Care
One-spot Foxfaces are hardy and adaptable, making them suitable for both novice and experienced aquarists. They require a tank with plenty of swimming space and live rock for grazing. It's important to handle them with care, as they have venomous dorsal spines that can inflict painful stings. A varied diet that includes algae and marine-based foods will help maintain their health and vibrant coloration.
Reproduction
In the wild, Siganus unimaculatus forms pairs during the breeding season. They are broadcast spawners, releasing eggs and sperm into the water column where fertilization occurs. In the aquarium, breeding is rare, but providing a stress-free environment with optimal water conditions may encourage spawning behavior.
Symbiosis
While not known for specific symbiotic relationships like clownfish with anemones, the One-spot Foxface does play a role in the reef ecosystem by grazing on algae, which helps prevent overgrowth and maintain a balance in the coral reef environment.
Habitat
The natural habitat of the One-spot Foxface includes coral reefs and lagoons in the Indo-Pacific region. They are often found in shallow waters where they have access to their primary food source, algae. Their range extends from the eastern Indian Ocean to the western Pacific Ocean, including the Great Barrier Reef and the islands of Micronesia.
