Guppy Care Guide – Requirements & Breeding


If you study the history of the Guppy fish, you will discover that it was named after an individual who apparently had no scientific training, but was a fish enthusiast and a researcher who decided to dig into the guppy fish that seemed to be neglected.

Guppies reign from South America and can be found in Brazil, Venezuela, and Amazon among other countries. 

Guppies are among the livebearer types of fish, like the mollies and the swordtails they thus give birth but don’t lay eggs. They do have a few aka’s such as the rainbow fish or the millions fish, the latter is because of their ability to reproduce at a higher rate. And the rainbow nickname is because they come in a wide variety of colors. 

The millions fish are also in the habit of making a snack out of their young ones, thus it would be a good idea to incorporate enough plant materials in the aquarium so that the guppy fry can hide incase their parents wants to eat them. You might be thinking of separating the fry from its parents but that wouldn’t be a good idea, as you risk stressing them. 

Guppy Tank Requirements 

Beginners and professionals alike will have an easy time tending to their new fish pets, as guppies are one of the easiest fish to care for. So, as you go about acquiring guppies for your tank it would be best if the amount of fish that you acquire resonates with the number of fish that you want to keep. A 10-gallon fish tank can, therefore, comfortably accommodate up to five guppies.

If you are using tap water then you should know that it contains some level of chlorine, and the reason why you should remove the chlorine is that it is a toxic additive that will harm your fish. A new tank, therefore, needs to be de-chlorinated, and the process is simple, just leave the lid of your aquarium open so that chlorine can evaporate, this will probably take a week. 

And to be sure, get a chlorine testing kit, to check that the levels are not too high, but if you feel the process is too complex for you or you don’t have the time just use distilled, filtered or purified water. A large number of guppies call for high water PH, 7.5 should thus suffice and to boost the PH levels in water you could include crushed corals. 

Water temperatures

Aquarists normally use water heaters to regulate the temperatures in their fish tanks, a thermometer should thus be sought to help keep an eye on the temperatures because neither too high nor too low temperatures are good for your fish. Recommended water temperatures are thus 75 to 80 degrees Fahrenheit. 

Sunlight would be a great way of providing illumination in your fish tank, but then again the sun could possibly raise the temperatures of your tank. Novice fish pet owners are therefore advised to use artificial lighting in the tank. 

The Water filter 

The benefit of a water filter in the aquarium might not be readily apparent to beginners; water filters are what keeps your aquarium water fresh. Besides, they help breed the beneficial bacteria, can be used to place active carbon in the fish tank and are essential for removing debris from water. Some aquariums come with their own filters that might need replacement with regard to your aquarium dwellers. 

For example, if you have incorporated shrimps in your aquarium you will need a filter that will not suck them in and kill them. Filters are also of two types the internal and external types that can be adopted for both fresh and saltwater. What’s more is that by incorporating a filter, your tank will be oxygenated.


Plants in any aquarium contribute to their cosmetic look and offer protection to different aquarium dwellers. Both fish and fry will enjoy hiding in between or under the plants, in addition, the best plants need to be live and not plastic because they have a lot of contributions to the aquarium ecosystem. Stones and pieces of driftwood are also a great addition to your aquarium but be sure to clean them, to prevent parasites from getting into your tank and prevent changes in water PH. 


Too much or less light in the fish tank has the ability to deform your guppy, so the easiest way of regulating light in the tank is by using a timer that will switch the lights on and off. Algae also thrive in tanks with too much natural light, therefore, if you decide to use the sun as your source of lighting keep a keen eye on the water temperature. 


Feeding guppies 

Guppies are versatile feeders and will enjoy both wet and dry foods; frozen foods are also a delicacy and they will not run away from live foods. Both humans and animals need a balanced diet to help derive the relevant nutritional benefits; there are therefore the commercially made flake foods for the fish that when combined with freeze-dried brine shrimp, the tubifex worms or the dried blood worms will help offer the necessary nutritional benefits. 

Guppy Compatibility

Guppies will do well in an aquarium with Gouramis, tetras, mollies, corydoras and the platies. However, if you want a vibrant fish tank, you could keep the male guppies only, as they feature the most vibrant colors. Male and female guppies can also be kept together, only that you have to ensure that they are in the ratio of 2:1. 

Guppy Breeding 

Just so you know guppies don’t need your help to breed and will reproduce like no man’s business. The female guppy grows the baby guppy inside their bodies; what happens is that the growing fish uses the egg sac for nourishment, they then hatch inside the female guppy and the female will then give birth to a guppy baby. 

After three or five months of birth, the guppies would have reached sexual maturity and this one you could detect by checking their coloring. The brightly colored ones are usually the males and have a gonopodium, which is longer and narrower than the female’s anal fin. Size-wise the males have a small body structure compared to the females. 

Pregnant female guppies normally have a characteristic dark spot behind their anal fins that gets even darker during pregnancy.
