Common name: Ornate Cowfish

General Information

The Ornate Cowfish, scientifically known as Aracana ornata, is a fascinating species found in the waters of southern Australia. Recognized for its striking, ornate patterns and boxy body shape, this fish is a member of the boxfish family. Its unique appearance, characterized by vibrant colors and intricate markings, makes it a captivating addition to public aquariums, though it is less common in home setups due to its specific care requirements.

In the wild, the Ornate Cowfish plays a role in the local marine ecosystem, contributing to the biodiversity of reef environments. While not commonly kept by hobbyists, it is appreciated for its educational value and the aesthetic appeal it brings to exhibits focused on marine diversity.

Care

Keeping an Ornate Cowfish requires a well-maintained marine aquarium with stable water conditions. They prefer tanks with ample swimming space and plenty of live rock for grazing and exploration. The tank should be large enough to accommodate their potential size and provide a peaceful environment, as they can be stressed by aggressive tank mates.

Due to their unique body structure, Ornate Cowfish are not the fastest swimmers and require a tank with moderate water flow. They benefit from a varied diet that includes marine algae, small crustaceans, and specially formulated pellets to ensure they receive all necessary nutrients.

Diet and Feeding

Ornate Cowfish are omnivorous, feeding on a mix of plant material and small invertebrates in the wild. In captivity, their diet should reflect this variety. Offering a combination of high-quality marine pellets, algae sheets, and occasional live or frozen foods like mysis shrimp will help maintain their health and vibrant coloration.

Feed them once or twice a day, ensuring that the food offered is appropriate for their size and mouth structure. Avoid overfeeding, as it can lead to water quality issues and health problems.

Behavior and Compatibility

Ornate Cowfish are generally peaceful but can be territorial towards other boxfish or similarly shaped species. They are best kept in a species-specific tank or with other non-aggressive fish that do not compete for the same food sources.

These fish have a unique defense mechanism: when stressed or threatened, they can release a toxin that is harmful to other fish. Therefore, it's crucial to maintain a stress-free environment and avoid housing them with overly aggressive species.

Health and Common Issues

Ornate Cowfish can live for several years in captivity if provided with proper care. Their unique body shape requires careful attention to water quality and diet to prevent health issues. Regular monitoring of water parameters and ensuring a balanced diet are essential for their well-being.

They are susceptible to skin infections and parasitic diseases, so maintaining a clean environment and observing them for any signs of illness is important. Quarantining new additions to the tank can help prevent the spread of diseases.

Habitat

Native to the coastal waters of southern Australia, the Ornate Cowfish inhabits rocky reefs and seagrass beds. They prefer shallow, sheltered waters where there is plenty of cover and food availability. Replicating these conditions in captivity can help ensure their health and longevity.
