The Pseudomugilidae, the blue-eyes, are a subfamily of atheriniform fish in the rainbowfish family Melanotaeniidae. [1] They inhabit fresh and brackish water in Australia, New Guinea and nearby smaller islands. [2] Blue-eyes are small fish, typically no more than 5 cm (2.0 in) in length.
The forktail blue-eye (Pseudomugil furcatus) is a diminutive species of rainbowfish in the subfamily Pseudomugilinae. It is endemic to Papua New Guinea, south-east of Popondetta, where it is found in rainforest streams. It used to be placed in the genus Popondetta, and even separated as Popondichthys, but this is now considered erroneous.

Rainbowfish usually eat floating flakes in captivity, because in the wild they will often eat insects floating on the surface. In a home setting, these fish need well-oxygenated water with a pH level of 6.8 – 7.2, optimal temperatures varying between 72 and 82 °F (22–28 °C), and plenty of aquatic plants to give them hiding places amid ...
There are currently 16 recognized species in this genus: Pseudomugil connieae (G. R. Allen, 1981) (Popondetta blue-eye); Pseudomugil cyanodorsalis G. R. Allen & Sarti, 1983 (Neon blue-eye)
The Pacific blue-eye generally reaches a total length of around 3–3.5 cm (1 + 1 ⁄ 8 – 1 + 3 ⁄ 8 in) long; males can reach 8.8 cm (3 + 1 ⁄ 2 in) and females 6.3 cm (2 + 1 ⁄ 2 in). [4] The size of Pacific blue-eyes found north of the Burdekin Gap increases directly with distance from the gap, males and females being the same size.
Total length measurements are used in slot limit and minimum landing size regulations. Fishery biologists often use a third measure in fishes with forked tails, called Fork length ( FL ), the length of a fish measured from the tip of the snout to the end of the middle caudal fin rays, and is used in fishes in which it is difficult to tell where ...
