Intermediate Cardinalfish

Cheilodipterus intermedius

The Intermediate Cardinalfish is a reef-associated species found in the Western Pacific, ranging from Japan south to Australia and east to the Solomon Islands. It typically inhabits depths from 2 to 15 meters, though it can be found up to 20 meters deep. This species is known for its elongated, oval body shape, and distinct dark stripes that are narrower than those of similar species. Juveniles and sub-adults can be identified by a large yellow area on their caudal peduncle, marked by a small black spot. Intermediate Cardinalfish are solitary creatures often found in caves over sandy or muddy bottoms. They are mouthbrooders, with distinct pairing behavior observed during courtship and spawning. This species is harmless to humans and is not currently evaluated for any specific human use. Divers encountering the Intermediate Cardinalfish may find them in secluded areas of the reef, often in caves or crevices. They are listed as Least Concern by the IUCN.
