Honey Blue Eye Rainbowfish (Pseudomugil Mellis)

The exquisite Honey Blue-eye Rainbowfish, Pseudomugil Mellis are small stunning, looking fish that make an excellent addition to a community tank. They are typically 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. However, 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.

They have moderately compressed, elongated bodies that are pale honey in colour with bronzy streaks. The fins of males are brownish-coloured with distinct black submarginal bands and white margins.

An attractive latticework pattern forms on the body scales. The female and juveniles have a plain, amber-coloured bodies with transparent fins.

Feeding

In the home aquarium, the Honey Blue Eye Rainbowfish will readily accept most good quality dried foods such as granules, flakes and sinking pellets. These modern food products have been developed to provide all adequate nutrition to maintain your fish's health and dietary requirements.

Providing additional foodstuffs such as live, frozen, and freeze-dried meals such as bloodworm, daphnia, and tubifex once or twice a week will provide additional benefits to your fish's health and well-being but is not a must for this fish.

It should be noted that bloodworms should only be given as an occasional treat and should not be used as the staple diet as they are difficult for fish to digest and can potentially cause blockages.

This fish is an omnivore in the wild, meaning it will consume some vegetable matter. Although most modern fish foods take this into account and include them in their products, you can still supplement your fish's diet with blanched vegetables such as spinach, broccoli, and zucchini. Ensure you do not overfeed your fish and remove any leftovers the following day.

Sexual Dimorphism

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

Breeding

Breeding the Honey Blue Eye Rainbowfish is straightforward once these fish are happily established and settled into your aquarium. You will need a mature pair or group of males and females, along with a spawning mop, preferably floating at the top of the aquarium downwards to the substrate.

Despite spawning year-round, Rainbowfish lay many eggs at the beginning of the rainy season. In addition, temperature increases, and live and frozen foods often encourage spawning.

Check your spawning mops daily for any eggs that have been deposited and either remove the eggs from the mop or, better still, remove the entire mop to avoid contamination of the Rainbowfish eggs.

Tip: Have several spawning mops at hand so you can place a fresh spawning mop into the aquarium while you wait for the eggs to hatch on the other mop/s.

Place the spawning mop with eggs still attached into a separate small cycled aquarium with a sponge filter for flow, and add a few drops of Methylene Blue (Methylene Blue helps prevent fungal infections of eggs).

Your rainbowfish Eggs will hatch within 7 to 18 days, depending on the species and the temperature. We recommend 27°C = 80.6°F for the fastest development of fry.

Once the Rainbowfish fry hatch, they absorb their yolk sacs quickly and become free swimming, moving towards the water's surface. Once the fry reaches the water's surface, you can start feeding. We recommend feeding on Micorworm (the most straightforward live food to culture) and decapsulated brine shrimp egg powder several times a day while being careful not to overfeed and pollute the water column.

After a week or two, you can start to add newly hatched brine shrimp, but this isn't necessary to achieve a high success rate in our experience.

Rainbowfish fry grows slowly, so you should expect to wait several months before the fry is large enough to be added to the adult colony.
