Rusty Angelfish in the ideal aquarium

Rusty Angelfish - Centropyge ferrugata

Setting up the best tank for the Rusty Angelfish requires a well filtered minimum of 70 gallon/265 litre tank. As shy species, the tank should be decorated with large amounts of live rocks that provide them with lots of hiding places and facilitate the growth of algae upon which they will graze.

These species are not good reef dwellers as they will often nip at the precious corals, sessile invertebrates and clam mantles.

These species tend to be overly aggressive to other Dwarf Angelfish species, and as such should be kept as the only Dwarf Angelfish species in the tank.

However, they are safe with similar species such as Anthias and Clownfish, but they should be introduced last to an already established aquarium.

Rusty Angelfish feeding

Rusty Angelfish are omnivores and their food should be based on a variety of meaty and vegetable matters. Spirulina, fresh or frozen mysis shrimp, other high quality prepared foods and a lot of marine algae.

Rusty Angelfish breeding

Just as with most Dwarf Angelfish species, the Rusty Angelfish are born female with the most dominant fish changing to male. They lack visible distinguishing factors between the male and female which makes it difficult to breed them in captivity.
