Care

Hoeven's Wrasse is a hardy species that adapts well to life in a home aquarium. They thrive in a well-established tank with plenty of live rock for hiding and foraging. This species is not overly aggressive and can be kept with a variety of other peaceful fish and invertebrates. A varied diet of meaty foods, such as mysis shrimp, brine shrimp, and finely chopped seafood, will help maintain their health and coloration.

Reproduction

In the wild, Ostorhinchus hoevenii are broadcast spawners, releasing eggs and sperm into the water column where fertilization occurs. In the aquarium, breeding is less common, but with a stable environment and proper care, it is possible to observe spawning behavior. The larvae are pelagic and would require specialized care to raise successfully in captivity.

Habitat

Hoeven's Wrasse is found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They are typically associated with coral reefs and lagoons, where they swim at depths ranging from shallow waters to about 30 meters. Their natural habitat includes areas with abundant coral growth and sandy substrates, which provide both food and shelter.
