Rasbora heteromorph, she klinopyatnisty – small and beautiful fish

Razbor heteromorph (latin. Trigonostigma heteromorpha) or as it is also called rasbora klinopyatnistaya (wedge-shaped) is a very common and popular aquarium fish, which you will find in almost any pet store. Rasbora fish is small and peaceful, which perfectly gets on with other peaceful species.

There are also several variations – albinos, gold, etc.

An unpretentious rassom wedge-shaped fish, which, thanks to its popularity, is extremely common. Although she prefers soft and sour water, her popularity has made it possible to adapt to different parameters of water.

Rasbor aquarium fish is one of the most unpretentious and adapts to different conditions. A small aquarium is enough to hold, and 40 liters is enough for a flock. It is better to keep them in water with a pH of 6-7.8 and medium hardness up to 15 ° dH. However, it is well tolerated by other parameters.

But for breeding have to try.

Water filtration is desirable, but not very powerful filters can be used as long as the water is clean. Be sure to weekly replace up to 25% of water for fresh.
The aquarium in which you are going to plant fish should be densely planted with plants with open swimming areas. They prefer species that are found in nature in habitats, such as cryptocoryne or aponoheton, but other species will do.
Dense thickets and driftwood will help the wedge-shaped rasboram to take cover in the shadows and get away from the stress caused by the relocation. It is also a good idea to let floating plants float to the surface of the water;
It is important to keep the fish a flock, because in nature they live that way. Minimum quantity – from 7 pieces.

Aquarium fish rassom: description, content, reproduction and reviews

This type of ornamental fish is very popular with novice aquarists. Its popularity can be easily explained.

Rasbory – fish, the content of which is very simple. They are unpretentious in care and easily make friends with other inhabitants.

Aquarium fish rasbory happy to share with guppies, tetras, gourami, danios, shark barbs and others. Even a child can take care of them!

The described species is distinguished by its mobility and liveliness. These fish prefer to dwell in the flock, so in the aquarium it is best to keep them at least 10-15 individuals.

In the length of the fish debacle reaches 4-10 centimeters. Most of them have an elongated body and slightly flattened laterally.

Some representatives have a short and high body.

Rasbora – a fish that, in nature, feeds on insect larvae and plankton. But in the home content, it is absolutely unpretentious to the feed.

By the way, in the aquarium there must be plants that in some places flow into real thickets, where shy babies could hide.

This species was discovered relatively recently in Myanmar – it is also called rasping fireworks or margaritat. Among aquarists this species quickly gained popularity.

Small fish of the galaxy is very peaceful and coexists fairly well with other non-aggressive types of aquarium fish. This baby lives two years. It feeds mainly small live food: daphnia, grindaly and nematodes.

They can eat and cut moth. Use of high quality dry food is possible.

In the length of the settlement of the galaxy – only 2-3 centimeters. However, their bright color more than compensates for the small size.

The color of the females is much more modest than that of the males: they are dull, have transparent fins, which have red markings at the base. The male is a holder of fins with a bright red stripe, and is also painted laterally in a gray-black background with bright patches.

Since the pickup is a very small fish, it is worth keeping a flock of 28-32 pieces.

Content and habits, they are somewhat reminiscent of guppies. The displacement of the aquarium does not matter: it can be either four liters or five hundred.

The optimum water temperature for these babies varies from 25 to 28 ° C.

This species is also called wedge-shaped rasboroi or rasboroi heteromorph. Under natural conditions, it lives in Malaysia, Indonesia and Thailand.

It can also be found off the coast of the Java Peninsula.

This fish was brought to Russia in 1991, and they started actively breeding in the late 50s of the last century.

The overall body color of the cuneopus rasbor golden-silver or gold. Body length from 4 to 4.5 cm.

The tail fin is transparent and has a deep recess. Color – yellowish, has a red border.

On the body she has a triangular wedge of purple color, which begins in the middle of the body and ends closer to the caudal fin.

With this spot males are distinguished from females. Thus, in the male it has sharp and sharp angles, ending on the abdomen near the anal fin, whereas in females it gradually becomes rounded, not reaching the lower part of the abdomen.

For these fish water is defended for at least three to four days. The most optimal temperature is 23-25 ​​° C.

In order to bring the aquarium conditions as close as possible to the natural habitat, boiled peat can be put under the ground, which consists of sand, pebbles or small gravel. And some parts of the aquarium is best densely planted with vegetation.

The diet of these rasbor mainly consists of live food, for example, bloodworms, daphnia, cyclops, atemia or enhitreya. You can make a diet of special granular dry food, but still it is better to prefer live.

Wedge variety rasbor will look great in an aquarium, the background of which is quite dark.

