Limbaugh's Chromis

Chromis limbaughi

Limbaugh's Chromis, also known as the blue and yellow damselfish, is a small ray-finned fish found in the family Pomacentridae. It exhibits a coloration with a deep blue body that transitions to bright yellow near the dorsal and caudal regions. This species can be distinguished from similar Chromis species by its 13 dorsal fin spines and the presence of distinctive dark spots on the upper portion of the pectoral fin base. The fish typically measures up to 11.3 cm in length. Limbaugh's Chromis inhabits rocky and coral reef systems in the Gulf of California, extending as far south as Banderas Bay, Mexico. It is a non-migratory species that prefers subtropical waters, with a depth range of 4 to 75 meters. The fish forms small schools above the rocky bottom, where it feeds primarily on zooplankton and fish eggs. Breeding occurs through distinct pairing, with males guarding and aerating the demersal eggs that adhere to the substrate. Limbaugh's Chromis is known for its mild-mannered behavior compared to other damselfish, making it a popular choice in the aquarium trade. The species is listed as 'Least Concern' by the IUCN Red List, though it is under special protection by the Mexican government due to its significance in the aquarium industry.
