General Description
The Two-spot basslet, scientifically known as Pseudanthias bimaculatus, is a member of the Sea Bass family (Serranidae) found in the Indo-West Pacific region, including East Africa, the Maldives, and Indonesia. This delicate species can grow up to 14.0cm in size and requires a minimum tank size of 400 liters. Known for its shyness and docile nature, the Two-spot basslet acclimatizes best when introduced to aquarium conditions at a young age.
Aquarium Suitability
Due to its delicate nature, the Two-spot basslet demands experience, preparation, and extra care from aquarists. It can be aggressive if not provided with adequate space, making it essential to house it with non-aggressive tankmates. Additionally, this species is known to jump out of open aquariums, necessitating careful attention to tank security.
Care and Hardiness
The Two-spot basslet is considered delicate and requires a varied diet consisting of small crustaceans like krill and mysis, as well as zooplankton such as Cyclops and pods. It is crucial to provide hiding places within the aquarium, such as live rocks, to allow the fish to feel secure. Acclimating the Two-spot basslet to aquarium conditions should be gradual, with dimmed lighting initially to mimic its natural environment.
Reef Suitability
Known for being reef safe, the Two-spot basslet is a suitable addition to reef aquariums. It thrives in a reef setting and is compatible with various coral species, adding vibrance and activity to the underwater ecosystem without posing a threat.
Aquarium Setup
To create an optimal environment for the Two-spot basslet, aquarists should provide a well-established tank with ample hiding spots and subdued lighting. Maintaining stable water conditions with a temperature range of 22.2-25.6°C, pH of 8.1-8.4, and specific gravity between 1.020-1.025 is crucial for the health and well-being of this species.
Behaviour
This species is known for its shy and docile temperament, preferring to hide initially while acclimating to its surroundings. When introduced to a suitable environment with compatible tankmates, the Two-spot basslet can display peaceful behavior, provided its space requirements are met.
Feeding and Diet
The Two-spot basslet requires frequent feeding several times a day, especially during the acclimation period. Initially, offering foods like Cyclops and Artemia is recommended, with the fish gradually adapting to consuming fish flakes. A varied diet rich in small crustaceans and zooplankton ensures the proper nutrition and overall health of this species.
Dimorphism
The Two-spot basslet is hermaphroditic, capable of changing from a female to a male as needed. This gender flexibility allows for reproductive adaptability within the species, contributing to its survival and breeding success.
Habitat and Distribution
In the wild, the Two-spot basslet inhabits the East Indian Ocean, West Indian Ocean, Australia, Indonesia, and the Central/West Pacific regions. Its natural habitat includes coral reefs and rocky crevices, where it seeks shelter and forages for food among the vibrant marine ecosystem.
