ENCYCLOPEDIA OF FISH FAMILIES

Lebiaxin, or Pyrrhic (Lebidsinidae)

They differ in a slender, strongly elongated body. Among the representatives of seven genera, united in four subfamilies, there are species with fat fins and without them. They differ 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 piabusin (Piabucina) are almost not brought. And, on the contrary, "live pencils" (floating up the head) of the generic nannostom (Nannostomus) and nanbrikon (Nannobrycon) are very common. It is easy to find the nannostomus harrisoni nannostom and Nannobrycon unifasciatus , as well as the three-pronged nanbrikon ( Nannostomus trifasciatus): all three species barely reach a length of 5 cm. Nannostomus espei and N. marginatus grow no longer than 3.5-4 Cm, and therefore are called dwarfish. Pecilobrikon (Nannobrycon eques) also does not happen more than 5 cm. Lebiasin should be kept in aquariums, where at least along the edges the vegetation is dense. These fish can not be called indefatigable swimmers, Although at the alleged risk they react very quickly, And in general they are with great pleasure hanging between plants, so that these magnificent fish are very convenient to consider. The bottom soil, as in their native reservoirs, should be kept in dark tones. The aquarium, where I contain lebiasin, is especially good if decorated with bizarre rhizomes or snags. Fish are eager to seek protection under these roots, offering them safe hiding places. L uchshe 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 fed with live food (larvae of insects). Reproduction of them is quite possible, and to start a sufficiently small vessel for 5-10 liters of water. Males and females are usually easily distinguished by the shape of the anal fin.

Nannostomus harrisoni

To this family belong different kinds of genera kopeina ( Copina ) and Copella ( Copelia ), as well as adjacent species of the genus pyrrulina (Pyrrhulina), which, however, rarely come to us. In fish of all three of these genera, there is no fat fin, which is typical for Most haraakovidnyh. The trout capeine ( 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 basin, attracts attention with large scales and a rich blue coloration. Interesting is also its red prick on the scales and the same color of the fins in the lower part of the body. Trout kopeine also requires a densely planted aquarium with possibly softer water. Having reached 6 - 7 cm, it is already ready to spawn; Caviar sweeps out in a wide ground pub, prepared by the male. The male also patrols the children's area, and parents do not devour juveniles, - a great rarity for always voracious haraakovidnyh. Young people should eat well: she has a wonderful appetite, and she grows up very quickly.

Cope lla arnoldi

In the cope of Arnold ( Cope lla arnoldi) spawning takes place differently: females sweep caviar not in 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 a characteristic "embrace" pose, jump out of the water when eggs are mowed and fertilized. The pair needs to make several jumps, and to start - trial (synchronization). The masonry is guarded by a male, which maintains moisture, sprinkling the tail with its tail. The appearance of fry occurs at a temperature of 28-30 ° C (do not allow drafts !). The young slides into the water, and now she needs the smallest live food. Other types of copelas are C. nattereri, S .. Metae, C. compta, C. Callolepis and C. Vilmae - no specialized trade is offered.
