Cardinalfish General description


Cardinalfish are a large family of saltwater fish made up of over 200 sub-species. Most species are extremely colorful and grow to only a couple of inches in length. They are also an extremely peaceful species of fish and can exist in large groups, making them a popular choice amongst most beginner aquarists. They are also one of the hardier species of saltwater fish able to adapt quickly to life in an aquarium. Cardinalfishes are nocturnal and prefer to spend the daytime hiding in caves and crevices in the aquarium.

Origins


Cardinalfishes originate in the Indian, Pacific and Atlantic Oceans.


Color


Most species of cardinalfish are brightly colored and come in shades of red, yellow, orange, silver, brown and black.


Maintenance and care

Cardinalfishes are extremely peaceful and make excellent additions to most community aquariums. However, due to their small size, they should not be housed with larger predatory species of fish. Although cardinalfish develop complex social hierarchies they are not overly aggressive towards each other, and thrive when kept in large groups in the aquarium. The exception to this is the Banggai cardinalfish.


Cardinalfishes thrive when kept in aquariums with sufficient hiding spaces and their aquariums should be heavily decorated with rocks and coral. They are nocturnal and will retreat into the rockwork and caves in the aquarium during the daytime. They also form intimate relationships with invertebrates like sea urchins which they swim amongst for protection.


Feeding


Cardinalfish thrive when fed on live foods such as shrimp, brine shrimp and other small crustaceans. They can also be trained to accept most varieties of processed frozen foods.

Breeding


Cardinalfishes are one of the easier species of saltwater fish to breed in captivity. They spawn in pairs and are mouthbrooders. Once the eggs are laid and fertilized, the male will carry them in his mouth for about a week until they hatch. In the wild, the fry intermingle with plankton for a couple of months while they develop.


Aquarium varieties


Five Lined Cardinalfishes, Flame Cardinalfishes, Longspine Cardinalfishes, Spotted Cardinalfishes, Yellowstriped Cardinalfishes, etc.
