Pseudoglyphidodon

Pseudoglyphidodon is a genus of damselfish belonging to the family Pomacentridae. The species within this genus are small, marine ray-finned fish. They are characterized by their vibrant coloration, often displaying shades of blue, yellow, and white. These fish are typically found in tropical and subtropical waters of the Indo-Pacific region, inhabiting coral reefs and rocky areas. Pseudoglyphidodon species are generally herbivores or omnivores, feeding on algae, zooplankton, and small invertebrates. They are known for their territorial behavior, especially during breeding season, and can be quite aggressive in defending their chosen patch of reef. The genus name itself is derived from Greek, with "pseudo" meaning false, "glyph" referring to carving or inscription, and "odon" meaning tooth, likely referencing specific anatomical features of the teeth. Like many damselfish, Pseudoglyphidodon species play a role in the reef ecosystem, serving as prey for larger fish and influencing algal growth through their grazing habits. Due to their small size and often secluded habitats, they are not of major commercial fishing importance, though some species may be kept in aquariums by enthusiasts.
