Table of contents


The Honey Blue-eye Rainbowfish (Pseudomugil Mellis) is a stunning and exquisite addition to any community tank. These small, peaceful and active fish make great tank mates, often seen chasing after other fish of similar size. However, it is important to note that males can sometimes harass the females. As a shoaling species, the Honey Blue-eye Rainbowfish thrives in the company of other peaceful fish. However, avoiding keeping them with larger, aggressive, and fin-nipping species is best to prevent unnecessary stress. Their moderately compressed, elongated bodies are coloured in a pale honey hue with bronzy streaks. The males exhibit distinguishable black submarginal bands with white margins on their brownish fins. Their body scales form an attractive latticework pattern, while the females and juveniles have plain, amber bodies with transparent fins. These captivating and elegant fish will surely be a highlight in any aquarium, bringing a sense of vibrancy and energy to the environment.

Natural Habitat

The Honey Blue-eye Rainbowfish is a fascinating aquatic species that can be found in Southern Queensland, Australia. This beautiful fish is known for its limited natural range, which is mainly confined to the so-called Wallum country between Fraser Island and Brisbane. The Honey Blue-eye is known to inhabit tea-colored water, which is often stained from tannins, in lakes, streams, swamps, and creeks. They thrive in slow-moving, almost still currents with nutrient-poor acidic sandy soil. These remarkable creatures are typically found in habitats covered in aquatic vegetation, primarily grassy banks and water lilies. It is fascinating to observe the Honey Blue-eye Rainbowfish in its natural environment and witness how it adapts to the unique conditions of its habitat. This species is a true testament to the wonder and diversity of the aquatic world.


The Honey Blue-eye Rainbowfish is an intriguing species that offers a remarkable opportunity to witness the natural processes of reproduction in the aquatic world. To encourage the healthy development of this species, it is crucial to maintain a suitable aquarium environment and provide a nourishing diet. These fish typically reach sexual maturity at around five months of age and can be bred in either pairs or groups. Ensuring a balanced diet is essential for successful breeding, with live food options providing an excellent source of nutrients. Additionally, a suitable spawning medium, such as java moss or floating plants, should be included in the aquarium. Interestingly, the Honey Blue-eye Rainbowfish is known for its unique breeding habits. Unlike other aquatic species, this rainbow fish prefers to spawn during the afternoon rather than the early morning. The female may release up to 10 eggs per day, but it is important to note that this number may vary. To protect the eggs and fry from potential predators, it is recommended to move the spawning medium to a separate container. Under optimal conditions, the eggs typically hatch within a nine-day period. To ensure the healthy growth and development of the fry, it is recommended to provide them with infusoria as a primary food source until they are mature enough to consume newly hatched brine shrimp.

Diet & feeding

In its natural habitat, the Honey Blue-eye Rainbowfish sustains itself mainly on algae, supplemented by insects and other aquatic invertebrates. When kept in a home aquarium, it is essential to provide a varied and nutritious diet to ensure optimal health and vitality. To maintain a healthy and balanced diet, it is recommended to offer high-quality dry food such as pellets, flakes, and algae wafers. Additionally, frozen and live foods such as daphnia, brine shrimp, and bloodworms should be provided to supplement their diet. These fish typically forage at the surface of the water, making it crucial to ensure that their food is easily accessible and readily available. By providing a well-rounded and nutritious diet, you can help promote the health and wellbeing of your Honey Blue-eye Rainbowfish and ensure that they thrive in their aquarium environment.
