Natural habitat

Pseudomugil gertrudae is native to the slow-moving waters and wetlands of northern Australia and New Guinea. This species thrives in well-planted environments with ample vegetation, providing hiding places and open swimming areas. Due to their active nature, they appreciate stable water conditions and gentle flow.

Where they are found

The Spotted Blue Eye Rainbowfish is native to the freshwater systems of Australia, particularly in northern regions such as the Northern Territory and Queensland. Their populations can usually be found in well-planted areas, offering them safety from predators and a suitable environment for feeding.

Aquarium care

For aquarium care, Spotted Blue-Eye requires a well-maintained environment with high water quality. Regular water changes and a cycled tank are essential, as these fish are sensitive to water parameter fluctuations. They benefit from a planted tank with plenty of hiding spots to feel secure.

Feeding

Pseudomugil gertrudae is an omnivore that thrives on a varied diet including high-quality micro pellets, crushed flakes, baby brine shrimp, daphnia, frozen cyclops, and small live foods. A diverse diet aids in enhancing their coloration and breeding behavior.

Compatibility

This species is peaceful and can be kept in community tanks with other small, non-aggressive fish. It is best maintained in groups of at least 10 to prevent stress and promote natural behavior.

Breeding

Breeding these fish can be a rewarding endeavor, as they are egg scatterers. Providing fine-leaved plants for spawning, along with stable water temperature and conditions, will encourage them to lay eggs. The eggs hatch in about 7-10 days, and the fry should be fed infusoria until large enough for baby brine shrimp or crushed flake food.
