DISTRIBUTION/HABITAT: S. nematoptera is found in the Indian and western Pacific oceans often in reef areas of bays and lagoons along with other members of their species, sheltered among branches of Porites spp.

DIET IN THE WILD: The Pajama Cardinalfish feeds on small fish and crustaceans. At night, it leaves the protection of coral shelter to feed along the bottom at about 15 m (50 feet) deep.

REMARKS: Note the large eyes, a common feature of nocturnal fishes that allows them to gather low light images. They are nocturnal and shelter during the day.

 Ostorhinchus sealei  (Apogon sealei) 

 

GENERAL CHARACTERISTICS:  Length 80mm, (3.15 inches). Pale yellow with a  pair of thin brown stripes on the upper side and a dark spot on mid tail base. Two short orange bars in bluish white patch on gill cover.

DISTRIBUTION/HABITAT: Malaysia to the Solomon Islands, north to the Philippines, Palau, and south to Ashmore Reef, Australia. Usually found on coastal fringing reefs or patch reefs to a depth of 25 m (80 feet). It is often found in pairs or in groups among branching corals such as Acropora. 

DIET IN THE WILD: Individuals shelter in amongst the coral during the day and come out to feed at night on zooplankton and benthic invertebrates.

REPRODUCTION and DEVELOPMENT: This species demonstrates distinct pairing during courtship. The males mouthbrood the fertilized eggs until hatching is ready to occur.

LOCATION:  Philippine Coral Reef

Cardinalfish general information.  

Found in the Atlantic and Indo-Pacific oceans, cardinalfishes are primarily marine, though some are found in brackish waters and a few in freshwater streams. Many species inhabit reef flats, lagoons, and seaward reefs to 60 feet (18 m).
The family is characterized by two widely separated dorsal fins, large eyes, short snouts, double-edged preopercula and a moderately large oblique mouth. The name derives from the red coloration of some well-known species, though many are drab or striped.
Most remain hidden during the day, and then disperse over the reef at night to feed on zooplankton and small benthic invertebrates, always remaining close to the substrate. Males of many species are mouth brooders.
