Honey Blue-eye (Pseudomugil mellis) Care Guide

Pseudomugil mellis is a small honey-coloured blue-eye from acidic, tannin-stained wallum swamps of southeastern Queensland, assessed as Endangered.

Overview

Pseudomugil mellis, the honey blue-eye, is a small fish of the family Pseudomugilidae, described in 1982 by Allen and Ivantsoff. Wikipedia reports a largest recorded male of 3.8 cm, with typical adults of 2.5-3 cm. It is a pale honey-coloured fish with blue eyes and cheeks; males show black submarginal bands with white margins on the dorsal, anal and caudal fins, while females have clear fins.

Taxonomy

  • Family: Pseudomugilidae
  • Genus: Pseudomugil
  • Scientific name: Pseudomugil mellis

Habitat

Found in two disjunct wallum heathland areas of southeastern Queensland, from a swamp near Rockhampton and from lakes and streams between Tin Can Bay and Tibrogargan Creek north of Brisbane. It inhabits slow-moving, mildly acidic water (pH 4.4-6.8) that is either clear or stained with tannin.

Tank requirements

  • Minimum tank volume: 40 L
  • Temperature: 20-26 °C (68-79 °F)
  • pH: 5.5-7.0
  • GH: 2-10 °dGH
  • School size: 8 or more individuals
  • Lifespan: 2-3 years

Diet

Wikipedia reports that algae form the bulk of the diet, with insects and other aquatic invertebrates making up the remainder; the species generally forages at the water surface. In aquaria it accepts small dry foods and fine frozen or live items.

Compatibility

A peaceful, top-dwelling species that forms schools of roughly 25-70 individuals in the wild. Keep in groups of eight or more, ideally with other small, calm blue-eyes; avoid boisterous tankmates.

Conservation status

IUCN Red List: Endangered (assessed 2019), reflecting habitat loss in its restricted wallum range.
