Dario dario (Dario dario) – description, content, breeding

Dario Dario (Dario dario / Scarlet Badis) Hamilton, 1822

Other names: Badis Scarlet, Badis Red, Badis Dario.

Squad: Perciformes (Perciformes)
Family: Badiae

It appears to be limited to a system of tributaries flowing into the Brahmaputra River in parts of the regions of West Bengal and Assam, India, although it can also reach Bhutan.

As a rule, it lives in shallow water up to 1 meter, transparent streams with sand or gravel on the bottom and dense thickets of coastal and / or aquatic vegetation. In one place of the assembly of macrophytes * there were plants of the genus Hygrophil, Limnophil, Otel, Rotal and Vallisneria.

* Macrophytes are the habitat of the most important phytophilic fauna in terms of feed, a substrate for spawning many fish, a shelter and feeding place for their young, indicators of water quality.

This fish is very small, the body of a male is red with 7 transverse rows of shimmering turquoise stripes. All fins are red with a blue outline.

Males and females differ when they reach puberty. The females are silver-gray with transparent fins with obscure vertical lines, smaller, and they have a more rounded body. Males have elongated ventral fins of red color with a shimmering blue stripe.

The iris is golden to light amber.

However, the distinction between males and females when making a purchase at a pet store is much more difficult to do than described here. Because the fish are often still young and have the same color and shape of the fins.

In addition, many males, especially when they have the lowest priority in the group, have a uniform gray color.

Maximum Standard length 13 mm (female) – 20 mm (male).

A pair or one male with several females can be placed in an aquarium with basic dimensions of 45 * 30 cm or more.

Well-kept and well-structured aquarium with plenty of shelters. A soft substrate is preferred, although fine gravel will also be suitable, and ideal plants include Cryptocorins or those that can be attached to the decor, such as the Thai Fern / Microseorium, Anubias or various types of Yavan Moss.

The latter is particularly useful since it is also an excellent spawning substrate, and branches / snags, floating plants and dry leaves can also be used to recreate the natural biotope.

Temperature: 18 – 26 ° C
pH: 6.5 – 8.5
Stiffness: 3 – 15 ° DH

Dario Dario desirable muffled light and very clean water. They are sensitive to water quality.

Partial water changes should be made regularly.

Slowly moving with a passive character, they are easily frightened, more aggressive neighbors in the aquarium easily push them into the background during feeding. It is better to be alone or with small pelagic ** species.

Rival males can be very aggressive towards each other, especially in confined spaces. For small aquariums, it is desirable to acquire only one pair or one male and several females, and in a larger one, groups can coexist, provided there is space and shelters for each male, so that he can establish his own territory.

Well-planned placement of caves and grottoes can help in this regard; Resist the temptation to group all available breeding grounds in one area, for example. If you intend to keep them in community with other fish, then the neighbors in the aquarium should be carefully selected.

** Sang fish species – inhabited in the pelagial – in the thickness or on the surface of the water.

Dario species are micro-predators feeding on small aquatic crustaceans, worms, insect larvae, and other zooplankton. In the aquarium, they should be offered small live or frozen food, such as Nauplii Artemia, Daphnia, Grindal.

Accept and dry high-quality feed.

Badis tend to develop problems with obesity and become more susceptible to diseases when monotonous feeding Mityl or Tubing, so they should be excluded from the daily diet.

This species is very easily distinguished, but often they trade only in males.

Females are smaller, less bright, almost gray (they do not have red or blue pigmentation) and have a noticeably shorter and rounded body profile. In addition, males develop elongated ventral, dorsal and anal fins when they mature.

Dario Dario form temporary pairs, forming temporary relations. It is better to remove other fish if you want to raise a good number of fry, although few can survive in a well-equipped aquarium.

Either one pair or a group of adult fish can be used, and when using several males it is imperative to provide for each place so that it can form an area of ​​about 30 cm2 each. One male usually becomes dominant, the rest will not participate in breeding.

Water parameters should be within the values ​​suggested above and stimulated by increasing feedings with live and frozen feeds. When they are ready for breeding, the males begin to develop their territories and demonstrate mating behavior along with intense coloring.

This may be delayed for several days, the female is then driven off, and then a minute later the courtship begins again. The male makes a non-aggressive rapprochement with the female, apparently “invites” her to the center of its territory, and if she is ready for spawning, she will follow him.

The spawning itself lasts for only a few seconds, the roe is deposited randomly on the underside of a solid surface, such as a leaf of a plant. After spawning, the female quickly disappears and the male takes full responsibility for the territory.

If you want to increase the number of fry, now is the time, remove the carrier with caviar in a container containing water from the spawning aquarium or adult fish, as the fry will immediately be hunted as soon as they hatch.

The incubation period is 2-3 days, after which the fry may take up to a week to completely absorb the contents of the yolk sac. They are really very small and they will need a diet from ciliates, after about 14 days they begin to take a microworm, Nauplii Artemia and the like.

Dario Dario Dario dario / Scarlet Badis has a lifespan of 3-5 years.

This species has become one of the most popular Badia in aquariums, and is an ideal choice for nano aquariums, as it is one of the smallest known perch-like fish.

Dario currently contains five species, of which four are considered miniature species, as they do not exceed 26 mm in standard length.

It is easiest to distinguish Dario from Badis by the small size of adult individuals of the species, mostly red, the more elongated first rays of the dorsal and pectoral fins in males, with straight edges (against rounded) tail fin, the absence of a visible lateral line and less caring behavior of parents.
