The Redbanded perch (Hypoplectrodes huntii) is a small, demersal marine fish belonging to the family Serranidae, which includes groupers and sea basses. It is characterized by its distinctive reddish-brown banding pattern over a lighter body, a feature that aids in camouflage within its rocky reef habitats. This species is a relatively small predator, primarily feeding on small invertebrates and crustaceans. It is known for its territorial behavior and is often observed solitary or in small groups among rocky crevices and algal beds. While not a major commercial fishery species, it is occasionally caught as bycatch and is of interest to divers and underwater photographers due to its striking coloration.

Identification Tips
Coloration and Banding
Look for the distinct reddish-brown vertical bands on a lighter body. The number and intensity of these bands are key identifiers.
Fin Structure
Observe the continuous dorsal fin with its spiny and soft-rayed portions, and the truncate caudal fin.
Size
This is a relatively small species, rarely exceeding 20 cm in total length.
Habitat
- Water type
- saltwater
- Depth
- Typically found in depths ranging from 5 to 50 meters (16 to 164 feet), though occasionally deeper.
- Environment
- Inhabits rocky reefs, rubble zones, and areas with dense algal growth. Prefers sheltered areas with plenty of crevices and caves for hiding.
- Geographic range
- Endemic to the temperate waters of New Zealand, including the North Island, South Island, and Chatham Islands. Its distribution extends to the Kermadec Islands.

Key Facts
Endemic to New Zealandinteresting
The Redbanded perch is found exclusively in the waters around New Zealand and its associated islands, making it a unique part of the region's marine biodiversity.
Camouflage Masterbehavior
Its distinctive reddish-brown banding provides excellent camouflage against the rocky and algal backgrounds of its reef habitat, allowing it to ambush prey and evade predators.
Small but Mighty Predatorbehavior
Despite its small size, H. huntii is an active predator, playing a role in controlling populations of small invertebrates on the reef.
Safety Information
Handle with care- Safety level: caution
- Venomous: No
- Edibility: edible
- Handling notes: While not venomous, like many serranids, it possesses sharp dorsal fin spines and opercular spines that can inflict painful punctures if handled carelessly. Use caution when handling to avoid injury.

Caprodon longimanus
While also pinkish, the Pink maomao has a more elongated body, lacks the distinct vertical banding of H. huntii, and typically inhabits deeper, offshore waters.

Various
Other species within the genus Hypoplectrodes, such as H. maccullochi (Half-banded perch), may have similar body shapes but differ in the number, width, and completeness of their body bands, as well as their geographic distribution.
