Red Neon Blue Eye Rainbowfish (Pseudomugil luminatus)

The Red Neon Blue Eye Rainbowfish is very rare, and it is one of the most gorgeously coloured and outstanding nano fish. These fish are a peaceful species; however, they are unsuitable for the general community aquarium because they are very small and will easily be outcompeted for food.

These Rainbowfish are best maintained in a species only aquarium or alongside fish that are similar in size, nature and share the same water requirements. The best tankmates for these fish would be adult Dwarf Shrimp and other Invertebrates.

Red Neon Blue Eye Rainbowfish are a shoaling species that you should keep in groups of at least eight individuals, ideally more. Keeping them in more significant numbers will make the fish less nervous and result in a more efficient, natural-looking display. The males will also display some fascinating behaviour and show their best colours as they compete for female attention.

These fish will fare much better in a densely planted aquarium with floating plants and driftwood roots or branches; this will help diffuse the light that these fish will appreciate and add a more natural feel.

Red Neon Blue Eye Rainbowfish exhibit bright reddish-orange colouration on their bodies, and they have a light blue stripe down their back as well as blue rings around their eyes. In addition, their fins have widely scattered black spots and the tips of their caudal fin lobes, and the upper edge of pectoral fins have prominent white to yellow markings.

Natural Habitat of the Red Neon Blue Eye Rainbowfish

Red Neon Blue Eye Rainbowfish have only been found in the vicinity of Timika in the capital of Mimika Regency, Papua, Indonesia, in Southeast Asia. They inhabit swamps with murky, slow-flowing waters and submerged dense vegetation.

What to feed the Red Neon Blue Eye Rainbowfish

In the wild, Red Neon Blue Eye Rainbowfish eat zooplankton, phytoplankton, and invertebrates. In the aquarium, they fare best with a diet comprised of live and frozen food such as Daphnia, Moina, Brine shrimp and microworm supplemented with high-quality, small, floating dried foods such as crushed flake or fine granules. It will help if you remember that these are very small fish with tiny mouths.

How to Sex the Red Neon Blue Eye Rainbowfish

It is effortless to differentiate between male and female Red Neon Blue Eye Rainbowfish. Males display bright neon red to reddish-orange and blue colouration on their bodies and fins, especially while they are competing with other males. The second anal and dorsal fins of males become very extended and fan-like as they mature. Females are usually smaller with shorter fins but still display some vibrant colouration.

How to Breed the Red Neon Blue Eye Rainbowfish

Red Neon Blue Eye Rainbowfish are an egg-laying species that exhibit no parental care and will consume their eggs and fry if given an opportunity.

Spawning is more likely to occur in warmer water, with the females attaching a few eggs daily for several days on aquatic vegetation or decor. An individual male can mate with multiple females during a single day.

There are two methods that you can use for breeding these fish. The first involves isolating a small group containing a single male and two or three females into a breeding tank with an air-powered sponge filter and a spawning medium; this can be either moss or spawning mops. You should take the medium several times a day, and you should move any eggs into a separate container for incubation and hatching.

The alternative method is to maintain a colony of adults in a larger, fully-decorated set-up that should allow some fry to survive if well-planted.

Since these fish spend the early part of their life close to the water surface, aquatic mosses attached to decor high in the water column produce the most favourable results. Still, floating plants with trailing roots are also recommended.

The second approach does not result in a very high yield but is more straightforward and more reliable. The reason for this is because established, planted aquariums facilitate relatively stable water conditions, and microfauna can constitute a valuable early food source for babies.

The incubation period is usually around ten days depending on the temperature of the water. After that, the fry will require microscopic food such as Paramecium for approximately five days before they’re able to accept baby brine shrimp, microworms, and similarly-sized foods. You can also raise them by using good quality powdered dry products. After that, the growth rate of the fry usually is relatively fast.

Dirty water can result in high mortality; therefore, it is essential that you perform regular small water changes and do not allow any uneaten food to accumulate in the rearing tank.
