Barbus Linear / Barbus Five Linear / Barbus Striped (Desmopuntius johorensis / Puntius johorensis) Duncker 1904.
Genus: Desmopuntius (Cottelaat, 2013)
Desmopuntius: from ancient Greek (desmotes), which means “prisoner / prisoner” in relation to the striped pattern of this species, and the generic name Puntius.
johorensis: named for the state of Johor, the southern peninsula of Malaysia, from which samples were collected.
Asia: from the Malay Peninsula to Borneo.
Originally from southern Thailand, peninsular Malaysia, Singapore, the islands of Sumatra (Indonesia) and Borneo (Malaysia, Indonesia and Brunei Darussalam).
In Thailand, it is known only in the province of Narathiwat, while in the peninsula Malaysia there are records from the states of Johor, Pahang, Terengganu, Selangor and Perak.
Sumatra is known from the provinces of Jambi (the Batang Hari River) and Riau (the Siak and Indragiri basins), as well as Borneo in the Malaysian state of Sarawak and in the Indonesian provinces of Central Kalimantan (the Mentaya River, Kalimantan Tenga River) and East Kalimantan (the Mahakam River, Kalimantan Timur ).
There are also a number of entries from Brunei Darussalam. In West Kalimantan (Kalimantan Barat) and possibly in southern Sarawak.
Most often it lives in peat bogs with stagnant water and the channels connected with them, in small forest streams, ditches and rivers with black water. Usually found at the bottom in shallow water.
Often in places with flooded grass or aquatic plants and dense coastal vegetation, at the bottom of which a large number of branches, fallen leaves, roots and trunks of trees accumulate.
The water itself is usually painted brown with humic acids released during the decomposition of organic substances. The content of dissolved minerals, as a rule, is insignificant, the pH is only 3.0 or 4.0.
The substrate is a mixture of sand and peat.
Fish with 5-6 strips on the body of individuals larger than 40 mm. The body is stretched, the profile of the back is curved, and the abdomen is flattened on the contrary.
The color is silver, sometimes with a golden shade, the back is olive, the abdomen is light silver. From the base of the gill covers are longitudinal dark stripes. The eyes are creamy yellow.
It has two pairs of whiskers.
The golden tail fin with black edging on the edge has a peculiar rounded and, as it were, notched form. The color of the high dorsal fin at the anterior margin is almost black, with a pale yellow strip adjacent to it.
The remaining fins are colorless.
Species feature is located on the throat longitudinal groove.
The maximum length is 12.0 cm, in aquariums it is usually 8 – 10 cm.
The fishes are quite peaceful, and even a little timid, but they cannot be kept with species in which the veil fins cause the barbs an irresistible desire to pluck them.
This is a schooling species by nature, therefore it is better to keep a group of fish alone is not recommended, in this case it begins to show aggression towards all aquarium inhabitants. Females should dominate in the flock.
They are very mobile, keep to the bottom, swim a little leaning forward.
Good neighbors will be Barbusy, Bozii and other relatively large carp species.
The basic dimensions are 100 * 40 cm or equivalent. A flock of these barbs will be comfortable in an aquarium from 150-200 liters.
When kept in a smaller capacity, males become aggressive towards females and can cripple and even kill them.
They like overgrown plants, while in need of open space for swimming, it is better if the substrate is soft, the lighting prefers scattered, muffled. You can also add aquatic plants that can survive in such conditions, such as the Thai fern, Java moss, various types of Cryptocorin.
Snags, stones and other decorations are necessary for shelter, but should not overload the aquarium.
Temperature: 23 – 27 ° С
pH: 5.0 – 7.0
Stiffness: up to 12 ° dH
Water is desirable peat with good filtration and aeration. Substitution is carried out weekly from 1/4 part.
In nature, it feeds on zooplankton and insect larvae along with algae, also worms and crustaceans.
In an aquarium, they are omnivorous, but it is best to regularly feed them with small live and frozen feeds (coretira, daphnia, bloodworm, pipe scythe, artemia), as well as dry flakes and pellets, some of which should include vegetable ingredients.
Adult males, as a rule, are slightly smaller, noticeably slimmer and have a more intense coloration than females.
The breeding process is quite simple. A separator grid and several bushes of a Thai fern or Javanese moss are placed in a 20-liter spawning tank.
Water parameters for spawning: 26-27 ° C, dH to 6, pH 5-6.5. The lighting is muffled.
Before you put these fish into an aquarium for breeding, you should separate the males and females a week before. Enhanced feeding with live food increases readiness for spawning.
Two males and a female are necessary for spawning. For some time, the fish get used to the new environment, and usually spawning occurs the next morning.
For several hours, the female spawns about 400 eggs, after which the producers settle out, as they eat caviar.
The water level decreases and after 24 – 36 hours very active larvae hatch, which are immediately able to swim.
Fry at the initial stage take Nauplii Artemia, Cyclops, Rotifers.
The initial color is beige and golden with dark spots. In 3-4 cm adolescents the spots turn pale, blur, connecting with each other and forming strips that are typical for adult fish.
By the age of 8-11 months it reaches sexual maturity.
The life span of most species of barbs is about 5 years.
It is one of three members of the genus Desmopuntius, together with D. gemellus and D. trifasciatus, although it can also be confused with the Striuntius lineatus. Conditions of detention, nutrition and breeding are all similar.
