Getting to Know the Coral Hog
The Coral Hog (Bodianus axillaris), also known as the Axilspot Hogfish, is a colourful, hardy marine fish native to the Indo-Pacific region. Recognised by its deep pink body, yellow fins, and distinct black spot behind each pectoral fin, the Coral Hog brings both beauty and personality to a saltwater aquarium. It’s known for its bold behaviour and curious nature, often exploring every inch of the tank with confidence. While not aggressive by nature, its assertive attitude means it’s best suited for keepers with a bit of experience and a tank with compatible mates.

Tank Requirements
Coral Hogs are active swimmers and grow up to around 20cm (8 inches) in captivity, so they require a spacious tank to thrive. A minimum of 250 litres (around 65 gallons) is recommended, though larger is always better if you’re planning a community setup. They enjoy having room to dart around, as well as rocky areas and caves where they can explore and take shelter.
Live rock is important, not just for the structure and hiding places it offers, but because it supports the natural microfauna Coral Hogs may forage on. A secure lid is also essential—these fish are known to be jumpers, especially when startled.
Water Quality and Parameters
This species is fairly tolerant but thrives best in clean, stable water. Regular maintenance and testing are important to prevent stress and disease:
Temperature: 24°C to 27°C
pH: 8.1 to 8.4
Salinity: 1.023 to 1.025
Flow rate: Moderate to strong
Weekly water changes of 10–15% and strong biological filtration will keep the system healthy. Coral Hogs appreciate good water movement, which helps simulate their natural reef environment and keeps oxygen levels up.
Diet and Feeding
Coral Hogs are carnivores and not particularly fussy when it comes to food. They do best on a varied, protein-rich diet that mimics their natural consumption of crustaceans and other invertebrates:
Mysis shrimp
Brine shrimp
Chopped seafood (squid, shrimp, clam)
High-quality marine pellets and frozen blends
Feeding once or twice daily is typically sufficient. Their hearty appetite makes them one of the easier marine fish to feed, but it’s worth keeping an eye on portion sizes to avoid overfeeding, especially in tanks with slower eaters.
Compatibility and Behaviour
The Coral Hog is semi-aggressive and best housed with other robust, confident species. While it usually gets along fine in a mixed tank, it may harass timid or much smaller fish, particularly new additions. It’s not reef-safe in the strictest sense, as it may pick at small ornamental shrimp or crabs.
Tank mates such as tangs, larger wrasses, clownfish, or dwarf angels usually make good companions. Avoid delicate or passive species that might be bullied or outcompeted at feeding times.
Common Health Issues
Thanks to their hardiness, Coral Hogs are not especially prone to disease, but like all marine species, they can suffer if water quality dips or they are kept under stress. Marine ich, bacterial infections, and parasites can all become problems if proper quarantine procedures aren’t followed.
Make sure new arrivals are quarantined, and always monitor behaviour and appetite. A Coral Hog that stops eating or hides excessively may be signalling a bigger issue.
Final Thoughts
The Coral Hog is a fantastic choice for marine hobbyists looking for a hardy, eye-catching, and interactive fish. With its vivid colours, active nature, and relative ease of care, it’s a rewarding addition to larger, semi-aggressive community tanks. Just be mindful of its tank mates and give it room to roam, and you’ll be treated to a charismatic reef inhabitant that quickly becomes a favourite.