Corpuscle fish is small, even miniature, not more than four centimeters in length. It is tall, longish, flattened laterally.

At one end of the body is a mouth, on the other – the tail of the two blades.

Coloring heteromorphs bright enough and beautiful. The general background of the body can be copper, pinkish, almost red, and also olive-green with a silver belly.

Picture. On both sides there are large triangular spots of black or dark blue with a steel shade, the shape similar to a wedge.

Hence the name rasbora – wedge.

Tail and fin on the back bright crimson, other pale pink.

Interestingly, the shape and size of dark spots can distinguish the sex of the fish. If the spot is short (does not reach the abdomen) and its lower corner is rounded, then we have a female. She also has a fuller belly.

If the spot is long (stretches to the anal fin) and acute, then this is a male. Male individuals are slimmer than their ladies.

These amazing creatures are very mobile and active. They prefer to be in the upper and middle layers of water.

Keep them better flocks of at least 10 pieces. In this case, you will reduce the level of stress in the fish and be able to more clearly see the characteristics of their behavior.

School content also brightens the color heteromorph. Especially males, which are in a large flock of females, flourish.

Rasbor can be kept in common aquariums, having thickets from plants and floating algae. They have a very peaceful and livable nature.

Neighbors of these fish should be selected approximately the same in size and non-aggressive.

For example, it can be neon, erythrosonus, pretella or other types of tetras.

Large predators such as kissing gourami, black pacu, piranha are absolutely not suitable for sharing with them. They perceive rasbor only as food.

In terms of food, these fish are picky. In nature, they eat various insects, worms, larvae and zooplankton.

In an aquarium, they can be given all kinds of food: live, frozen, dry.

A fine bloodworm, crustaceans, a tubule, artemia will do well. The main thing is that the food particles should not be large, as the fish simply cannot capture them.

Scalded semolina, oatmeal and crumbled white bread can be used as an additional top dressing.

This type of ornamental fish is very popular among aquarium lovers. Such popularity rasborov received because of its simplicity, a variety of shapes and colorings. They feel great in the aquarium, unpretentious to feed.

Despite the possible difficulties with the habitat, they are always distinguished by increased activity and adapt well in captivity.

The most widespread species in nature received in Southeast Asia, the Philippines, Indonesia and India. They belong to the carp family. However, the climate most suitable for fish is the climate of Thailand.

In captivity, aquarium fish rasborah – a small fish the size of two centimeters. Among them are “giants” up to seven centimeters. The fish quickly adapts to the new habitat, has a good survival rate, therefore it is often recommended to beginner aquarists.

However, it is worth remembering that the fish should be kept in small flocks, 6-8 each. This practice is not only useful for breeding.

A small flock of bright and brilliant aquarium fish looks very nice in the aquarium.

Among the varieties stands out wedge sprouting. It differs spot on the side, which resembles a triangle, black with blue tint. They are also characterized by large eyes, which do not correspond to the size of the body.

Contains a wedge-shaped assembly in ordinary aquariums, the capacity of which is not less than fifty liters. Succinated water can serve as a favorable environment for rasbor, in which it is desirable to add peat extract.

Do not plant an aquarium with lots of algae. A sufficient amount of free space is necessary for the carp fish of the family, since its activity must be manifested in the free territory.

Otherwise, cuspidata rasboru can quickly get sick.

On how the content is rasbor, depends on their lifespan and reproduction. As already mentioned, the fish are unpretentious, so you can feed them with any food for fish.

However, if you do not add live food and oxygen, reproduction rasbor may stop or be completely absent.

Subject to certain subtleties, breeding rasbor simple.

In the last decade, a real boom has occurred in aquarism associated with the emergence of miniature fish and shrimp for nano-aquariums. In any market, you can meet a variety of small fish, and even from the abundance of shrimp eyes run.

Manufacturers even began to produce special equipment for nano-aquariums, so they became popular.
Among the fish for nano-aquariums, fish of the genus Boraras (Boraras) or micro-assemblies stand out separately, as long as six species are counted. Courteous that they are very beautiful, livable, unpretentious, besides very small, it is clear the reason for their popularity. But, as is the case with most new fish, a lot of conflicting information was born on the Internet about the content.

Let’s try to figure out where the truth is, and where not.

At the moment, there are six species of these fish, and it is better to describe them in millimeters, and not in centimeters. It:

  • Rasbor pygmy (Boraras maculatus) is the largest, as much as 22 mm
  • crumbling micro or micro (Boraras micros) – 13 mm
  • Rasbor firefly (Boraras urophthalmoides) – 16 mm
  • measure or red (Boraras merah) – 16 mm
  • Rasbor briggits (Boraras brigittae) – 18 mm
  • Rasbor nevus (Boraras naevus) – 12 mm

One or two other types occasionally appear on sale, but they do not even have their own name, and are sold under different names. Note that for the Russian-speaking aquaristics, some species are also little known and the names given in the future can still be distinguished from the actual ones.

