maintenance, care, compatibility

Congo (lat. Phenacogrammus interruptus) is a shy, but incredibly beautiful aquarium fish.

Perhaps one of the most luxurious haracin. The body is very bright, fluorescent colors, and the fins are a gorgeous veil.

Tetra Congo is a very peaceful, schooling fish that grows up to 8.5 cm. For a flock of these fish you need a large aquarium so that there is a free place for swimming, but in order that they can fully reveal their beauty.

For Congo, soft water and dark ground are best. They feel more comfortable in an aquarium with a dim light and plants floating on top, with such lighting their color looks most advantageous. The Congo is rather shy fish and should not be kept with aggressive or very active species.

And they are very shy while eating and can start eating only after you leave the aquarium.

Congo (Phenacogrammus interruptus) was described in 1899. Quite widespread in nature and not under threat. Congoes live in Africa, in Zaire they mostly inhabit the Congo River, which is characterized by slightly acidic and dark water.

They live in flocks, feed on insects, larvae, and plant debris.

Congo is a rather large fish for tetras, it can grow up to 8.5 males and up to 6 cm females. Life expectancy from 3 to 5 years. In adult congo, the color is like a rainbow, which shimmers from the blue on the back, golden in the middle and blue again at the abdomen.

Voile fins with white edging. Describing it is difficult, easier to see once.

In nature, Congo mainly eats insect worms, larvae, aquatic, and also plant food. In an aquarium, feeding it is not difficult. Almost all types of feed are good. Flakes, pellets, live and frozen feed, the main thing that the fish could swallow them.

Of the possible problems, the congo is a rather timid fish, they do not keep up with their brisk neighbors and may even not take food while you are near.

Congo successfully lives, and even breeds in aquariums of 50-70 liters. Since it is bred for sale very actively, the fish has adapted to different conditions and aquariums. But, since it must be kept in a flock of six fish, it is recommended that the aquarium be 150-200 liters.

It is in the flock and open space, the congo will be able to fully reveal its beauty.

Water content is better to be soft, with a neutral or acidic reaction and a good flow. The light in the aquarium is muffled, it is better that there are floating plants on the surface.

It is important that the water in the aquarium is clean, regular changes are mandatory, as well as a good filter.

Recommended water parameters: temperature 23-28C, ph: 6.0-7.5, 4 – 18 dGH.

Ideally, it is better to create a biotope native to it – a dark soil, an abundance of plants, snags. At the bottom you can put the leaves of plants, give the water a brownish color, as in its native Congo River.

Congo males are larger, more brightly colored, they have larger fins. Females are small, painted much poorer, their belly is larger and rounder.

In general, to distinguish adult fish is quite simple.

The fish are peaceful and can be kept in a general or decorative aquarium with the same small and non-aggressive fish. You can not keep congo with aggressive fish in the general aquarium (barbs, cichlids).

Feeding aquarium fish must be correct: balanced, diverse. This fundamental rule is the key to successful keeping of any fish, be it guppies or astronotuses.

Article “How and how much to feed aquarium fish” talks in detail about this, it outlines the basic principles of the diet and feeding regime of fish.

In this article, we note the most important thing – feeding fish should not be monotonous; both dry and live food should be included in the diet. In addition, you need to take into account the gastronomic preferences of a particular fish and, depending on this, include in its diet ration either with the highest protein content or vice versa with vegetable ingredients.

Popular and popular feed for fish, of course, are dry food. For example, hourly and everywhere can be found on the aquarium shelves of food company “Tetra” – the leader of the Russian market, in fact, the range of feeds of this company is striking.

In the “gastronomic arsenal” of Tetra are included as individual feeds for a certain type of fish: for goldfish, for cichlids, for loricarids, guppies, labyrinths, arovan, discus, etc. Also, Tetra has developed specialized foods, for example, for enhancing color, fortified or for feeding fry.

Detailed information on all Tetra feeds, you can find on the official website of the company – here.

It should be noted that when buying any dry food, you should pay attention to the date of its production and shelf life, try not to buy food by weight, and also keep the food in a closed state – this will help avoid the development of pathogenic flora in it.

Tetra Congo (lat. Phenacogrammus interruptus) is a bright representative of the Kharatsin family.

Despite its small size, different contrasting appearance, it is difficult not to notice among the aquarium thickets. The luxurious body flickers with a fluorescent shimmer, and thin fins resemble a ladies’ fan.

Congo fish live in flocks, so they need a spacious aquarium for swimming. In captivity they grow up to 8 centimeters in length.

Natural habitat – the Congo River, which is located in the eponymous African country Congo (Zaire). It was first described by the French zoologist P. Boulanger in 1899.

Congo tetra described as a beautiful, calm, gregarious fish, leading an active lifestyle. Due to its unusual iridescent color, it was named “Blue Congo” and “Rainbow Congo”. In the Congo River, where these fish constantly live, the water is acidic and dark.

The diet – zooplankton, insects and plant debris.

Blue Congo can be called a large tetra, because an adult grows up to 6-8.5 cm in length. Live 3-5 years in good conditions. The adult fish looks like a rainbow, its color is replete with blue, orange, yellow, white and pink.

Females are smaller than males, their belly is rounded, males have longer fins. The fins of the fish are transparent, of a void shape with a white tint.

The dorsal fin is narrow, resembling a sail.

See how the rainbow tetra looks like.

The maintenance of such a pet is possible at home if you are an experienced aquarist. When you skillfully choose neighbors for the tetra, you can not worry about her safety.

Incorrect neighborhood can lead to adverse consequences.

For a full life in captivity will need both live and vegetable food. The rainbow tetra is an omnivorous fish, which simplifies its maintenance at home. Food can be purchased at a pet store: suitable flakes, small granules, which the fish can swallow.

Accepts live and frozen food. However, because of their timidity, they do not eat in plain sight, or do not have time to collect all the food, so carefully watch their meal.

Breeding rainbow tetra is possible if you are an aquarist with experience. In spawning, they are not so easy to multiply. For the brood, you will need the brightest pair of fish, which should be settled in separate containers for two weeks, feeding them with live food.

At the bottom of the spawning ground should lay out the separator mesh and plants to protect the eggs – like many tetras, Congo eat their offspring because of negligence.

The stimulation of reproduction is the acidity and softness of the aquatic environment, as well as the temperature rise to 26 degrees. In the spawning, the ready-made male actively cares for the female, chasing her until she agrees to spawning.

During the day the fish lays 100-300 large eggs. But on the first day, many of them die from a fungal disease, so it is recommended to add methylene blue to the water.

Parents need to sit out. After a week, fry appear, starter food for them – egg yolk and infusoria. Then add to the diet is recommended naupilii artemia.

They become sexually mature at the age of 10 months.
