The New Zealand demoiselle, also known as Chromis dispilus, is a type of damselfish. These fish live in the waters around the North Island of New Zealand. You can find them from North Cape down to East Cape.
They usually live near rocky coasts. These fish can be found at depths of up to 60 metres (about 200 feet). New Zealand demoiselles are typically between 15 and 20 centimetres (6 to 8 inches) long.
Protecting Their Home and Family
Male New Zealand demoiselles are very protective of their space. They are known to be quite aggressive. They defend their nesting areas from other males of their own kind. They also chase away other fish species.
This strong protective behavior is especially important when they have eggs. The males guard the eggs laid by the female fish. This helps keep the eggs safe until they hatch.
Reproduction and Life Cycle
New Zealand demoiselles lay their eggs between December and March. This time is known as their spawning season. During this period, the males become even more aggressive.
The size of a male's territory depends on how many other demoiselles are around. If there are many fish in an area, their territories might be smaller. However, they tend to lay more eggs when there are more fish of their own kind nearby.
Scientists have found that certain hormones in the males' bodies make them more aggressive. These hormones increase when the males are protecting their eggs or during the spawning season. This helps them defend their nests and ensure their young survive.
