Pseudodax moluccanus

Datasheet

General Description: The Chiseltooth wrasse, scientifically known as Pseudodax moluccanus, belongs to the Labridae family and can be found in the Indo-Pacific region, ranging from the Red Sea to South Africa and extending to various islands in the Pacific. These fish are known for their attractive appearance and their role in battling unwanted invertebrates in reef aquariums. Wrasses like the Chiseltooth wrasse feed on a wide range of food, from zooplankton to large crustaceans and sea urchins.

Aquarium Suitability: The Chiseltooth wrasse is considered suitable for aquariums, but with care. They require a very large aquarium when fully grown and are known to jump out of open tanks, so a secure lid is essential. Additionally, they need a deep sandy substrate for burrowing and plenty of hiding spots amongst live rocks. These fish can be sensitive during transportation and acclimatization, needing frequent feeding and a varied diet.

Care and Hardiness: This species is considered average in terms of hardiness. They are mostly peaceful but can exhibit aggression towards similar species. Chiseltooth wrasses are hermaphroditic, with the ability to change gender from female to male, and can coexist as a pair if introduced simultaneously.

Reef Suitability: The Chiseltooth wrasse is always reef safe and can be a valuable addition to reef aquariums. They help in removing parasites from other fish but may not have a significant impact on large parasite outbreaks. It is crucial not to stress the fish by constant cleaning, especially if they are weakened by other factors.

Aquarium Setup: Setting up an aquarium for the Chiseltooth wrasse involves providing a spacious tank with ample swimming space, a deep sandy substrate for burrowing, live rocks for hiding, and a secure lid to prevent jumping out. Maintaining stable water conditions with a pH range of 8.1-8.4, a specific gravity of 1.020-1.025, and a temperature between 22.2-25.6°C is essential for their well-being.

Behaviour: These wrasses are known to be active swimmers and enjoy swimming freely in the aquarium. They should be provided with enough space to roam and explore. However, they can be sensitive to changes and may exhibit stress if not provided with appropriate hiding spots and a varied diet.

Feeding and Diet: Chiseltooth wrasses primarily feed on parasites, larger crustaceans, small crustaceans, and other invertebrates. They require a varied diet to thrive and should be fed multiple times a day, especially when newly introduced into the aquarium. Ensuring they can find natural food in the tank can reduce the frequency of feedings.

Dimorphism and Captive Reproduction: This species can change gender from female to male, adapting as needed within the environment. Whilst they are hermaphroditic, captive reproduction and breeding behaviors are not extensively documented.

Habitat and Distribution: The Chiseltooth wrasse inhabits a wide range, from the Red Sea to South Africa, and various islands in the Pacific such as the Society, Marquesan, and Tuamoto islands. They prefer sandy substrates for burrowing and rocky areas for shelter, reflecting their natural habitat in the wild.
