Poecilia Reticulata a Wonderful fish

If you are an aquarium lover, it’s possible that you have heard about Poecilia Reticulata.

In any case Poecilia R. is the latin name of our friends guppies

Poecilia Reticulata is probably one of the most well known and popular freshwater fish that is alive today in the whole world.

That’s why you can visit one,two or three aquarium shops and pocilias everytime stay there!

The name we are using is its species name but it is more commonly known as the guppy which I think it’s safe to say most people have heard of if they have ever looked into fish keeping of some sort.


The poecilia reticulata fish belongs to the poeciliida family which consist of live-bearing fish which means that they don’t lay eggs like all other fish do, these keep the eggs inside of them and allow them to grow to full maturity and once that stage has been reached they give birth to live young.


It was in 1866 went Poecilia Reticulata were first discovered in Trinidad by a man named Robert Lechmere Guppy which is where the common name first originated from out of honor for finding this fish.

Although in recent times the guppy has been taken and introduced in to every country on the planet bar Antarctica, majority of this was done my human error or simple mistakes but guppies have also purposely been introduced as a way of dealing with mosquito’s  by feeding on the larvae

There have been mixed views on this matter to weather it works or not but many people have said that if you are not feeding the fish yourself the do eat the larvae and control the pests as they would do in the wild.


The guppy, also known as million fish, is a minuscule, prismatic species of tropical freshwater fish.

Poecilia R. has been found living natively in a whole host of countries including Barbados, Guyana, Brazil, Tobago and the USA

Guppies are naturally present in estuary and bond in South American rivers.

They come in all possible colours, sizes, and tail sizes also in the wild.

According to the research, guppies can survive temperatures of fifty-five degrees Fahrenheit, but should ideally be stored in water between 70-80 degrees Fahrenheit.

A small amount of salt in your aquarium water can help reduce stress for the fish, but maintaining mineral intake is more important.


The term habitat is used to describe a particular area in which a specific animal lives in the environment.

Many animals are adapted to certain conditions that can only be found in natural habitats.

The natural distribution areas are rivers and clean mountain streams, in which there are few aquatic plants, turbulent waters and some spot where water flow slowly, typically at shoreside.

We can find guppies in stream located in altitude but also in flat rivers.

Poecilia Reticulata tolerates a variety of temperature, including average 40 to 60 per cent seawater, but is usually found in coastal freshwater rivers.

In non-native areas, guppies are often the only species in heavily polluted waters.

As said before,In the wild, guppies feed insects, crustaceans and insect larvae.

The taste of mosquito larvae is one of the reasons why this fish is used to combat mosquito populations with malaria in lakes and ponds in Asian countries.


The recommended ph level of the aquarium water must be between 6.8 and 7.6. the best range is between 7.0 and 7.2.

Kits to check and modify the pH scale level of the aquarium water are out there in most pet stores. 

Taking time to check pH scale levels is a very important part of maintaining a healthy tank for your guppies.

In nature Poecilia R. live in very different waters.

But, in a general way, they prefer water with high value GH, also known as Hard Waters.


Female guppies have a different lenght compared to male, “Miss guppies” are larger than males.

they have soft and dull coloured bodies with brighter colours enhancing the tail.

Male guppies are bright coloured, and also the pattern and color possibilities are endless.

The guppy colors are due to tiny spots on the skin called melanophores.

The amount and site of the melanophores determines the variable patterns and colours of the Poecilia R. additionally to color and size variations

Guppies are one of the smallest of an endless variety of fish in a large family.

Male anal fin , called Gonopodium, turns into reproductive organs, and female guppies and Gambusia have “pregnancy spots”


Gambusia and guppies are both members of the genus Poecilia and have as Molly and Platy.

Gambusia reach 1 1/2 inches in length and are sturdy but compressed.

They are ocher to olive above, pale yellow below, and the scales have dark spots on the edges

Male can have blue glitter on the side, and the female is taller .

Guppy males are 1 1/4 inches in length, and females are 2 1/4 inches in length.

The wild guppy has irregular black spots or spots with shimmering red, blue, and green colors on the sides.

Gambusia, also called Mosquito fish, are a little less attractive and do not like to live with other fish.

As aquarium fish, it’s best kept in their own aquarium.

Unlike Gambusia, the guppy can easily be held together with other living owners.


