Yellowstriped cardinalfish

📖 Overview

Inhabits sheltered clear water areas of lagoon and seaward reefs from depths of 1 to at least 49 m. Found in small or large aggregations under ledges, in holes, or even among long spines of sea urchins. Feeds on planktonic crustaceans and small invertebrates. Has been reared in captivity .

🔬 Taxonomy

🐟 Physical Description

Dorsal spines (total): 8; Dorsal soft rays (total): 9; Anal spines: 2; Anal soft rays: 8. Bluish silver in color, with 6 orange-yellow stripes, including a short post ocular stripe. Sub-equal along abdomen, and midlateral stripe ends into pinkish to orange spot on caudal fin base (red at night) . Greatest depth of body 2.7-3.0 in SL .: fusiform / normal; Cross section: compressed.

🌀 Behaviour

Behavioural data for Yellowstriped cardinalfish is currently being reviewed.

🦐 Diet

O. cyanosoma is mainly a nocturnal planktivore, emerging from hiding in coral caves and crevices to feed by hovering just above sandy microhabitats on coral reef flats. By defecating during the daytime in a non-feeding microhabitat, O. cyanosoma probably helps cycle reef nutrients around different communities on the reef. It appears to prefer to eat small benthic sergestid crustaceans rather than the planktonic larvae to be found higher in the water column. However, seasonal or sampling effects may play a role in defining the diet, since in certain years, certain sites appear to suggest that O. cyanosoma is actually eating significant amounts of planktonic copepods and crustacean larvae. Although its wide mouth gape may be well suited to eating benthic prey, consumption of varying types of prey by cardinalfishes with different mouth shapes appears in reality to be better correlated with varying availability (i.e. many mouth shapes can still make generalist species).
