Good day! Today we will look at an aquarium fish from the carp family, called the Barbus Linear. In nature, this fish lives in the equatorial reservoirs of the island of Sumatra and Klimantan, where year-round air temperature stays around 24 degrees, and the annual rainfall varies from 2000 mm to 5000 mm depending on the area.
For the first time in Europe, the four-line barbus fell in 1935, 20 years later he reached the Soviet Union.
The four-line barb grows to 10 centimeters in length. His body is slightly lengthened, his back arched.
The fish is painted in golden yellow color. Four continuous stripes of black and blue are running along the body. The body shape of the four-line barb slightly resembles the shape of a zebrafish body.
The fins of a hydrobiont are colorless and transparent. The tail is rounded and it is colored in golden yellow color.
The dorsal fin is black with a yellow border. All other fins are colorless and transparent.
The iris is creamy yellow, the mouth is brown and the lower lip is pale blue. Male from female can be distinguished by smaller dimensions and brighter coloration.
The color of the males has a reddish tinge, and the dorsal fin has a pointed shape with a pinkish tinge. The dimensions of the females are somewhat larger than those of the males, and besides, their backs are more arched.
The belly is round and the color is not so saturated.
Linear barb is a schooling and peaceful aquarium fish, which it is desirable to keep a flock in the amount of 8 – 10 pieces. This representative of the carp family perfectly gets on with other medium-sized peaceful neighbors (red neons, cherry barbs, Velifer mollies, swordtails).
But if you decide to keep this barb in one quantity, it can become quite aggressive and very shy.
The only condition of the schooling content of this barb is that the number of females in the pack must be greater than the males. Like the Sumatran congener, the linear barb gets along poorly with veil fish, as he is not averse to nibbling on their fins.
A flock of young barbs is quite active and never keeps in one place in the aquarium. They prefer to constantly swim in the thickets of plants.
Considering this moment, make sure that there is enough grass in your bank where the fish can find shelter.
The four-line barb is kept mainly in the lower layer of water. The conditions of the fish unpretentious, eats any type of food. The fish can perfectly eat both ice cream and live food, and dry, and vegetable food.
For a more comfortable maintenance of the fish, you will have to get a fairly spacious aquarium from 100 – 150 liters. The fact is that the fish has a slightly cocky character, and in small capacities of the male can beat the females.
If there are elements of decor in the aquarium (stones, snags, grottoes and other things), then they should not limit the maneuvering space for the fish.
The lighting in the aquarium should be moderate, and at the bottom should be dark ground, which will emphasize the beauty of this fish. Aquarium water is preferably slightly peaty, it should be well blown out and filtered. The temperature of the water should be within 22 – 26 degrees, the hardness is not more than 22 degrees and the acidity is about pH 7
Once a week it is necessary to do a water change in the amount of 1/3 of the volume.
The linear barb reaches sexual maturity by 10–11 months of life. To breed this fish, it is necessary to select a couple of males and one female for spawning.
Before spawning, the producers are kept apart for a week in separate containers and are abundantly fed with various foods. After a week of feeding, producers should be placed in the spawning tank, in which the water temperature should be 26 – 28 degrees, the active response of the medium is 6.5 – 7 pH, and the hardness is within 6.0 – 6.5 °.
During one spawning, the female lays from 350 to 500 small eggs that are glued to aquarium plants. The incubation period for eggs takes up to 36 hours, after which small and very mobile fry appear on the light. Body color in young golden-beige with dark spots.
When the fry reach 3 centimeters in length, dark specks begin to fade and smudge over time. Eventually they will turn into jumpers that form dark stripes on the body.
As young animals mature, their body color gradually becomes the same as that of their parents. Starter feed for fry: rotifers and cyclops nauplii.
