, larger angelfish, triggers, puffers, wrasses, groupers, and other semi-aggressive species. It is not ideal with very small fish, shrimp, crabs, snails, or other decorative invertebrates, as it may harass or eat them. Avoid housing it with highly timid species, slow feeders, or fish with long flowing fins, since hogfishes can be assertive and sometimes nippy. Territorial conflicts are more likely in undersized aquariums, so adding the hogfish after more peaceful tankmates are established often improves success. When keeping multiple bold species, ensure the tank is large enough to break up sightlines and reduce aggression.

Health and Quarantine:

Quarantine all new individuals for at least 2 to 4 weeks in a separate system before introduction. This allows observation for marine ich, velvet, bacterial infections, and feeding issues. Provide calm conditions, stable temperature, and frequent small feedings during quarantine. The species is generally durable, but it can develop stress-related illness if exposed to poor water quality or abrupt changes in salinity and temperature. Watch for rapid breathing, loss of appetite, flashing, frayed fins, or unusual hiding. Preventive care should focus on pristine water, a varied diet, and careful acclimation. Regular testing and prompt correction of water chemistry problems are essential, since this fish thrives on stability.

The Coral Spotted Axillaris Hogfish is an active, open-water swimmer that also appreciates a complex aquarium with ample rockwork and hiding places to retreat into when startled. It is generally semi-aggressive and territorial, especially toward conspecifics and similarly shaped wrasses, so it is best kept singly unless in a very large system. A minimum tank size of 125 gallons is recommended, with a layout that includes strong visual barriers and plenty of swimming room to reduce stress and aggression. With suitable tank mates, it can coexist well with robust, non-fragile reef-safe species, though smaller ornamental crustaceans and other invertebrates may be at risk. This species is carnivorous, feeding primarily on small crustaceans, worms, mollusks, and other meaty prey items it actively hunts. In captivity, it does best on a varied diet of frozen and prepared marine foods offered several times per week to support its high activity level.

FAQ

Frequently Asked Questions

About the Coral Spotted Axillaris Hogfish

  • How big does a Coral Spotted Axillaris Hogfish really get, and what tank size does it need long-term?
    It can reach about 10–12 inches as an adult, with a thick-bodied, active swimming profile. A juvenile may seem manageable in a 75–90 gallon tank, but a true long-term home should be at least 125 gallons with plenty of open swimming room and strong rockwork.
  • Is the Coral Spotted Axillaris Hogfish safe with cleaner shrimp, snails, and small crabs?
    Usually no. This hogfish is a crustacean hunter and will often eat cleaner shrimp, peppermints, ornamental crabs, small hermits, and sometimes even large snails if it can pry them loose. It’s better treated as fish-only-safe, not reef-safe in the “invertebrate-friendly” sense.
  • What should I feed a Coral Spotted Axillaris Hogfish to keep its color and body condition strong?
    Feed a varied meaty diet: chopped shrimp, mysis, krill, squid, clam, marine flesh, and quality carnivore pellets. It does best with multiple small feedings per day when young, then 1–2 substantial feedings as an adult. Rich, varied foods help maintain the bright coral spotting and prevent it from thinning out.
  • Can a Coral Spotted Axillaris Hogfish be kept with other semi-aggressive fish, or will it bully them?
    It is usually assertive but not wildly destructive. It pairs best with similarly sized, sturdy tankmates like tangs, larger angels, triggers with caution, groupers, or other robust wrasses. Avoid very timid fish, tiny gobies, and anything small enough to be swallowed. It may become bossy as it matures, especially in cramped tanks.
  • Does the Coral Spotted Axillaris Hogfish need sand to sleep in like many wrasses?
    No, it does not typically rely on burying in sand the way many wrasses do. It prefers rock ledges, caves, and secure sleeping crevices. Provide plenty of hiding spots and a calm night environment, because it likes to wedge itself into sheltered areas after dark.
