📖 Overview

Pomacentrus rodriguesensis is currently known only from Rodrigues. It is relatively common in the lagoon at depths between 9-18 m on reefs that contain mainly Acropora corals that are affected by silt deposition. Their territorial behaviour suggests that, although they may not dramatically modify the benthic reef environment, they may promote the biomass of their preferred food algae. Life history characteristics for the family specify that this group is oviparous, with distinct pairing during breeding . Eggs are demersal and adhere to the substrate . Males guard and aerate the eggs .