Why, there they are called either rass collections, then micro dissections … we will call them anyway.

Although all these fish have become popular thanks to nano-aquariums, it is better to keep them in larger banks, 50-70 liter. But, in a large and noticeable flock that looks charming against the background of dark soil, snags, and cryptocoryne or Anubias bushes.

In addition, the presence in the water of snags or fallen leaves of the oak is a key point in breeding.
In nature, rasboru are most often found in reservoirs with weak current or standing water, so it is better to create the same conditions in an aquarium. For example, a small internal filter will create a current at the surface of the water, but in the thickness it will be almost imperceptible.

Water parameters are important if you are dealing with fish caught in nature. Most of them come from places where the pH is only 4.0, and the water is very soft.

Accordingly, if they are transplanted into water with hard water, then it is a great stress.

Wild Boraras should at first be contained in water, which in terms of parameters will be as close as possible to that in nature. You must use at least 50% of the water from osmosis, plus peat. With the help of small, regular water changes, rasbora adapt to new conditions within a couple of months.

They get used to quite hard, alkaline water and live quite well, although not all species can be diluted in such water.
In general, rasbor adapt and live in water with a pH of 6.8–7.2 and medium hardness, no problem. Especially if you buy fish that are bred in your area, and not brought from nature.

If you are thinking about a nano-aquarium and want bright fish, interesting in behavior, easy to care for, then stop at one of the types of Boraras. If your aquarium is more spacious, then even better. There you can get a whole colony of small, bright, active fish.

Let them be only one and a half centimeters long.

Rasbor Espay belongs to the carp family and is often referred to as the triganostigma Espay. This is a very small, high-spirited and unpretentious fish – a great choice for beginning aquarists.

Rasbora espey is a very bright fish; her body is low, relatively short, slightly compressed from the sides. This nano-pet has a very variegated orange-red color. Fish seem to glow from the inside (which is especially noticeable in males).

The back of the aquarium inhabitant is olive-green, and the abdominal part is silvery. On the back half of the body there is a blue-black triangle, similar to a wedge, – in males this spot has sharper angles than in females.

The dorsal fin in boys is reddish, with a black dash on the tip, and in the females – a more delicate pink color. Anal, pectoral and ventral fins – transparent yellowish.

The tail fin is yellowish, along it red rays extend to the body itself. These aquarium inhabitants grow up to 2.5 cm.

Rasbory – the fish are surprisingly peaceful and friendly, which allows them to be considered ideal neighbors for other residents of the aquarium. These nano-fish get along with almost all popular species among aquarists. They prefer to keep in small families of 5-10 individuals.

In this case, the males, competing among themselves, will show the most vivid color in the struggle for the attention of females.

Rasbora unpretentious, so they have no special requirements for the aquatic environment and its chemical composition. In addition, the fish live fine in small aquariums.

As for the temperature, it can vary from 23ºС to 28ºС.

Like a pickup – a very shy little fish, it needs vegetation in which it could easily hide and calm down at the slightest danger. As the filter is usually used floating flora.

Well, and the decorations in the form of bamboo branches and snags will perfectly complement the existing picture, which will allow the fish to feel almost in their natural habitat.

Another distinctive feature of the fish is their exceptional pickiness. You can feed your pets with dry or frozen food – both vegetable and animal origin.

With proper observance of all the recommendations on the content of the analysis, Espea is always ready to please the owner with cheerfulness and even brighter and variegated colors of her color.

Rasbora has gained popularity with aquarists for a reason. This fish is distinguished by a lively disposition, activity and ability to adapt to almost any conditions.

Unusual color variations rasbor allow you to decorate the whole water kingdom with one flock.

In addition, breeding rasbor is not difficult even for inexperienced owners of aquariums: these fish easily breed in a small amount of water, and their fry develop very quickly. All this makes representatives of the carp family a favorite among fish breeders.

One of the most common varieties is wedge shaped wedge. It is also called clinopyatnist or heteromorph. The body of this fish is wider than the rest of the rasbor, and from the middle to the tail there is an elongated wedge-shaped spot.

Hetemorphs grow to four centimeters. The main color of the adult individual is pinkish with silver tints.

Bright red stripes are distinguishable on the dorsal fin and tail of the fish.

For beginners aquarists wedge-shaped rasbora – a great option. A flock of such fish can live in peace in a small aquarium of thirty liters and feel comfortable there.

Water temperature should be high – up to 28 ° C, hardness – not more than 60, acidity – about 6 pH.
