Lebiasin, or Pyrrhulin (Lebidsinidae)

They differ in a slender, very elongated body. Among the representatives of the seven genera, combined into four subfamilies, there are species with and without fat fins. They vary in lifestyle, but all come from South America; many are imported as aquarium fish and are therefore well known. True, representatives of the genera Lebiasina (Lebiasina) and Piabucina (Piabucina) are almost not brought. In contrast, “living pencils” (swim upside down) of the genera of Nannostomus and Nannobrycon are very common. It is easy to find the Harrison nannostomus (Nannostomus harrisoni) and the one-lane nanobricone (Nannobrycon unifasciatus), as well as the three-lane nanobricone ( Nannostomus trifasciatus): all three species barely reach a length of 5 cm. Nannostomus espei and N. marginatus grow up to 3.5 - 4 grow longer than 4 see, and therefore called dwarf. Pecilobricon (Nannobrycon eques) also does not exceed 5 cm. Lebiassins must be kept in aquariums, where at least along the edges the vegetation is dense. You cannot call these fish indefatigable swimmers, although they react very quickly under the perceived danger, in general, they hang with great pleasure between plants, so these magnificent fish are very convenient to consider. The bottom soil, as in their native ponds, should be kept in dark colors. The aquarium, which contains lebiassins, can be especially good if decorated with fancy rhizomes or snags. Fish willingly seek protection under these roots, offering them safe shelters. Best of all, fish feel in the water as soft as possible and filtered through peat. They live for a long time at a temperature of 24-26 ° C and when eating live food (insect larvae). Their reproduction is quite possible, and to start with a small vessel for 5-10 liters of water is enough. Males and females are usually easy to distinguish by the shape of the anal fin.

Nannostomus harrisoni

The same family includes different species of the genera kopein ( Soreina ) and copella ( Corell a ), as well as adjacent species of the genus pyrrhulin (Pyrrhulina), which, however, rarely come to us. Fishes of all three of these genera lack a fat fin, which is typical for most haracoid. Trout copein ( Copein a guttata), reaching 15 cm, is considered one of the largest species in the entire family. She lives in the central part of the Amazon basin, attracts attention with large scales and a rich blue color. Also interesting is its red speckled skin and the same color of the fin rim in the lower body. Trout kopein also requires a densely planted aquarium with as soft water as possible. Having reached 6 - 7 cm, she is already ready for spawning; spawns in a wide unpaved pubis, prepared by the male. The male also patrols the children's area, and parents do not devour the young, - a rarity for always gluttonous harakovidnyh. Young people should eat well: she has a great appetite, and she grows up very quickly.

At the copella Arnold ( Cope lla arnoldi), spawning takes place differently: the females spawn eggs not in the water, but on large sheets of plants located above a water mirror. At the same time, both producers (male - up to 8 cm, female - up to 6 cm), taking the characteristic “hug” pose, jump out of the water when eggs are spawned and fertilized. A couple needs to make several jumps, and for a start - trial (synchronization). The masonry is guarded by the male, which maintains moisture by spraying the tail with caviar. The appearance of fry occurs at a temperature of 28-30 ° C (avoid drafts !). The juveniles slips into the water, and now it requires the smallest live food. Other species of copella - C. nattereri, S. metae, C. compta, C. callolepis and C. vilmae - specialized trade not offered.
