In this article, we will take a detailed look at the different types of these fish, how to set up a comfortable aquarium for them, and what to feed them. You will learn how to create a piece of Papuan nature in your home and enjoy the graceful dance of these living gems.
Popondetta furcata is an unusual and undemanding cactus fish, often chosen by both beginners and experienced aquarists. It stands out for its bright stripes and characteristic forked tail, hence the name “furcata.” It lives in small schools, so it feels better in the company of its fellow creatures. It does not need a large aquarium or complex care — the main thing is to provide clean water, space for swimming, and light plants for shelter. When kept properly, it is active, peaceful, and a joy to watch for a long time.
Habitat and lifestyle
Popondetta furcata is found in its natural habitat only in the eastern part of the island of Papua New Guinea in the province of Oro, near the town of Popondetta, after which the species is named. It was first described in 1953.
Its main habitat is located in the Kwagira and Muga river basins. The fish prefers small freshwater bodies with moderate currents. These are mainly small rivers, streams, and flowing lakes.
Popondetta lives in schools (10-50 individuals) near underwater vegetation at shallow depths. It prefers warm, clean water, but can tolerate extreme conditions if necessary. After the pond dries up, it can survive even in a small puddle with low oxygen levels. The fish can live in salt water for a while, but only for a few days.
They spend most of their lives in the middle and upper layers of the water, searching for food in the form of plankton carried by the countercurrent. In case of danger, the school flees, hiding in the nearest thickets.
Description
The fish has bright, memorable coloring. Its body is elongated, strongly flattened on the sides, and slightly rounded. It somewhat resembles small members of the carp family.
In its natural habitat, it reaches a body length of 6-7 cm. In aquarium conditions, it does not exceed 4 cm. Its coloration is mainly blue-green with yellow, red, and orange hues.
A distinctive feature is their bright yellow fins. The dorsal fin is shifted towards the tail and consists of two parts. The anal fin is significantly longer than the dorsal fin. The pectoral fins are relatively long and wide, which allows them to stay in the current. The tail is short but wide. It is colored yellow and black.
The eyes are located closer to the top of the head. They are large and easily noticeable due to their bright blue color and black pupils. Because of this, the fish is nicknamed the blue-eyed fish.
Sexual dimorphism is manifested in coloration. Males are noticeably brighter and more conspicuous. They have more red and orange colors. Females are not as bright, with yellow predominating in their coloration. Males also have black edging on their tails, which females do not have. In terms of behavior, males are more energetic. They often frolic or fight each other for leadership in the flock. At the same time, they do not harm each other.
Keeping
This species is easy to care for, so it is suitable as an aquarium fish even for beginners. Nevertheless, it is necessary to create favorable conditions that are as close as possible to their natural habitat.
Aquarium
A small school of up to 10 fish should be kept in a 40-50 liter aquarium. If the school exceeds 20 fish, the aquarium should be between 150-200 liters. Water filtration and aeration are essential. These fish also enjoy a slight current.
It is advisable to have an elongated aquarium so that the fish have more space to maneuver. This will reduce stress and provide greater comfort. A lid is needed on top, as the fish may jump out of the aquarium, for example, if they get scared.
Water requirements
The recommended temperature is 20-26°C. While a drop in temperature below 20°C is not critical, an increase is dangerous to life and health. pH level – 6-8, dH – 6-12, hardness – 100-180 ppm. The water should not contain chlorine, ammonia, or other hazardous substances. The water should be changed by 20-30% every week. The tank should be completely cleaned once every two months.
Substrate
Popondetta stays in the upper layers of the water and practically never sinks to the bottom. Therefore, any substrate can be used. Usually it is pebbles or sand. Although the fish is more accustomed to green vegetation, the bottom can be covered with moss and plants.
Decor and plants
Various driftwood, stones, and aquatic vegetation are used as decorative elements. This is one of the most important elements, as the fish must have a secluded place where they can hide in case of danger. Without shelter, the entire school will rush around the aquarium at any sound or sudden movement. As a result, the population may die out.
Plants are placed on the sides, leaving a free area in the center where the fish will swim most of the time. Plants should be floating and as dense as possible.
These can be:
Lighting
The light should be dim, not bright. Direct rays of light scare the fish, and it will try to hide. Also, do not turn the light on or off abruptly, as this greatly frightens the popondetta. As a result, it may jump out of the aquarium or crash into the lid. The light level should change gradually in one direction or another. At night, you can leave a small light or illumination on.
Feeding
This is an omnivorous fish that feeds on phyto- and zooplankton. For this reason, its diet should be as varied as possible.
The following products should be given:
It is recommended to use regular tropical fish food. The food should be as small as possible. The fish cannot swallow or chew large pieces. The food is simply poured onto the surface in small portions so that the school has time to eat most of the food before it sinks to the bottom. Fish do not feed from the bottom at all, so food residues will worsen the sanitary conditions.
Adult fish are fed 2-3 times a day in small portions, young fish can be fed 3-4 times until they grow up.
Reproduction
Spawning occurs simultaneously throughout the entire school. To achieve this, the water temperature is gradually raised by several degrees. The aquarium should contain a large number of floating plants. It is also recommended to cover the bottom with plants, such as Java moss. Females attach their eggs only to aquatic plants.
If the aquarium is spacious enough with plenty of vegetation, there is no need to remove adult fish. In a small aquarium, the eggs and fry will inevitably be eaten. Other fish species must be moved to another aquarium during spawning.
The incubation period lasts 12-15 days. After the fry appear, fresh water should be added frequently and new filters installed.
At first, the fry are fed infusoria, and after 2-3 weeks, they are given daphnia. In the second month of life, they are given standard food for adult fish. Sexual maturity is reached at about 4-5 months.
Compatibility
In general, popondettas behave peacefully towards their relatives and other inhabitants of the aquarium. However, it has been observed that when there are few females in the flock, the males become aggressive. This problem can be solved by increasing the proportion of females to 50-60% of the total number of individuals in the aquarium.
Popondetta furcata gets along well with the following species:
Popondetta should never be kept with cichlids, which are predators and may eat smaller species. Popondetta, in turn, attack shrimp and other crustaceans, which serve as food for them in their natural habitat.

Diseases
In captivity, popondetta rarely gets sick if the aquarium is kept clean and the water is changed regularly. Problems begin when parasites appear in the aquarium. Most often, oodiniosis develops when sanitary standards are violated.
The pathogen is a single-celled parasite that settles on the surface of the fish's body, manifesting itself as a whitish coating and golden dots. This causes the fish to behave anxiously and restlessly. The parasites cause itching and pain, which leads to a decrease in appetite. In the early stages, the disease can be cured with special copper-containing preparations.
In addition, diseases associated with a lack of vitamins and minerals often develop in captivity. Therefore, it is recommended to regularly add vitamin supplements for aquarium fish to their food. This will significantly improve the health and prolong the life of your pets.
