How to pet and play with a Guppy fish ?


The guppy, also known as lebistes or fish million is one of the fish species most demanded by lovers of aquarium fluvial and one of the main reasons derives from the fact that this species is optimal to reproduce with great ease.

Knowing the species a little:

Its origin is of Trinidad, Barbados, Venezuela and north of Brazil mainly.
Their scientific names are: Poecilia reticulata, Lebistes poeciloides, Girardinus guppy and Lebistes reticulatus.

It is ideal for beginners, for being a prolific, peaceful, resistant fish.

Commonly known as: guppy, fish million or lebistes.

They are fish of hot water and it is recommended to raise them in temperatures between 22 ? C and 28 ? C (optimal: 25 ?)

They are fish tolerant to the conditions of the water and it is possible to raise them to room temperature (as long as it does not move far from the interval above)

1L is recommended. Or 1.5L. Of water per cm of adult fish
It is advisable to use filter tanks, so that oxygen helps to increase the average life.

Their food will mainly be on the surface of the tank and less from the bottom (as indicated by their mouth, positioned on the top of the head), although on more than one occasion you will see them in the background pecking some food rest (they are very sweet)

Their metabolism is very fast and it is recommended to feed them several times a day but in small quantities.

The food can be very varied, since in addition to the flakes for tropical fish, you can give them mosquito larvae, flakes, algae tablets and freeze-dried food, papillas made by hand (made with vegetables, meat, fish and some vitamin supplement).

On the physiognomy, the males are smaller than the females and they have a fin in its bottom in the form of tube called gonopodio that they use to reproduce.

Male guppys stand out for their beautiful colors, which vary from greens, blues, reds and even brindles, while females are generally olive colored and only show color on their dorsal fin and tail.

There are many variants: veil tail, round, sword, flag, lyre, triangular, etc.

The life expectancy of the species is approximately one year.

They can be kept in aquariums of any size, preferably planted with as much vegetation as possible.
Substrate can be placed normal sand or fine gravel.

This species is susceptible to rotting of fins, secondary bacterial and mold infections.

Aspects to consider for reproduction, birth and subsequent breeding of guppy:

This species reaches sexual maturity three months after birth.
Guppy males are very sexually active and for this reason you will see that they are continually engaged in chasing females.

During sex, the male is placed near the female in the form of an “S” and uses gonopodium to shoot packages of sperm to female.

One important reason to consider why this species reproduces quickly is because even when females are fertilized and give birth to fry, they can retain part of the males’ sperm to self-fertilize for a season. Many times this makes it difficult to determine who the father is.

The guppies are ovoviviparous, that is to say that the females develop the eggs in their interior until they mature and they light the fry.

When the female becomes pregnant, an increase in size may be observed during gestation, in addition to a characteristic black spot on the back.

The spot that appears on the females will increase in size as the time of delivery approaches. Also, when the time of delivery is approaching, You will notice how the female changes her physiognomy and has a “round pansite”, it becomes somewhat “square”, a phenomenon that is due to the fact that the amount of fry within her have “deformed” her belly, but it will return to normal once the fry are born. Sometimes even small black spots can be seen inside the spot, which are the eyes of the fry.

The birth of the fry usually does not occur in a single moment, but they are born little by little, even the birth can last several days. (Maximum 3)

The fry at birth, initially fall to the bottom in the form of “ball” to immediately afterwards swim.

The number of offspring depends on the size of the mother and other factors.

The layers can range from 3 fry to a maximum of 50.

The swelling of the female pansite and the black spot disappears after lighting all the fry, otherwise it means that it has not yet finished and that more fry are on the way.

Fry do not actively swim shortly after birth, so you will notice that they hide under aquatic plants or places far away and difficult to access, so that they are not eaten.

After childbirth it is advisable to remove the females that otherwise will continue to be harassed by the males.

Feed the fry with: freshly hatched artemia, zooplankton, prepared in crushed flakes, boiled egg yolk, parboiled chicken liver and / or grindal worm. Fry are sensitive to ammonia concentrations.
