Common name: Bengal Sergeant

General Information

The Bengal Sergeant, scientifically known as Abudefduf bengalensis, is a striking species often found in the reefkeeping hobby. This fish is known for its bold vertical black stripes on a silver body, making it a visually appealing addition to any marine aquarium. It is a member of the Pomacentridae family, which includes damselfishes and clownfishes.

In the hobby, the Bengal Sergeant is appreciated for its hardiness and adaptability, making it a good choice for both novice and experienced aquarists. Its role in the ecosystem as a cleaner fish and its contribution to the biodiversity of reef tanks are notable.

Care

The Bengal Sergeant is relatively easy to care for, thriving in well-maintained aquariums with plenty of swimming space. It prefers environments with live rock and coral structures that mimic its natural habitat, providing hiding spots and territories. These fish are adaptable to a range of conditions but prefer stable water parameters to flourish.

Diet and Feeding

Bengal Sergeants are omnivorous, feeding on a diet that includes algae, plankton, and small invertebrates. In captivity, they should be offered a varied diet consisting of high-quality marine flakes, pellets, and frozen foods like brine shrimp and mysis shrimp. Feeding them twice a day in small portions helps maintain their health and vibrant colors.

Behavior and Compatibility

Bengal Sergeants are semi-aggressive, especially in smaller tanks or when establishing territory. They are best kept in larger aquariums where they can coexist with a variety of tank mates. Providing ample space and hiding spots can help mitigate aggressive behaviors. They are generally compatible with other semi-aggressive species but can bully smaller, more timid fish.

Reproduction

Breeding Bengal Sergeants in captivity can be challenging. They exhibit typical damselfish breeding behaviors, where the male prepares a nesting site and guards the eggs until they hatch. Raising the fry requires careful attention to water quality and feeding with appropriate foods like rotifers and baby brine shrimp.

Health and Common Issues

Bengal Sergeants are hardy fish but can be susceptible to common marine diseases such as ich and marine velvet. Maintaining good water quality, a balanced diet, and a stress-free environment are crucial to preventing these issues. Quarantining new additions and regular health checks can further reduce the risk of disease.

Habitat

Native to the Indian Ocean, the Bengal Sergeant is commonly found in coral reefs and rocky coastal areas. They thrive in environments with plenty of hiding spots and moderate water flow, replicating the conditions of their natural habitats.
