scientifically known as Gobiodon histrio, is a small fish species belonging to the family Gobiidae. It is native to the tropical waters of the Indo-Pacific region, including the Red Sea, the Great Barrier Reef, and the Indian Ocean. Let's explore some key aspects of the Two-Lined Coralgoby:

Fish Family: The Two-Lined Coralgoby belongs to the family Gobiidae, which is one of the largest families of fish. Gobies are known for their small size, bottom-dwelling behavior, and diverse adaptations.

Size: The Two-Lined Coralgoby is a relatively small fish, with adults typically reaching a maximum length of around 5 centimeters. It has a slender body and a relatively large head in proportion to its size.

Basic Shape/Features: The Two-Lined Coralgoby has a streamlined and elongated body, which allows it to navigate through coral reefs and other complex habitats. It has two dorsal fins, a rounded caudal fin, and small pectoral fins.

Body Coloration/Pattern: The Two-Lined Coralgoby displays a striking coloration and pattern. It has a bright yellow body with two prominent blue lines running horizontally along its sides, giving it its common name. The combination of yellow and blue serves as a warning coloration to potential predators, indicating that it is venomous and should be avoided.

Social Behavior: The Two-Lined Coralgoby is a social and territorial fish species. It forms small groups or pairs and inhabits coral reefs, where it seeks shelter among branching corals. It has a mutualistic relationship with the coral, as it protects the coral by removing harmful algae and defends its territory from intruders.

Fashion: While fish do not possess the concept of fashion in the human sense, the Two-Lined Coralgoby showcases its vibrant coloration and patterns as a form of visual communication. The bright yellow and blue coloration serves as a warning to predators, advertising its venomous nature and discouraging potential threats.

The Two-Lined Coralgoby is a fascinating fish species that adds vibrant colors to the coral reef ecosystem. With its unique coloration, slender body, and social behavior, it plays an important ecological role in maintaining the health of coral reefs. Its ability to coexist with corals and provide mutual benefits exemplifies the intricate interconnections found within marine ecosystems.
