Spring Chromis

📖 Overview

Adults inhabit steep outer reef slopes and drop-offs with rocky outcrops and small caves and holes, often in association with limestone talus; usually observed in pairs or small groups, feeding low in the water column, and are generally abundant where they are found . Oviparous, distinct pairing during breeding . Eggs are demersal and adhere to the substrate . Males guard and aerate the eggs .

🔬 Taxonomy

🐟 Physical Description

Dorsal spines (total): 12 - 13; Dorsal soft rays (total): 11 - 12; Anal spines: 2; Anal soft rays: 12. This species is distinguished by the following characters: Dorsal rays XII-XIII, 11-12, usually XIII, 12; anal rays II, 12; pectoral rays 17-18, usually 18; spiniform caudal rays 3; tubed lateral-line scales 13-15, rarely 16; gill rakers 6-8 + 18-21 (total 26-28, rarely 25); body depth 1.65-1.9 in SL. The color when fresh is pale slate blue (bright pale green in life) with a white spot (sometimes two white spots) roughly the size of a scale mid-laterally on the body; malachite green area above orbit and in inter-orbital space and nape; the dorsal and anal fins with bright distal border of pale turquoise blue .: short and / or deep; Cross section: compressed.
