ENCYCLOPEDIA of FISH FAMILIES

Lebiasin, or Pyrrulic (Lebidsinidae)

They have a slim, strongly elongated body. Among the representatives of seven genera, united in four subfamilies, there are species with and without fins. They differ in lifestyle, but they all come from South America; many are imported as aquarium fish and are therefore well known. True, representatives of the genera of Lebiasina (Lebiasina) and Piabusina (Piabucina) are almost not brought. And, on the contrary, “living pencils” (floating upside down) of genera by nannostom (Nannostomus) and nannobrikon (Nannobrycon) are very often found. It is easy to find the nanostome of Harrison (Nannostomus harrisoni) and the one- sided nanobricon (Nannobrycon unifasciatus), as well as the three-band nanobricon ( Nannostomus trifasciatus): all three species are barely 5 cm long. see, and therefore are called dwarf. Pecanobrikon (Nannobrycon eques) also does not happen more than 5 cm. Lebiasinovyh need to be maintained in aquariums, where at least at the edges of the vegetation is thick. These fish can not be called tireless swimmers, although at the perceived danger they react very quickly, in general, they hang with great pleasure between plants, so it is very convenient to consider these magnificent fish. Bottom soil, as in their native water bodies, should be kept in dark colors. The aquarium, where lebiasin plants are kept , is especially good if it is decorated with fancy rhizomes or snags. Fish eagerly seek protection under these roots, offering them safe shelter. Best of all, fish feel as soft and filtered through peat as possible. They live for a long time at a temperature of 24-26 ° C and when feeding on live food (insect larvae). Their reproduction is quite possible, and for a start, quite a small vessel of 5-10 liters of water. Males and females are usually easily distinguished by the shape of the anal fin.

Nannostomus harrisoni

This family includes various species of the kopein ( Sorein ) and Copella ( Sorell a ) genera , as well as adjacent species of the pyrruline (Pyrrhulina) genus , which, however, rarely come to us. In fish of all three of these genera, there is no fatty fin, which is typical for most harakovidnyh. Trout copein ( Copein a guttata), reaching 15 cm, is considered one of the largest species in the whole family. She lives in the central part of the Amazon, draws attention to the large scales and rich blue color. Also interesting is its red specks on scales and the same color of the fringe of the fins in the lower part of the body. Trout copein also requires a densely planted aquarium with possibly softer water. Reaching 6 - 7 cm, it is ready to spawn; spawn in wide, unpaved pubis prepared by a male. The male also patrols the children's area, and the parents do not devour the young, - a rarity for the always voracious haracid. Juveniles should eat well: she has a wonderful appetite, and she grows up very quickly.

At Copella Arnold ( Cope lla arnoldi) spawning is different: females spawn eggs not in the water, but on large sheets of plants located above the water mirror. At the same time, both producers (male - up to 8 cm, female - up to 6 cm), taking the characteristic “embrace” position, jump out of the water, when spawning and fertilization take place. The pair needs to make several jumps, and for the beginning - test ones (synchronization). The masonry is guarded by a male, which maintains moisture by spraying tail eggs. The appearance of fry occurs at a temperature of 28-30 ° C (to avoid drafts !). Juveniles slide into the water, and now it needs the smallest live food. Other types of copella - S. nattereri, S. metae, C. compta, c . callolepis and C. vilmae - specialized trade is not offered.
