Eclipse Hogfish (Bodianus Mesothorax) saltwater aquarium fish

Overview:

Eclipse Hogfish is best kept in a spacious, mature marine aquarium with excellent water quality and strong oxygenation. Despite the “hogfish” name, this is an active, bold, and highly mobile fish that needs plenty of open swimming room plus rockwork for shelter and nighttime retreat. A tight-fitting lid is essential, as startled individuals may jump. Stable reef parameters are important: salinity 1.023–1.026, temperature 74–78°F, pH 8.1–8.4, and low ammonia/nitrite with consistently low nitrate. Good filtration, strong circulation, and regular water changes help prevent stress. Provide a sand bed if possible, since hogfish often forage close to the bottom and may rest there during periods of inactivity. This species does best in established systems where natural hiding places and a varied environment reduce stress and support natural behavior.

Diet and Feeding:

Eclipse Hogfish is a carnivorous, protein-hungry feeder that should receive a varied diet to stay healthy and maintain coloration. Offer a mix of marine-origin foods such as mysis shrimp, chopped krill, clam, squid, shrimp, and high-quality carnivore marine pellets. Frozen foods enriched with vitamins and marine fatty acids are especially useful for long-term conditioning. Feed small portions 2–3 times daily, only as much as the fish consumes promptly. Because hogfish are active feeders and can become greedy, avoid overfeeding, which can degrade water quality and contribute to obesity. Soaking foods in vitamin supplements and occasional marine omega-3 additives can support immune function and recovery during acclimation or after transport.

Compatibility:

Eclipse Hogfish is generally peaceful to semi-aggressive, but its bold personality means tankmate selection matters. It usually does well with similarly sized, confident fish such as tangs, larger wrasses, angelfish, rabbitfish, and robust clownfish. Avoid housing it with very small, delicate species that may be intimidated or outcompeted for food. Tiny ornamental crustaceans, shrimp, and crabs may be at risk, since hogfish are opportunistic predators and may investigate invertebrates as prey. Very aggressive tankmates can also stress the fish and cause hiding, poor feeding, or injury. In community settings, introduce it after calmer species are established and monitor closely during the first weeks. It is best kept singly unless the aquarium is large enough to manage territorial behavior.

Health and Quarantine:

Quarantine is strongly recommended for at least 3–4 weeks before introduction to the display tank. Observe for external parasites, bacterial lesions, rapid breathing, flashing, loss of appetite, or excessive hiding. Like many marine fish, Eclipse Hogfish can be susceptible to marine ich, velvet, and stress-related bacterial infections if acclimation is rushed. Maintain pristine water, provide varied food, and reduce handling to support immunity. In quarantine, offer frequent small meals and watch body condition closely, since the species can lose weight quickly if stressed. If disease appears, prompt diagnosis and treatment in a separate hospital system are essential. Preventive care relies on stable salinity, low stress, and consistent nutrition.

Eclipse Hogfish are active, constantly cruising wrasses that use open swimming space but also benefit from caves, overhangs, and other hiding spots for security. They are generally bold and semi-aggressive, with strong territorial tendencies, and are especially intolerant of conspecifics or similarly shaped, competitive tankmates. A minimum tank size of 100 gallons is recommended, with a layout that includes substantial rockwork and visual barriers to break lines of sight and reduce chasing behavior. In mixed systems, they usually coexist best with robust, non-passive fish, but they are not fully reef-safe because they may prey on small crustaceans, snails, and other invertebrates. They are carnivorous, feeding primarily on small benthic prey, including crustaceans, worms, and other meaty foods, and in captivity should be offered a varied diet of frozen and prepared seafood-based fare.

FAQ

Frequently Asked Questions

About the Eclipse Hogfish

  • Is the Eclipse Hogfish actually reef safe, or will it eat my clean-up crew and ornamental shrimp?
    Not truly reef safe. The Eclipse Hogfish is a predatory wrasse that will usually ignore corals, but it commonly targets small crustaceans like ornamental shrimp, tiny crabs, hermits, and other invertebrates once it matures. It is best kept in a fish-only-with-live-rock setup or a very carefully chosen reef with no small mobile inverts.
  • How big does an Eclipse Hogfish get, and how much tank space does it really need long term?
    It grows into a substantial wrasse, commonly reaching around 10–12 inches as an adult. Because it is an active swimmer and a robust predator, a 180-gallon tank is a much better long-term minimum than the smaller tank sizes often suggested for juveniles. It needs plenty of open swimming room plus secure rockwork.
  • My juvenile Eclipse Hogfish is bright and peaceful now—will its behavior change as it matures?
    Yes, very often. Juveniles are usually more adaptable and relatively calm, but adults become bolder, more assertive, and sometimes aggressive toward smaller or similarly shaped fish. They may also become more confident at feeding and more likely to bully timid tankmates if the tank is cramped or overstocked.
  • What should I feed an Eclipse Hogfish to keep its colors strong and prevent it from becoming picky?
    Feed a varied carnivorous diet: chopped seafood, mysis shrimp, krill, silversides in moderation, clam, squid, and high-quality marine carnivore pellets. It does best with multiple small feedings per day when young, then 1–2 richer meals daily as an adult. A varied diet helps maintain the yellow, red, and blue facial coloration typical of the species.
  • Can Eclipse Hogfish be kept with other wrasses or aggressive tankmates, and are there any compatibility issues to watch for?
    They can be kept with semi-aggressive or robust tankmates, but caution is needed with other wrasses, especially similar-bodied species, because territorial disputes can happen. They usually do best with larger, confident fish such as tangs, triggers, angels, or big rabbitfish, provided the system is large enough. Avoid tiny, timid fish that can be harassed or eaten, and make sure the tank has a tight lid because wrasses are excellent jumpers.
