Honey Blue Eye Rainbowfish (Pseudomugil Mellis)

Honey Blue-eye Rainbowfish are small stunning looking fish that make an excellent addition to a community tank. They are generally very peaceful and active chasing around other fish that are similar in size. However, the male can harass the female sometimes.

The Honey Blue-eye Rainbowfish are a shoaling species that does well with other peaceful species. It would be beneficial for these fish if you did not keep them with more extensive, aggressive, fin-nipping species, this would avoid any unnecessary stress for the fish.

These fish have moderately compressed and elongated bodies that are a pale honey colour with bronzy flecks. Males have brownish coloured fins that display distinct black submarginal bands and white margins.

The body scales are lightly edged with black forming an attractive latticework pattern. The female and juveniles have a plain, amber-coloured body with transparent fins. They have two dorsal fins that are close together, the first being much smaller than the second.

Honey Blue Eye Rainbowfish

Habitat

You can find Honey Blue-eye Rainbowfish in Southern Queensland in Australia. Its natural range is quite limited and consists of so-called Wallum country between Fraser Island and Brisbane. They inhabit tea-coloured water stained from tannins in lakes, streams, swamps and creeks with slow-moving almost still currents with nutrient-poor acidic sandy soil. Their habitats are covered in aquatic vegetation, mainly grassy banks and water lilies.

Diet & Feeding

In the wild algae forms the bulk of the Honey Blue-eyes diet, with the remainder made up of insects and other aquatic invertebrates. In the home aquarium, you should provide them with a varied diet of high-quality dry food such as pellets, flakes and algae wafers as well as frozen and live foods such as daphnia, brine shrimp and bloodworm. These fish generally forage at the surface of the water.

Sexual Dimorphism

It is effortless to distinguish male from female Honey Blue-eye Rainbowfish. Fully grown the males have distinct black submarginal bands present on his anal, caudal and dorsal fins and white margins. Some males also form a short filament in their first dorsal fin. In contrast, juveniles and females have a plain light-amber coloured body with small unmarked translucent fins.

Breeding

Honey Blue-eye Rainbowfish are seasonal spawners and usually spawn between September to January.

The Honey Blue-eyes reach sexual maturity when they get around five months old or around 2 cm in size. You can breed them in either pairs or groups. Larger females produce many more eggs than smaller ones. in captivity males exhibit territorial behaviour guarding the spawning site against imposing conspecifics.

You should condition the fish with plenty of live or frozen foods before spawning and use a separate breeding tank with small clumps of fine-leaved plants such as java moss; this can be used as a spawning medium.

During spawning, the male raises his fins and swims around in zigzag patterns to block the female’s retreat.

Unlike many other Rainbowfish that spawn in the early morning, the Honey Blue-eye is more likely to generate in the afternoon. The female Honey Blue-eye will only release a small number of eggs each day, usually 5-10 eggs every 24 hours. Once laid, you should place the eggs in a separate tank; otherwise, the adult fish may consume them.

Spawning can last around 7 to 9 days, and a total of up to 125 eggs can be released over that period.

The eggs will typically hatch within 5 to 14 days, depending on the water temperature. It would be better if you fed the fry with infusoria type foods or similar until they are large enough to consume freshly hatched baby brine shrimp.
