Yellowtail Damselfish care guide

Yellowtail Damselfish (Chrysiptera parasema) — minimum tank 100 L, temperature 24-28 °C, pH 8-8.4.

Overview

The Yellowtail Damselfish (Chrysiptera parasema) is a small Indo-Pacific damselfish with a deep electric-blue body and bright lemon-yellow tail. It is one of the most peaceful members of its family and is among the standard hardy beginner marines.

Taxonomy

  • Family: Pomacentridae
  • Genus: Chrysiptera
  • Scientific name: Chrysiptera parasema

Habitat

Occurs on coral-rich slopes and lagoon reefs of the western Pacific, from the Philippines and Indonesia to the Solomon Islands, typically at depths of 1-16 metres among branching Acropora corals where small groups shelter close to the substrate.

Tank requirements

  • Minimum tank volume: 100 L (26.4 US gal)
  • Adult size: 5-7 cm
  • Temperature: 24-28 °C (75-82 °F)
  • pH: 8-8.4
  • GH: 8-12 °dGH
  • Water flow: moderate
  • Lifespan: 5-8 years
  • Salinity: SG 1.024-1.026
  • Carbonate hardness (dKH): 8-12

Diet

A planktivore and omnivore in the wild, picking zooplankton from the current and grazing on algae. In aquaria it accepts marine flake, micro-pellets, frozen mysis and brine shrimp; offer multiple small feedings per day.

Compatibility

Unusually peaceful for a damselfish but still mildly territorial; can be kept in small groups of three or more added simultaneously to a tank with abundant rockwork. Compatible with clownfish, Royal Gramma, Banggai Cardinalfish, gobies and small wrasses.

Reef compatibility

Reef-safe. Does not nip corals or sessile invertebrates and is among the few damselfish recommended for mixed reef systems.

Breeding

A demersal egg-layer. Males prepare and guard a small substrate nest where the female deposits adhesive eggs; the male tends the clutch through hatching, which produces pelagic larvae. Captive rearing is uncommon.

Conservation status

IUCN Red List: Least Concern. The species is common throughout its range and widely collected for the aquarium trade with no documented population decline.
