The Zebra (Diplodus hottentotus) is a species of marine ray-finned fish belonging to the family Sparidae, the seabreams and porgies. It is characterized by its distinctive vertical banding pattern, which gives it its common name. This species is a demersal fish, typically found in coastal waters over rocky reefs and sandy bottoms.
Physical Characteristics
- Body shape
- compressed
- Coloration
- Silvery-grey body with 7-9 prominent dark vertical bands that extend from the dorsal fin to below the lateral line. The caudal fin is often dark-edged. Juveniles typically have more pronounced banding.
- Scale type
- ctenoid
- Mouth position
- terminal
- Distinctive features
- 7-9 dark vertical bands on the body, Small, terminal mouth with incisor-like teeth at the front and molars at the sides, Large eyes, Deep body
- Dorsal fin
- Single dorsal fin with 11-12 spines and 12-13 soft rays.
- Tail fin
- Moderately forked caudal fin.
- Pectoral fin
- Long and pointed pectoral fins.
- Distinctive fins
- Anal fin with 3 spines and 11-12 soft rays.
Identification Tips
Vertical Bands
The most distinguishing feature is the 7-9 dark vertical bands across its silvery body. These bands are usually quite distinct.
Body Shape
Its deep, compressed body is characteristic of the Sparidae family.
Mouth and Teeth
Observe the small, terminal mouth with incisor-like teeth at the front, adapted for grazing and nipping.
Habitat
- Water type
- saltwater
- Depth
- Typically found from the surface down to about 80 meters (260 feet), but most commonly in shallower waters (5-30 meters).
- Environment
- Prefers rocky reefs, kelp beds, and areas with mixed sand and rubble. Juveniles may be found in estuaries and sheltered bays.
- Geographic range
- Endemic to the temperate waters of the southeastern Atlantic Ocean, primarily along the coast of South Africa, from Namibia to KwaZulu-Natal.
Aquarium Information

- Temperament: semi-aggressive
- Diet: omnivore
- Minimum tank size: 200 gallons
- Temperature: 20-26°C (68-79°F)
- pH level: 8.1-8.4

- Compatibility: Can be kept with other robust, similarly sized marine fish. May be aggressive towards smaller or more docile species, especially conspecifics if not introduced carefully or in a sufficiently large tank.
- Special requirements: Requires a well-established marine aquarium with plenty of live rock for hiding and grazing. Good filtration and stable water parameters are crucial. A varied diet including both meaty foods and vegetable matter is essential.
Wild Information
- Conservation status: least concern
- Seasonality: Available year-round, but fishing efforts may vary seasonally based on local regulations and fish abundance.
- Market price: Moderate
- Commercial importance: medium
- Taste: Mild, white flesh

Key Facts
Dietary Flexibilitybehavior
Diplodus hottentotus is an opportunistic omnivore, feeding on a wide range of benthic invertebrates, small crustaceans, mollusks, and algae. This dietary flexibility allows it to thrive in various coastal habitats.
Social Behaviorbehavior
Zebra fish are often observed in small schools or aggregations, particularly around rocky reefs, where they forage together.
Reproductive Strategybehavior
Like many sparids, Diplodus hottentotus is a protogynous hermaphrodite, meaning individuals mature first as females and later can change sex to male. This strategy is common in species where larger males have a reproductive advantage.
Ecological Rolebehavior
As a mid-level consumer, the Zebra plays an important role in coastal ecosystems, grazing on algae and preying on invertebrates, thus influencing the structure of reef communities.
Safety Information
Safe- Safety level: safe
- Venomous: No
- Edibility: edible
- Handling notes: No specific handling precautions beyond standard fish handling. Its dorsal and anal fin spines can be sharp, so care should be taken to avoid punctures.
Similar Species
White Steenbras
Lithognathus lithognathus
The White Steenbras has a more elongated body, a silvery-white coloration without prominent vertical bands, and a more pointed snout. It also lacks the distinct dark caudal fin edge of the Zebra.
Santer
Cheimerius nufar
The Santer has a reddish-pink to silvery-pink coloration, lacks the vertical bands, and has a more robust, less compressed body shape. Its dorsal fin spines are also typically longer.
Blacktail
Diplodus capensis
While also a Diplodus species, the Blacktail typically has fewer and less distinct vertical bands (often only a dark blotch on the caudal peduncle and a dark spot at the pectoral fin base), and a more uniformly silvery body. Its caudal fin is distinctly black-edged.
