Sapphire Damsel (Pomacentrus pavo) Care Guide
Pomacentrus pavo is an Indo-Pacific reef damselfish reaching about 8.5 cm, feeding on zooplankton and filamentous algae.
Overview
Pomacentrus pavo, the sapphire damsel, is a marine damselfish of the family Pomacentridae. FishBase records a maximum size of 8.5 cm standard length. It is a widespread reef-associated species of the Indo-Pacific.
Taxonomy
- Family: Pomacentridae
- Genus: Pomacentrus
- Scientific name: Pomacentrus pavo
Habitat
FishBase reports the species across the Indo-Pacific from East Africa to the Tuamotu Islands, north to Taiwan and south to Lord Howe Island. It lives at depths of 1–18 m, inhabiting sandy lagoon reef areas, patch reefs, coral heads and rubble zones, and is commonly found near jetty structures.
Tank requirements
- Minimum tank volume: 150 L (about 40 gal)
- Temperature: 24–26 °C (75–79 °F)
- pH: 8.1–8.4
- GH: 8–12 °dGH
- Lifespan: 5–10 years
Diet
According to FishBase the sapphire damsel feeds on zooplankton and filamentous algae, with a trophic level of 3.0. In aquaria it accepts prepared, frozen and small live foods together with algae-based feeds.
Compatibility
FishBase describes this as a diurnal species typically observed in groups. As an aggressive, mid-water Pomacentrus it can defend territory in smaller tanks. Robust tankmates such as tangs, wrasses and (with caution) triggers are generally suitable; slow, shy fish and additional damsels in small tanks should be avoided.
Breeding
Reproduction is oviparous with distinct pairing. FishBase reports that the eggs are demersal and substrate-adhering and that males guard and aerate them. Captive breeding is considered an expert-level undertaking.
Conservation status
IUCN Red List: Least Concern (assessed 4 October 2021, per FishBase).
