Raja Ampat Creature Feature Solider Fish

Meridian Adventure Dive bring you the monthly Raja Ampat Creature Feature series: Soldier Fish

The blotcheye soldierfish, scientifically known as Myripristis murdjan, is a striking species of fish found in the tropical waters of the Indo-Pacific region. With its vibrant colours and distinctive markings, this fish is a sight to behold and plays a significant role in the ecosystem of coral reefs where it resides.

Blotcheye soldierfish are easily identifiable by their bright red-orange bodies adorned with dark blotches, giving them their name. These fish typically grow to lengths of around 15 to 20 centimetres, although some specimens may exceed this size. They have a slender, elongated body with a slightly flattened shape, allowing them to navigate the intricate coral reef habitats easily.

One of the most striking features of the blotcheye soldierfish is its large eyes, which are proportionally bigger than its body. This adaptation helps them to see well in low-light conditions, as they are primarily nocturnal hunters.

Blotcheye soldierfish are commonly found in shallow reef environments throughout the Raja Ampat Regency. They inhabit coral reefs, rocky outcrops, and other submerged structures, often congregating in large numbers around crevices and overhangs during the day. These fish prefer areas with moderate to strong water currents, which help to supply them with a steady flow of oxygen-rich water.

As nocturnal predators, blotcheye soldierfish are most active at night, venturing out of their hiding spots to hunt for small crustaceans, molluscs, and other small fish. Their large eyes and keen senses allow them to detect prey in dimly lit environments.

During the day, these fish seek shelter within the reef structure, using crevices and caves to avoid potential predators such as larger fish and reef sharks. Their schooling behaviour offers them safety in numbers, as they can quickly dart into the reef’s safety when threatened.

Blotcheye soldierfish are oviparous, meaning they reproduce by laying eggs. During the breeding season, which varies depending on the location, male soldierfish will engage in courtship displays to attract females. Once a suitable mate is found, the female will release her eggs, fertilised by the male, into the water.

The fertilised eggs are buoyant and drift with the currents until they hatch into larvae. These larvae undergo a pelagic stage, drifting in the open ocean before settling in shallow reef habitats as juveniles. As they mature, blotcheye soldierfish develop their vibrant colours and markings, reaching sexual maturity at around two to three years of age.

The blotcheye soldierfish is a visually stunning species essential to coral reef ecosystems. With its remarkable adaptations, behaviours, and role within its environment, this fish is a testament to the incredible diversity in marine habitats.
