Bodianus diana is a vibrant and moderately sized wrasse species belonging to the family Labridae. It is characterized by its striking coloration, which can vary significantly between juvenile and adult stages, and also geographically. Adults typically display a reddish-brown to orange body with distinct vertical red bars or blotches, particularly on the posterior half of the body. Juveniles are often more brightly colored with prominent white or yellow spots and black markings. This species is a protogynous hermaphrodite, meaning individuals mature as females and can later change sex to male.
Physical Characteristics
- Body shape
- elongated
- Coloration
- Adults: Reddish-brown to orange body with 3-4 prominent vertical red bars or blotches on the posterior body and caudal peduncle. A large black spot is often present on the dorsal fin and sometimes on the anal fin. Head may have irregular red lines or spots. Juveniles: Often bright yellow or orange with large black spots on the dorsal, anal, and caudal fins, and sometimes on the body. A distinct white or yellow spot is typically present on the upper caudal peduncle.

- Dorsal fin
- Single dorsal fin with 12 spines and 10-11 soft rays. The spinous portion is longer than the soft-rayed portion.
- Tail fin
- Truncate to slightly rounded caudal fin.
- Pectoral fin
- Large and rounded pectoral fins.
- Distinctive fins
- Pelvic fins are relatively long and pointed. Anal fin has 3 spines and 11-12 soft rays.
Identification Tips
Adult Coloration
Look for the reddish-brown to orange body with 3-4 distinct vertical red bars on the rear half of the body and caudal peduncle. A prominent black spot on the dorsal fin is a key identifier.
Juvenile Coloration
Juveniles are bright yellow or orange with large black spots on the fins and a characteristic white or yellow spot on the upper caudal peduncle.
Body Shape
Elongated, somewhat compressed body typical of hogfish species.
Mouth and Teeth
Observe the relatively thick lips and the presence of prominent canine teeth at the front of the jaws, characteristic of Bodianus species.
Habitat
- Water type
- saltwater
- Depth
- Typically found at depths of 6 to 50 meters (20 to 165 feet), but can occur deeper, up to 100 meters (330 feet).
- Environment
- Inhabits coral reefs, rocky reefs, and rubble zones, often near drop-offs or areas with mixed sand and rock. Juveniles are often found in shallower, more protected areas.
- Geographic range
- Indo-Pacific region, from the Red Sea and East Africa eastward to the Line Islands and Tuamotu Archipelago, north to southern Japan, and south to Australia (Great Barrier Reef) and New Caledonia.
Aquarium Information
- Care level: intermediate
- Temperament: semi-aggressive
- Diet: carnivore
- Minimum tank size: 180 gallons (680 liters)
- Temperature: 72-78°F (22-26°C)
- pH level: 8.1-8.4
- Hardness: 8-12 dKH
- Compatibility: Can be kept with other robust, semi-aggressive fish. Not suitable for reef tanks with small invertebrates or docile fish. Only one male per tank, and if multiple females are kept, introduce them simultaneously.
- Special requirements: Requires a well-established aquarium with plenty of live rock for hiding and foraging. A deep sand bed is beneficial as they may burrow at night or when startled. Excellent water quality and strong filtration are essential. Provide a varied diet of meaty foods.
Wild Information
- Conservation status: least concern
- Seasonality: Not subject to specific seasonal fisheries; generally available year-round in its natural range.
- Market price: Moderate to high (for aquarium trade)
- Commercial importance: low
- Taste: Mild, white flesh
- Texture: Flaky, firm
- Cooking methods: Baked, Grilled, Fried, Steamed
- Nutritional value: Good source of lean protein and omega-3 fatty acids.
Key Facts
Sex Changebehavior
Like many wrasses, Bodianus diana is a protogynous hermaphrodite, meaning all individuals are born female and can later change sex to male.
Dietary Habitsbehavior
Red-barred hogfish are opportunistic carnivores, primarily feeding on benthic invertebrates such as crustaceans, mollusks, and echinoderms, which they extract from the substrate using their strong jaws and teeth.
Nocturnal Burrowingbehavior
At night, or when threatened, Bodianus diana will often burrow into the sand or hide among rocks to protect itself from predators.
Color Variationinteresting
The coloration of Bodianus diana can vary significantly with age, geographic location, and even mood, making identification sometimes challenging without familiarity with all life stages.
Safety Information
Handle with care- Safety level: caution
- Venomous: No
- Edibility: edible
- Handling notes: While not venomous, hogfish can deliver a painful bite with their strong jaws and canine teeth if handled carelessly. Exercise caution when handling to avoid bites. Their dorsal fin spines are sharp and can cause punctures.
Similar Species
Axilspot Hogfish
Bodianus axillaris
Bodianus axillaris typically has a more uniform reddish-brown body with a prominent black spot at the base of the pectoral fin (axil), which B. diana lacks. Juveniles of B. axillaris are black with large white spots, differing significantly from B. diana juveniles.
Eclipse Hogfish
Bodianus mesothorax
Bodianus mesothorax has a distinct two-toned body coloration, with the anterior half being dark (often black or dark brown) and the posterior half being lighter (yellow or white), separated by a sharp diagonal line. B. diana lacks this sharp bicolor pattern.
Lyretail Hogfish
Bodianus anthioides
Bodianus anthioides is distinguished by its deeply forked, lyre-shaped caudal fin, which is not present in B. diana (which has a truncate to slightly rounded caudal fin). Coloration also differs, with B. anthioides often having a more mottled pattern.
