If you in inheritance from kind friends or relatives got an aquarium with small fishes, anyway there will be an interest - how to distinguish a sex of fishes, including somik? To the experienced aquarian without effort will cope with this problem, and here the fan should penetrate into all subtleties of cultivation of fishes.
Instruction
1. For a start define a kind of the somik. There is a lot of them, and practically at each subspecies for sex determination certain external characteristics are considered: color, chest fin, upper fin, head, sizes of fish, etc.
2. Look at length of beams of chest fins of a somik of a dianema. As a rule, at males they are much longer. A body at females fuller and roundish, at males, on the contrary, - harmonious.
3. If at you in aquarium lives somik sparrow, look narrowly at the upper fin. At males it is pointed, and at females more roundish. Pay attention to a belly profile, at a mature female it is curved. Males more harmonious, than females.
4. At a somik of a koch, a golden somik, a somik meta, a somika speckled, a somika of a natterer, a leopard somik, a somik the pygmy determine sex by the same characteristics.
5. Pay attention to a color of somik torakatum. Young fishes and females have a white lower body, and adult males have a gray-violet color. On all body of a male dark stains "are scattered".
6. At a torakatum pay attention to the first beam of a chest fin. At males it is similar to a bone thorn and all is covered with small teeth. At females has the ordinary building.
7. Pay attention to the sizes of fishes. At all types of somik of a female much more stoutly and more males are also much more faintly painted.
8. If you have somiki-antsitrutosa, look at their heads. Males on the head have bone outgrowths in the form of small rozhek. Females have no such outgrowths.
9. And, at last, if on appearance gender of a somik did not manage to be assigned, get fish from an aquarium and look at a belly. At males-somikov the existence of a pronounced sexual hillock with a round opening is visible at once. At females an opening of an oval form, and the hillock is a little drowned and especially is not allocated.
