Spotted Croucher

Caracanthus madagascariensis

The Spotted Croucher, Caracanthus madagascariensis, is a small reef-associated fish found in the tropical waters of the Western Indian Ocean, ranging from East Africa to the Maldives and the Chagos Archipelago. These fish are closely associated with coral reefs, where they inhabit the crevices and branches of corals. They have a distinctive appearance with a greyish body adorned with reddish spots. Their body is oval and laterally compressed, covered in small, rough papillae, and they possess a small terminal mouth. The Spotted Croucher is typically found at depths shallower than 40 meters, with most occurrences recorded at depths less than 30 meters. They reach a maximum length of about 5 cm. Their small pectoral fins are adapted for wedging into coral crevices, a behavior that helps them avoid predators and possibly ambush prey. Divers encountering the Spotted Croucher can expect to find them nestled within coral branches. They are harmless to humans and are not targeted for human use. The species is currently listed as Least Concern on the IUCN Red List.
