Overview

This is the most widespread blue-eye in Australia, described from around Sydney. Highly variable between populations, with at least 15 recognised geographic forms, it may be split into several species in the future.

Scientific name
Pseudomugil signifer Kner, 1866
Classification
Atheriniformes › Pseudomugilidae
IUCN Red List
Least concern (LC)

Natural habitat

Endemic to eastern Australia: from Cape York Peninsula (Queensland) to Lake Merimbula (New South Wales), and a few Torres Strait islands

Observations (GBIF) and localities Native countries Rivers and lakes

It is found in the sea as well as in fresh water: tidal mangrove creeks, salt marshes, but also clear, cool forest streams, sometimes fast-flowing, and a few acidic blackwaters. The temperature varies from 15 to 28 °C depending on the season and latitude.

Behaviour

Most forms are peaceful and suit selected community tanks, with cyprinids, gobies, Eleotridae and small rainbowfish of similar size and temperament. In a shoal of at least 8 to 10, more if possible, it is less nervous. Food to match its size, mostly live (Daphnia, Moina, Artemia nauplii), and fine floating dry food.
