Panamic sergeant major
📖 Overview
Adults inhabit rocky and coral reefs . Usually in large aggregations. These diurnal feeders feed on plankton at the surface or mid-water; also graze on benthic invertebrates and algae on the reef. Breed during early summer in the Gulf and continues throughout the summer until fall. This fish is a warm-water, stenothermal species. Juveniles of second year class have been observed cleaning schools of striped mullet, halfbeaks and needlefish . 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): 13; Dorsal soft rays (total): 12 - 13; Anal spines: 2; Anal soft rays: 10 - 13. With black spot on pectoral fin base.: short and / or deep; Cross section: compressed.
🌀 Behaviour
Behavioural data for Panamic sergeant major is currently being reviewed.
🦐 Diet
These Eastern Pacific damselfish are feeders whose diet consists mainly of plankton in the pelagic zone and mid-water, but they also graze on benthic invertebrates and algae on their coral reef habitat. These feeding tendencies make them an omnivorous species. The physical structure of the A. troschelii mouth is one that it small but conveniently located so that it can easily feed on small plankton suspended in the water column and small bits of algae attached to pieces of benthic structure.
🥚 Reproduction
Oviparous, distinct pairing during breeding . Eggs are demersal and adhere to the substrate . Males guard and aerate the eggs .
