Care
Zebrasoma rostratum requires a spacious tank to accommodate its active swimming habits and potential growth up to 20 centimeters in length. A diet rich in marine algae and vegetable matter is crucial for their health, and they will also accept a variety of prepared foods. It's important to maintain high water quality and stable parameters to keep these fish thriving.
Due to their grazing nature, providing ample live rock with natural algae growth will help satisfy their dietary needs and promote natural foraging behavior. They can be sensitive to rapid changes in water conditions, so acclimation should be done carefully and slowly.
Reproduction
In the wild, Black Longnose Tangs are broadcast spawners, releasing eggs and sperm into the water column where fertilization occurs externally. In the home aquarium, breeding is rare and challenging, but not impossible for experienced aquarists with large, well-established systems.
Habitat
The natural habitat of Zebrasoma rostratum includes the coral reefs of the Central and Western Pacific Ocean. They are typically found at depths ranging from 10 to 60 meters, where they swim in clear waters above the reef, grazing on algae.
Their geographical distribution spans from the Great Barrier Reef to the islands of Oceania, including Tahiti and the Hawaiian Islands. In the wild, they are often observed singly or in small groups.
