The Timor Cardinalfish, scientifically known as Apogonichthyoides timorensis, is a captivating species of fish belonging to the cardinalfish family. This fish is distinguished by its vibrant colors and intriguing behavior, making it a fascinating subject of study for marine biologists and aquarists alike.

Description & Characteristics

The Apogonichthyoides timorensis is a relatively small fish, reaching a maximum size of 9.0 cm. Its body is slender and elongated, with a compressed profile. Its dorsal fin is composed of two distinct parts: a short, spiny section followed by a longer, soft-rayed section. The anal fin is also relatively long and is positioned opposite the soft-rayed portion of the dorsal fin. This cardinalfish showcases a distinctive color pattern, often displaying a mix of reds, oranges, and yellows, with contrasting dark markings.

Habitat and Occurrence

The Apogonichthyoides timorensis is a fish of the shallows, typically found in coastal waters at depths ranging from 1.0 to 15.0 meters. These waters are usually within the neritic zone, the area of the ocean that extends from the shoreline to the edge of the continental shelf. This zone is characterized by its diverse habitats, including coral reefs, seagrass beds, and rocky shores, providing ample opportunities for the Timor Cardinalfish to thrive.

Taxonomy

The species Apogonichthyoides timorensis belongs to the Class: Teleostei, Order: Kurtiformes, and Family: Apogonidae. This classification highlights its position within the larger taxonomic groups, placing it among the ray-finned fishes, a diverse group that constitutes the vast majority of fishes. Within the Apogonidae family, the Timor Cardinalfish shares characteristics with other cardinalfishes, including their slender bodies, large eyes, and often striking color patterns.

Feeding

The Apogonichthyoides timorensis is a carnivore, primarily feeding on invertebrates and zooplankton. This diet reflects its adaptation to life in the shallows, where these small organisms are plentiful. The Timor Cardinalfish uses its small mouth to snatch these prey items from the water column, playing a crucial role in the delicate balance of the marine ecosystem.
