The New Zealand demoiselle, Chromis dispilus, is a damselfish of the genus Chromis, found between North Cape and East Cape of the North Island of New Zealand to depths of about 60 metres, off rocky coasts. Its length is between 15 and 20 cm. Males are highly territorial as they defend their nesting area from other males and other species. These aggressive fish defend their eggs laid by their female counterpart. Spawning occurs between the months of December and March. The New Zealand demoiselle's territory and nesting grounds of this fish are usually the largest in a medium population density. Like most territorial fish they tend to spawn more in higher densities of the same species compared to lower densities. Aggression levels tend to be higher amount higher densities of the same species and lower levels in smaller densities. Aggression also tends to be higher during spawning then during egg defending. Elevated plasma levels of androgen testosterone and 11-Ketotesterone are associated with the heighten levels of aggression shown by the males.
The one-spot puller or brown puller, Chromis hypsilepis, is a damselfish of the genus Chromis, found off south-east Australia and between North Cape and East Cape of the North Island of New Zealand to depths of about 60 metres, off rocky coasts. It grows to a length between 15 and 20 centimetres.
Chromis is a genus of fish in the family Pomacentridae. While the term damselfish describes a group of marine fish including more than one genus, most damselfish are in the genus Chromis. These fish are popular aquarium pets due to their small size, tolerance for poor water quality, and bright colors, though their lifespans tend to be shorter than other fish.

The slender tuna, Allothunnus fallai, is a species of tuna, the only species in the genus Allothunnus, found around the world in the southern oceans between latitudes 20° and 50° South, although there are two records of probable vagrants, one in Los Angeles Harbour and the other from the North Pacific subarctic gyre. It has a more elongated body than other species of tuna with which it is symaptric such as the albacore The colour is blue-black on the back with silvery greyish-white sides, however some individuals have a coppery sheen soon after capture. It has a small second dorsal and anal fins resembling a small albacore, but the slender tuna lacks the long sweeping pectoral fins characteristic of albacores. The pectoral fins and pelvic fins are purple on their distal portions and black near their bases. Its length is up to 1 metre (3.3 ft) and it can weigh up to 12 kilograms (26 lb). It occasionally forms schools and its main prey is krill but it is also known to prey on squid and smaller fishes, such as jack mackerel. It is a species of minor commercial importance, taken mainly as bycatch by fisheries for other tuna species. It has rather oily flesh, paler than that of other tuna, but the flesh is palatable when cooked, although it is suitable for canning. The high oil content of the flesh is caused by the oily nature of its diet and varies over the tuna's life, fish which have just fed are high in oil but specimens caught at the end of their migrations will have relatively low oild content. The high concentration of omega-3 polyunsaturated fatty acids in the flesh of this species caused the CSIRO to declare that the slender tuna was Australia's healthiest seafood dish.
