How to know a sex of fish

Not always it is simple to the beginning aquarian to orient in such colourful and unclear world of exotic small fishes. What to feed with how it is correct to contain and what to do if small fishes got sick or decided to get posterity? Of course, one of the main issues concerning the beginning fans how to distinguish males from the self-check. We master some knowledge of this business.

Instruction

1. Attentively peer at your wards. At some small fishes the sexual dimorphism is expressed very accurately therefore to distinguish boys from girls here will not be big work. However if you do not know, than ladies differ from gentlemen, external differences of small fishes, though to you will be noticeable, but will not give any information. At cultivation of the guppy by much it seems that it is not so simple to distinguish a male from a samochka. This delusion. Attentively look at an anal fin of a small fish. If it the boy pointed – before you if it is rounded – you consider the girl. On this sign, by the way, it is possible to define a sex of small fishes before their puberty when besides an anal fin the males practically differ in nothing from females. When small fishes grow up, the beautiful motley tail and a back fin becomes characteristic of boys. Samochki, on the contrary, remain imperceptible and gray, tail fins at them are much shorter also not such bright.

2. Pay attention to a shape of an anal fin. Not at all aquarium fishes the difference of floors is so notable. Relatives of the guppy a mollineziya have neither bright tails, nor specks. Both males and females possess uniform black coloring and are similar at each other, almost as like as two peas. Here to you in the help observation and a sharp-sighted eye. Mollineziya also differ on anal fins. At females they are rounded, and at males have the pronounced pikovidny form. Some types of mollineziya are at all owners of the extended and slightly bent anal fin so the boy on it can always be allocated from the general crowd.

3. Look at the size of small fishes. Often females are a little larger than males, and at some species of fish this difference rather notable. Of course, not one size you should not be guided as in pet-shops small fishes from a different dung often are on sale. For this reason it is necessary to pay attention and to other signs. At neon, for example, the strip on a paunch of a female has a small break, being slightly bent in the middle. Males are owners of absolutely direct back, and the strip on their body is parallel to the horizon. If you decided to separate males from females in pack danio – also pay attention to their size and arrangement of strips. Females are larger, and strips on a paunch at them blur a little. Males have more tightened figure and equal strips.