Guppies are calm fish that like to be kept in a group. They are active swimmers, and they almost always move.

Male guppies often chase females and try to impress them by shaking their fins.

If your fish are continually hiding, this may indicate that they are stressed or sick.

Guppies are pacific fishes or aggressive?

Studies show that when the guppies become aggressive, their eyes go black.

In particular, the pupil (the coloured ring around the pupil) changes from silver to deep black, and the changes are rapid. It’s not clear how Guppy darkens her eyes.

The big Poecilia R. does it to the little Guppies who can win in the fight, but the little Guppy doesn’t reciprocate the gesture.

Guppies are a very colorful and sweet fishes, perfect for beginners and experienced fish farmers.

They do not hide often, and fish that are continually moving behind rocks, and plants can be stressed, sick, or vulnerable by other fish.

Remember that their natural environment have few plants, rocks and woods!

Are they territorial?

They can gain a little territory, but when that happens, your quiet little guppy may bite its fins and tail or fight other fish.

Watch out for guppies when adding new fish to the aquarium.

This is a time when combat is likely to occur, and guppy can bite their fins and tail to attack new fish.

Guppies can attack the other ones, especially those of the same sex.

It can also attack large slow-swimming fish with tail fins and long tails, such as Molly.


Many fish are compatible with Poecilia. There is no problem maintaining the aquarium for Guppy only.

However, some owners may want to keep a variety of fish and create an community aquarium with Guppy, instead of creating an exciting natual environment (Biotope)

If your aquarium has only Guppy, this may look a little bare, as the Guppy’s swimming level is at the top and center of the aquarium. The bottom of the aquarium may be empty.

Small peaceful fish are the best aquarium companions for Guppies and avoid those who stop biting guppy tails!

There are almost 10 to 15 fishes that live with Poecilia Reticulata.

Still, we have created a list of fishes that are safe options and compatible with Guppies:

  • Corydoras Catfish (Corydoras julii )- A type of catfish that swims relatively slowly and has a gentle roommate. It is also ideal for collecting leftovers in the aquarium. Corydoras catfish is an excellent tank companion with Guppy, which occupies the space at the bottom of the aquarium because guppies usually swim in the top and middle rows of the aquarium.
  • Swordtails ( Xiphophorus helleri ) A swordtail that can adapt to different water conditions is a live fish that reproduces very efficiently and makes friends with other live fish such as the guppy and the platypus. Named after a long sword-shaped fin at the bottom, the unique colour is also a striking feature if you want to create a unique aquarium.
  • Platies (Xiphophorus maculatus) Another living species, Platies, is a great guppy companion. Plati is a beautiful little jewel that does not need water-related conditions like a swordtail as it has many different colors and patterns. They are calm, and apart from Guppy, Molly, Swordfish, Catfish, and Tetra get along well. These are all good friends for guppies. Plati has an appetite and eats flakes, frozen foods, freeze-dried bloodworms, fruit flies, and mosquito larvae.


They usually don’t live very long, but because they multiply very often, there should be no problem maintaining this small group of wizards at all times.

Guppies live in captivity for about one to three years.

The study has not found any showing that female guppy lives longer than male guppy, or vice versa.

Females and males live longer if they are separated.

If a female guppy always gives birth to a young one, life expectancy may be shortened.

Male Poecilia will always have a shorter life if mated with a female.

in nature Poecilia R. life is related with the presence of predator fishes as Macrobrachium shrimp.


The Poecilia Reticulata and the other most alive fish are generally healthy fish and resist a variety of water parameters.

These hardy fish don’t get very sick.

They are only affected by a few diseases, but guppies should be healthy enough to keep most guppies away if you set up the aquarium properly and provide them with good food, and treatment is minimal.

You must pay attention to the quality and temperature of the water.

Even if a guppy gets sick, it is essential to detect guppy disease and treat it immediately .

If movement or swimming seems abnormal or abnormal, the guppy can be infected. So, it would help if you treated it immediately.

The disease causes the tail fin to turn yellow and adhere to the things that cause pain

The cause of the disease is a bacteria which originates from the wound

If you put guppy in a medicated bath, the symptoms will improve. You can also use saltwater.

Even with a small number of illnesses, adding saltwater or changing guppy water can improve symptoms
