Table of contents


Prepare to be mesmerized by the rare and exquisite beauty of the Popondetta Blue-eye Rainbowfish (Pseudomugil connieae). With their peaceful temperament, remarkable hardiness, and vibrant colouration, these Rainbowfish make a stunning addition to any well-planted or nano aquarium.

When considering suitable tankmates for these magnificent fish, other Rainbowfish species, smaller Barbs, Gobies, Danios, Plecos, and Catfish prove to be excellent companions. The presence of other tankmates can help disperse any potential aggression that may arise from male Popondetta Blue-eyes during spawning conditions.

In their natural habitat, Popondetta Blue-eye Rainbowfish exhibit shoaling behaviour; therefore, it is highly recommended to keep them in a group of at least six individuals, preferably more. By maintaining a larger school, these fish become less apprehensive and present a more captivating and natural display. In addition, the interaction between males and females within the group further adds excitement as males showcase fascinating behaviours.

Creating an ideal aquarium setup for these splendid fish involves incorporating plenty of aquatic plants to cover the sides and background while allowing ample open swimming space in the centre. Dimming the aquarium lighting or introducing an abundance of floating plants serves to subdue the light, enhancing the vibrant colouration of your prized fish.

The Popondetta Blue-eye Rainbowfish boasts an elongated and compressed body adorned with a captivating yellowish-green hue. The dorsal and anal fins showcase a broad outer margin in white or yellow, complemented by a central black stripe. Notably, the first dorsal fin exhibits a striking yellow outer edge. In comparison, females possess smaller fins devoid of intricate markings, and while similarly coloured, they may not exhibit the same level of vibrancy as the males.

Sexual Dimorphism

Distinguishing between male and female Popondetta Blue-eye Rainbowfish is a relatively straightforward task. Males exhibit distinct physical characteristics that set them apart from their female counterparts. Typically, males are slightly larger in size and possess significantly elongated fins, which add to their overall majestic appearance. Moreover, their vibrant colouration surpasses that of the females, further enhancing their visual allure. These noticeable differences in size, fin extension, and colouration provide a reliable means of discerning the male Popondetta Rainbowfish from the female specimens.

How to breed the Popondetta Blue Eye Rainbowfish

Popondetta Blue-eye Rainbowfish, being egg-laying species, exhibit no parental responsibility and, unfortunately, may consume their own eggs and fry if provided the opportunity. However, within a well-appointed aquarium, it is possible for some fry to survive. Spawning is more likely to occur in slightly elevated temperatures.

During the spawning process, females deposit a few eggs daily over several days, attaching them to aquatic vegetation or spawning mops using sticky threads. Individual males may mate with multiple females within a single day. This activity predominantly takes place during daylight hours, with a surge of spawning behaviour observed from late morning to early afternoon. In the controlled environment of an aquarium, breeding can occur throughout the year when the temperature remains consistent.

Two methods can be employed to encourage spawning in Popondetta Blue-eye Rainbowfish. The first method involves isolating a small group of 6 to 8 individuals or a single male with two or three females in a separate breeding tank equipped with an air-powered sponge filter and a suitable spawning medium like nylon mops or aquatic moss. Daily monitoring is necessary, and any discovered eggs should be promptly transferred to a separate rearing tank for incubation and hatching.

Alternatively, a second approach involves maintaining a colony of adults in a more extensive, fully-decorated setup, which allows for natural breeding. In such an environment, well-planted surroundings are essential to facilitate the survival of the fry. Attaching aquatic moss to elevated decor or incorporating floating plants with long roots is recommended to maximise success. While this method may yield fewer results, it is considered more straightforward and reliable, benefiting from stable water conditions and the presence of microfauna that can serve as an initial food source for the fry.

The incubation period for Popondetta Blue-eye Rainbowfish typically spans between 7 and 15 days, influenced by temperature variations. The fry readily accepts nourishment such as baby brine shrimp, microworms, and appropriately sized foods. It is advisable to provide small, frequent feedings at least twice a day, promptly removing any uneaten food to prevent accumulation in the rearing tank, which can lead to elevated mortality rates. Small water changes are crucial to maintaining water quality and mitigating potential issues caused by leftover food.

Engage in the art of fostering the next generation of Popondetta Blue-eye Rainbowfish, employing these approaches to create a conducive breeding environment and ensure the successful rearing of these remarkable fish.

Diet & feeding

In their natural habitat, the dietary preferences of Popondetta Blue-eye Rainbowfish centre around phytoplankton, zooplankton, and various invertebrates. Hence, it is crucial to provide them with appropriately sized meals when it comes to their nutrition within the confines of an aquarium. Offering a diverse range of live, frozen, and freeze-dried foods ensures a well-rounded diet for these captivating fish. To replicate their natural feeding habits, consider incorporating nourishing options such as brine shrimp, bloodworms, daphnia, cyclops, and microworms. Additionally, Popondetta Blue-eye Rainbowfish readily accept small dried foods like crushed flakes, granules, and micropellets, further contributing to their dietary needs and overall well-being.
