Orange-lined Cardinalfish

Taeniamia fucata, also referred to as the orange-lined- or painted cardinalfish, is a marine species indigenous to reef ecosystems spanning from northern 🇦🇺 Australia and 🇵🇬 New Guinea, across the 🌊 Indian Ocean to the eastern coast of Africa, as well as the 🌊 Pacific Ocean encompassing the 🇲🇭 Marshall Islands, 🇼🇸 Samoa, 🇹🇴 Tonga, and the Ryukyu Islands (🇯🇵 Japan). Prior to 2013, this species was recognized under the scientific name Archamia fucata.

The orange-lined cardinalfish has a relatively small body, typically reaching a maximum length of around 7 centimeters. Its body is elongated and compressed, with a slightly rounded outline. This shape allows the fish to navigate easily through coral crevices and other tight spaces within the reef.

One of the most striking features of the orange-lined cardinalfish is its coloration. The body is predominantly orange, with vivid vertical lines running along its sides. These lines are usually black or dark brown and provide excellent camouflage amidst the coral reef. Additionally, the fish has a dark spot near the base of its tail, which helps further deter potential predators.

Orange-lined cardinalfish prefer to inhabit sheltered areas of the reef, such as coral ledges, caves, and crevices. They form small groups or pairs, often found hiding among the branches of branching corals or within the gaps of coral colonies. These hiding spots offer protection and security for the fish, allowing them to feed and reproduce safely.

Feeding habits of the orange-lined cardinalfish consist mainly of small crustaceans, plankton, and other tiny invertebrates. They have relatively large mouths that enable them to capture small prey effectively. The fish tends to feed during the night, using their excellent vision to hunt within the dark recesses of the reef.

Breeding behavior in orange-lined cardinalfish is quite interesting. Males attract females by making clicking sounds and displaying vibrant colors. Once the female is ready to reproduce, she lays eggs that are then fertilized by the male. The male then guards and aerates the eggs by fanning them with his pectoral fins until they hatch.

Overall, the orange-lined cardinalfish is a captivating species that adds beauty and diversity to the 🌊 Red Sea's underwater ecosystem. Its striking coloration, unique patterns, and interesting behavior make it a highly sought-after fish for aquarium enthusiasts and a joy to observe in their natural environment.
