Common name: Rusty Angelfish

General Information

The Rusty Angelfish, scientifically known as Centropyge ferrugata, is a captivating species that has found favor among marine aquarium enthusiasts. With its striking rusty orange coloration and distinctive blue accents along the edges of its fins, this dwarf angelfish is a vibrant addition to any saltwater aquarium. First described in 1972, it has since become a popular choice for hobbyists due to its manageable size and relatively easy care requirements.

While not as commonly seen as some other angelfish species, the Rusty Angelfish is appreciated for its unique appearance and generally peaceful temperament. It is often sought after by aquarists looking to add a splash of color to their reef tanks without the complications associated with larger angelfish species.

Care

The Rusty Angelfish is well-suited for intermediate aquarists. It thrives in a well-established aquarium with plenty of live rock for grazing and hiding. A tank of at least 200 liters is recommended to provide ample space for swimming and territory establishment. This species appreciates a tank environment that mimics its natural coral reef habitat, with stable water parameters and moderate lighting.

Providing a variety of hiding spots and rockwork will help reduce stress and encourage natural behaviors. Although generally reef-safe, caution is advised as some individuals may nip at coral polyps, particularly if not well-fed.

Diet and Feeding

In the wild, the Rusty Angelfish is an omnivore, feeding on a mix of algae, detritus, and small invertebrates. In captivity, its diet should be similarly varied to ensure optimal health. Offer a mix of high-quality marine algae, spirulina, mysis shrimp, and finely chopped seafood. Regular feeding with a variety of foods will help maintain its vibrant coloration and overall health.

Feed the Rusty Angelfish two to three times daily, ensuring that portions are small enough to be consumed within a few minutes. This helps prevent overfeeding and maintains water quality.

Behavior and Compatibility

The Rusty Angelfish is generally peaceful but can be territorial, especially towards other dwarf angelfish. It is best kept singly or in a well-monitored community tank with other peaceful species. Avoid housing it with aggressive or overly territorial tank mates to prevent stress and aggression.

While not toxic, the Rusty Angelfish's territorial nature can lead to skirmishes if not given adequate space or if housed with similar-looking species. Providing ample hiding spots and a well-structured environment can mitigate aggressive behaviors.

Reproduction

Breeding the Rusty Angelfish in captivity is challenging and not commonly achieved. As with many marine species, successful breeding often requires precise control of environmental conditions and a well-established pair. Observing natural spawning behaviors in captivity is rare, and raising fry requires specialized knowledge and equipment.

Health and Common Issues

Rusty Angelfish are generally hardy, but like all marine species, they require stable water conditions and a balanced diet to thrive. Regular monitoring of water quality and prompt treatment of any signs of illness are essential. They can be susceptible to common marine diseases such as ich and velvet, so maintaining optimal water quality and quarantining new additions are recommended practices.

Habitat

Naturally found in the Indo-Pacific region, the Rusty Angelfish inhabits coral-rich areas of lagoons and outer reef slopes. It prefers environments with abundant live rock and coral coverage, where it can find food and shelter. In captivity, replicating these conditions with plenty of live rock and stable water parameters will contribute to the health and well-being of the Rusty Angelfish.
