What is pacific blue eye?

The Pacific blue-eye, also known as Pseudomugil signifer, is a small freshwater fish species that belongs to the family Pseudomugilidae, found in Australia and Papua New Guinea. These fish are commonly found in clear, slow-moving or still waters, such as streams, ponds, and creeks.

Pacific blue-eyes are distinguished by their vibrant blue coloration, with a golden stripe along their sides, and the males are typically brighter in color than females. They can grow up to 5cm in length and have a lifespan of around four years.

These fish are omnivorous, feeding on a variety of small invertebrates including crustaceans, insect larvae, and worms. They also consume algae and other plant matter.

Pacific blue-eyes are popular among aquarium hobbyists due to their striking appearance and peaceful nature. They are relatively easy to care for and require a minimum tank size of 20 liters with a pH range of 6.5-7.5 and a water temperature between 22-26°C.

In the wild, Pacific blue-eyes are not of conservation concern, but there have been reports of populations declining due to habitat loss and introduced predators in some regions.
