Advice on cultivation

To the item of information:
The caviar of fishes, is usual ovule, which in most cases before fertilisation is outside of parent organism, that increases danger of its(her) destruction. Mammal send on a way of fertilisation inside a cavity of a body, for fishes the evolution "has chosen" some ways of preservation of caviar, and consequently also of all kind. The evolution has gone on the following ways: increase fruitfulness of fishes - > Occurrence of care about posterity - > Internal fertilisation and viviparous. The increase of fruitfulness, is one of the most simple ways to keep a kind. The given mechanism works very effectively in critical situations and for maximum kinds. Even mammal in crisis cases, at a low standard of living, adverse conditions of life more often give posterity. It is shown even and at the man, that there did not speak about a various level of culture. In the country, where a standard of living low, the birth rate raises, and absence / presence contraceptiv this do not prevent. Let's return to fish.. .. The highest fruitfulness at those fishes, that do not care of the posterity, lowest at viviparous of fishes, where destruction of posterity is minimal. As a consequence of high fruitfulness there are ways to apply her(it) more effectively to reduce loading on parent organism. It first of all reduction yolk in berry - that power making egg. The reduction yolk conducts to reduction of time embryonic of development, this period changes from 12 hours at fishes with high fruitfulness, up to 80 and more than day at less prolific fishes. The care of posterity allows to raise(increase) survival embryos and larvas by their protection against predators, of adverse conditions of environment(Wednesday) etc. Logical end it is the transition of this protection in a cavity of a body, that basically and represents internal fertilisation. Special copulation bodies at viviparous of fishes are a final means to avoid even losses sperm, not speaking about berry.

Advice on selection of fishes.
The correct selection of the manufacturers is necessary for is maximum - effective fertilisation. Main here, correct definition reproduction of age of fishes. At different kinds of fishes this term can make from a half-favour up to ten and more years. At the majority of the representatives living in an aquarium this age approximately is equal 1-2 years. Very important correct cultivation of the manufacturers. Feeding by a qualitative forage, observance of maximum satisfactory conditions обитания for the representatives of a concrete kind, absence anyone!!! Diseases on all extent of life of the manufacturer.

Advice on cultivation of fishes.
Specially for beginning aquarium person wishing to engage in cultivation aquariumen of fishes I want to advise to do the following, take the leaf of a paper and enter in him(it) the following actions:
1). Make sure, that the fishes are healthy. 2) . Ascertain, that they make a pair. 3) . Ascertain, that the fishes are well well-fed. 4) . Ascertain, that by him(it) is not close in spawning. 5) . Ascertain, that temperature of water is optimum. 6) . Ascertain, in high quality of water. 7) . Ascertain, in correctness of illumination. 8) . Ascertain, in cleanliness of an aquarium. 9) . Ascertain, that the plants in an aquarium suit fishes. 10) . Ascertain, that the fishes have reliable refuge.

Now each time, were going to choose a pair for cultivation, run by eyes this list once again to be convinced, that well remember each of them, and then at you it will not be simple more any efforts. Make sure, that the fishes are healthy. It is possible to expect good spawning only then, when the fishes are absolutely healthy. Doing(making) purchase in pet-shop, be convinced of that, as chosen by you рыбки and other fishes in an aquarium pet-shop are in the excellent(different) form. The best way of reception of healthy pair, is purchase of ten teenagers of the necessary kind and cultivation them up to the adult size. Though it also needs many patiences, but you will be sure that have not got already old individual, which have passed age of active duplication. Make sure, that they make a pair. In the majority cases you can not define(determine) a floor of fishes precisely enough, even because sometimes it and is impossible. However many kinds have sexual attributes, which at close(attentive) supervision can be distinguished. As a rule, fish-male surpasses fish-female in colouring and size плавников, and it(he) looks more gracefully. At transparent fishes fish-male have pointed swimming a bubble. At viviparous of kinds fishes the floor can be distinguished to a that attribute, that pelvic fin fish-male are lengthened and serve for introduction sperm in a body fish-female. Make sure, that the fishes are well well-fed. In the given context it means feeding(nursing) of fishes by the appropriate forage at their normal development. During this period fish-male and fish-female usually contain in different aquariums, and it allows fish quietly to ripen. It will be ideal to separate a conjugal pair, when at you the opportunity will appear to remain at date of houses, and to watch(keep up) its(her) behaviour since evening before assumed(prospective) spawning. If fish concern to a kind, eat up the caviar, at once make smb. change his seat them after spawning.

Make sure, that by him(it) is not close in spawningen. Do not think at all, that pair of large and active fishes will be spawninge in small spawningen. The fishes have "sixth" feeling, which prompts them, that in narrowness the posterity will not grow normally. Make sure, that temperature of water is optimum. Very much frequently incentive stimulus for spawning of many fishes is the increase of temperature of water. But it does not mean, that it is necessary to begin to use for heating an aquarium a boiler. However frequently attempts spawning come to an end by failure because of low temperature of water. Very much frequently small change of water and increase of temperature on a pair of degrees is an excellent(different) occasion for spawning. Make sure, of correctness of illumination. To see fishes in all magnificence much(many) aquarium person try more brightly to shine(cover) an aquarium. Shine(cover) his(its) lateral walls, that is more best to see the fishes. But know, it not always suits them. Make sure, of cleanliness of an aquarium. Careful cleaning of an aquarium, it only one of measures required for equipment of the tank under spawningen. Make sure, that the plants in an aquarium suit fishes. Almost in everyone spawningen necessarily there should be plants or their substitutes. Some fishes place berry among thin-leaf of plants, some attach them to a surface wide leafes, and some do(make) of plants of a jack or use slices of plants at a structure foame of jacks. Make sure, that the fishes have reliable refuge. A refuge for fishes serve not only plant. The stones or other firm objects at the bottom of aquarium, on which they to spawn caviar are not to a lesser degree necessary for many fishes. Many fishes use stones not only at spawning, but also are hidden among them minutes of danger. An excellent(different) prototype small caves is the old clay flower pot, it is desirable with several apertures on each side. But it is possible to combine cave from several large stones, only look after, that your structure was reliable enough.
