Popondetta Blue Eye Rainbowfish (Pseudomugil connieae)

The rare and handsome Popondetta Blue-eye Rainbowfish, Pseudomugil connieae, are a peaceful, hardy, active species with stunning colouration.

These Rainbowfish make excellent members of a well-planted or nano aquarium. Suitable tankmates for these fish could include other Rainbowfish species, smaller Barbs, Gobies, Danios, Plecos and Catfish. The males of this species can become relatively aggressive when in spawning conditions, so having other tankmates is ideal for dispersing any aggression.

Popondetta Blue-eye Rainbowfish are a shoaling species in nature; therefore, it would be best if you kept them in a group of at least six individuals, preferably more. Keeping these fish in more significant numbers will make them less frightened and result in a far more natural-looking display. Males will also display exciting behaviour when in the company of females.

The ideal aquarium setup for these fish would be an aquarium with plenty of aquatic plants covering the sides and background with plenty of swimming space in the middle. In addition, a dimly lit aquarium or plenty of floating plants to subdue the light will bring out the best colouration of your fish.

An elongated and compressed yellowish-green body characterizes Popondetta Blue-eye Rainbowfish. Its dorsal and anal fins have a broad white or yellow outer margin and a central black stripe. Also, the first dorsal fin has a yellow outer edge. In contrast to the males, females have smaller fins with no intricate markings and are similarly coloured, but not as vibrantly.

In the home aquarium, the Popondetta 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 straightforward to distinguish the males from the female Popondetta Rainbowfish. Males are usually slightly larger than females, have much more extended fins and are always more brightly coloured than females.


Breeding the Popondetta 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.
