An updated guide to some of the most enigmatic and often misidentified of coral-dwelling fishes aims to provide a comprehensive description of the main diagnostic features for the majority of the species distributed throughout the Indo-Pacific region, including live colouration descriptions, known coral hosts, reef habitats and geographic ranges for each species.
The πΊπππππππ genus, well known and loved by reef hobbyists as the Coral Gobies, are diminutive obligate coral-dwelling cryptic fishes. These fascinating little fishes form a mutualistic relationship with a host of scleractinian species, making them integral to coral reef ecosystem functioning. Despite this, they are often omitted from fish assemblage studies, biodiversity surveys and coral reef fish guides due to confusion on species identification. Coral Gobies can be observed occupying host corals of the genera π΄πππππππ, ππ‘π¦πππβπππ, π»π¦ππππβπππ and πΈπβπππππππ on coral reefs in the Pacific and Indian Oceans and are known for their cryptic behaviours. Distinguishable by subtle body colouration and colour markings there are 31 described species, 26 of which have undisputed species status and sufficient data to include in this guide.
