Blades – family Wedge Brute (Gasteropelecidae)
The family Gasteropeletsid includes three genera: Carnigiela (Carnegiella), Gasteropelekusov (Gasteropelecus) and Thoracoharax (Thoracocharax).
Fish of this family swim in the upper levels of the water.
Habitat: Wedge-Bruins hail from tropical regions of South America. There are on the territory from La Plata to Panama in small rivers, forest streams, quiet creeks with soft, clean, slightly acidic water.
Habitats are characterized by dense, low-hanging coastal vegetation, fallen branches, tree roots and fallen leaves at the bottom.
Description: into the family Gasteropelecidae combined fish with a very peculiar high body shape, strongly compressed on the sides. The line of the back is straight, and the abdomen is strongly curved in the form of a sharp arc, which served as the basis for the name.
The muscles of the shoulder girdle are concentrated in the chest.
A characteristic feature of Blades is winged elongated pectoral fins, with which the fish have the ability to “fly up” over water by about 80 cm and overcome the distance of 5 meters. Fat fin no, anal large, ventral on the contrary, very small, dorsal shifted back, large tail and sharply outlined.
Some species have a small mouth, others have a very small one.
Carnigiella marble (Carnegiella strigata)
Females are larger in size and full belly, males are brighter.
Spotted Blade (Gasteropelecus maculatus)
The size of some members of the Barrenbird is 2.5 and can reach 9 cm.
Arrangement and parameters of the aquarium: These species spend almost all of their time near the surface of the water, all members of the Baribouleen family are very peaceful fish with a rather timid temper, preferring to live in a flock of at least 5 individuals, better than a dozen – the fish becomes bolder and show more natural behavior. Ideal neighbors will be various types of peaceful catfish. Corridors and Loricarids, as well as Dwarf cichlids – various types of Apistograms.
An aquarium for them should be selected elongated (from 1 meter) with a large surface area of water. The presence of thickets of aquarium plants, it is desirable to cover most of the water surface with floating plants, it is possible to use branched snags, a dark substrate is desirable. When frightened, the fish are very jumpy, and the vegetation will prevent jumping.
For the same reason, the aquarium should be closed with a lid or cover glass. It is recommended to leave 10-15 cm between the water surface and the lid.
The lighting is weak or muffled.
Water parameters: 22-28 ° C, pH 6-7, dH 4-15.
Requires the installation of a powerful filter that provides moderate movement of water, in which the fish have a habit of hovering, aeration.
Sensitive to high levels of organic matter.
Nutrition: To feed the Barrenworms is necessary for various types of feed, both dry, live, and frozen, such as Artemia, Motyl, Coretra, Daphnia, Moina, Trubochnik, etc.
A lean diet consisting only of dry fodder shortens the lifespan of the fish. The specific structure of the mouth allows Blades to take food only near the surface, they do not sink to the bottom.
Reproduction: the clear breeding mechanism of the Barleyworms is not yet known. Several species have been successfully bred, including Carnegiella marthae, C. strigata strigata, C.strigata fasciata, Gasteropelecus maculatus and G. sternicla.
In almost all cases, the water used was acidic and very soft. Spawning occurs among floating plants.
It is desirable that the spawn should be elongated with a large number of floating and small-leaved plants. Be sure to create a moderate current of water and provide a muffled diffused light.
Aquarium should be covered with a lid, leaving 15-20 cm to the water.
Water parameters in the spawning aquarium: 25-28 ° С, pH 5.5-6.5, dH up to 5.
For spawning a group of fish is placed with a predominance of females. It begins in the evening or at dawn.
Females lay their eggs in the leaves of plants, mainly located near the surface. Some caviar may sink to the bottom.
Then either the producers are removed from the spawn, or the caviar is placed in a separate container, which is desirable to darken.
Incubation lasts from 24 to 48 hours. Fry are able to swim and take Nauplii Artemia for 3-5 days.
The main difference between Carnigiell and other representatives of the family of the Barrenbird is the absence of a fat fin and the structure of the teeth. Inhabit the streams of the upper and central parts of the Amazon basin and the waters of French Guiana.
It is difficult to tolerate transportation, so if the fish has white spots on the body, it means it needs to be quarantined before launching into the general aquarium.
