Black Indian Trigger

Description

The Black Indian Trigger, scientifically known as Melichthys indicus, can reach a maximum size of around 12 inches (30 cm). It has a distinctive appearance with a laterally compressed body and a slender, pointed snout. The fish is predominantly black in colour, with a yellow dots and dashes pattern.

Behaviour

The Black Indian Trigger exhibits an intriguing mix of puppy-like character and intelligence. It possesses a mesmerizing swimming motion thanks to the shape and undulation of their fins. These fish gracefully navigate through the water. These fish are known for their curious and inquisitive nature, often interacting with their environment and showing a range of captivating behaviours.

Taxonomy

The Black Indian Trigger belongs to the family Balistidae, which includes various triggerfish species. Its closest relatives within the genus Melichthys include the Titan Triggerfish (Melichthys niger) and the Redtail Triggerfish (Melichthys vidua). The genus name “Melichthys” is derived from the Greek words “melas” meaning black and “ichthys” meaning fish, highlighting the fish’s prominent black colouration.

Natural Habitat

The Black Indian Trigger inhabits coral reefs and rocky areas in its natural habitat. It can be found in the Indo-Pacific region, including the Maldives, the Red Sea, and the coastlines of India and Sri Lanka. These areas provide the fish with an abundance of hiding places, crevices, and coral formations that it seeks for protection and foraging.

Keeping Black Indian Trigger Healthy:

To ensure the health and well-being of the Black Indian Trigger, it is crucial to maintain appropriate tank conditions. This species requires a tank with a minimum capacity of 75 gallons (284 litres) to accommodate its active swimming habits. Water temperature should range from 75°F to 82°F (24°C to 28°C), with a specific gravity of 1.020 to 1.025. Regular water changes and efficient filtration are essential for maintaining optimal water quality.

Special Requirements and Feeding

The Black Indian Trigger has specific dietary requirements and should be offered a varied diet consisting of meaty foods. This can include shrimp, fish, squid, and other protein-rich options. Providing a balanced diet is vital for the fish’s overall health and vitality.

How Many Should I Keep?

It is recommended to keep a single Black Indian Trigger in the aquarium due to its territorial nature and potential aggression towards conspecifics or similar species.

Lighting Preference

The Black Indian Trigger does not have any specific lighting preferences. However, providing a well-lit aquarium with appropriate spectrum lighting can enhance the overall visual appeal of the tank.

Suitable Tank Mates

When selecting tank mates for the Black Indian Trigger, it is essential to choose larger and more robust species. Smaller, peaceful fish may become targets of aggression. It is generally not advisable to keep the Black Indian Trigger with other triggerfish or similar aggressive species.

Reproduction in the Wild

During the reproduction process, the Black Indian Trigger performs a unique courtship behaviour known as the “wiggle dance.” This dance involves rapid shaking movements of its body, which are believed to attract potential mates. The fish swims in a zigzag pattern while vigorously shaking its body, creating a visual display to signal its readiness to reproduce.

Breeding Melichthys indicus:

1. 1. Set Up:

   To encourage breeding, a spacious aquarium with suitable hiding places and crevices should be provided. The water temperature should be maintained between 77°F and 82°F (25°C to 28°C).

   2. Courtship/Spawning:

   Triggerfish are known to form monogamous pairs during the breeding season. The courtship behaviour involves the male actively pursuing the female, displaying vibrant colours and performing courtship rituals such as the wiggle dance. Once the female accepts the male’s advances, they engage in spawning.

   3. Rearing:

   Triggerfish lay adhesive eggs on a flat surface, typically within a crevice or on the substrate. The male guards and aerates the eggs, while the female may remain nearby. After hatching, the fry should be provided with appropriate nutrition, such as small live or frozen foods.

Sexual Dimorphism

The Black Indian Trigger does not exhibit significant sexual dimorphism, making it challenging to visually differentiate between males and females based on physical characteristics alone.

Distribution

The Black Indian Trigger, Melichthys indicus, is naturally found in the Indo-Pacific region. Its distribution extends from the coastlines of East Africa to the Maldives, the Red Sea, and the coastal areas of India and Sri Lanka. While some individuals may be available as captive-bred specimens, the original wild fish come from their natural range in the Indo-Pacific.

Summary

The Black Indian Trigger, scientifically known as Melichthys indicus, is a captivating fish with its distinct appearance and mesmerizing swimming motion. Known for their puppy-like character and intelligence, these fish add a unique charm to the aquarium. While their care level may require some attention, they can thrive in a well-maintained tank with appropriate tank mates and a balanced diet. Reproduction in the wild involves the fascinating wiggle dance courtship behaviour. Breeding the species in captivity can be challenging, but providing the right setup and conditions may increase the chances of success. The Black Indian Trigger is a remarkable fish that brings beauty and personality to any aquarium setting.
