Why Green Guppy is Popular Among Fish Keepers

Show quality green guppies are difficult to develop and therefore much sought after. Green guppies are green mixed with a blue iridescence. They can occasionally be disqualified from shows due to the type of light used and the angle of the light, which may turn it blue or green or purple. Female guppies of green strains will show green highlights in their fins.

Green guppy is very popular among fish keepers because of their unique coloration. They are also easy to care for and make a great addition to any aquarium. Green guppy fish are small with teeth in their upper and lower jaws. The bottom of their tank should be gravel, with plants rooted in the substrate and floating vegetation on the surface. They may be kept in a community tank, although fry, long finned species and fin nippers should be avoided as tankmates. Corydoras or Tetras are excellent tankmates. Green guppies can be kept in groups, a 5-gallon aquarium is sufficient for three fish.

Green guppies are easy to care for and make a great addition to any aquarium. To take care of green guppies, you will need a minimum 5-gallon aquarium and the following:

  • Gravel substrate
  • Aquarium Plants
  • Water with Ideal temperature and pH
  • High quality dry and frozen fish food

With little care, your green guppy will thrive and bring you years of enjoyment. They are adaptable to a range of water conditions but do best in well-oxygenated, neutral to slightly alkaline water that is clean and free of ammonia and nitrates.

To help maintain good water quality, it is recommended to do a partial water change of 10-15% every 2 weeks or as needed. It is also important to remove any uneaten food or debris from the aquarium as this can quickly lead to poor water quality. To help keep track of your water quality, we recommend using an aquarium test kit.

Disease symptoms should be examined in your fish and, if anything's wrong, quarantining them is the greatest option.

Guppies are not exclusive to the top level of the water column and can often be seen lower down, near the middle or bottom. They are also not afraid to leap, thus they must be kept in an aquarium with a lid/hood/canopy or at least a lowered water level. They will not eat plants or cause any harm. Guppies are best maintained in pairs or small groups.

Green guppy fish are hardy and adaptable. If you're looking to add some fish to your aquarium that will stay near the top, green guppies are a great option. They can also easily be bred in captivity.

Green Guppy Food & Diet 

Green guppies are omnivorous. In the wild, they feed on insects most of the time. In an aquarium, they may be fed dry, live, and frozen foods; the vegetable matter should be added to their diet. Because Guppies have tiny mouths and stomachs, their food should be small as well. As an alternative to feeding them the same amount at once, we recommend giving them two to three feedings a day with a quantity they can devour in three minutes.

The best food choices for your guppy fish include live bloodworms, tubifex, brine shrimp and corethra. They will also eat high-quality pellets, flakes, and frozen or freeze-dried tubifex and bloodworms.

Green guppies will eat anything, even if it is manufactured food. Flakes, pellets, and other well-known trademarked packaged foods are examples of artificial cuisine for Green guppies. Guppies enjoy eating this sort of food. A diet of frozen vegetables, fruits and other packaged foods will ensure your green guppies are healthy and have strong immunity.

They are a calm species that get along with others as long as the other fish don't nibble on their lengthy tails. Although adult dwarf shrimp are safe, guppies may eat the shrimp fry. Larger, more tranquil invertebrates might also be good tankmates.

Green Guppies will be compatible with other peaceful and small fishes such as:

  • Dwarf Gourami
  • Bristle-nose Pleco
  • Platy
  • Harlequin Rasbora
  • Mollies
  • Cherry Barb
  • White Cloud Mountain Minnow

Green Guppies should not be housed with large predators such as Green Terror, Tiger Barb, Tetra Fish, Angelfish, or Jack Dempsey.

Green Guppy Tank Setup 

In order to keep green guppies healthy and happy, it is important to provide them with a well-maintained tank. Green guppies are relatively easy to care for, but there are a few things to keep in mind when setting up their home.

Tank Size:

For a green guppy tank, you will need at least a 10-gallon aquarium. A 20-gallon tank is even better. If you want to keep more than one green guppy, you should consider a larger tank. Green guppies are social creatures and do best in groups.

1 to 1.25 teaspoons of aquarium salt per gallon is recommended for their tank. Water changes should take place 2-3 times a month. When replacing water that has been lost to evaporation, use plain water--the salt doesn't evaporate, so there's no need to add more.

Ideal Water Temperature: 

The warmer the temperature of the water is, the better it is for Green Guppies, as they are tropical fish. This is because temperature influences the metabolism rate; The higher the temperature, the inverse the lower the metabolism rate.

If the temperature in your aquarium rises, your guppies will not live as long. The length of a pregnancy and the health of the newborns will both be reduced. Newborns will have less resilience to diseases because they are smaller, requiring more medicine.

If you lower the temperature of the aquarium tank, the guppies will grow larger and live longer. Despite the fact that they are prone to illness. Babies born will be heavier and have more health issues as they get older.

Therefore maintaining a stable temperature for keeping guppies healthy is very important. The ideal temperature for guppies is between 18° - 27.7° C(64° - 82° F). Adding a heater to your fish tank will help maintain uniform warmth and keep your guppies healthy.

Ideal pH Levels For Green Guppies 

Green Guppies are tough fish that can live in different pH levels, with the exception of soft acidic water. The optimal pH range for keeping guppies is 5.5 to 8.0. It's critical to maintain optimum Best pH levels for your guppies.


The substrate is the bottom layer of your fish tank. It can be made of gravel, sand, or rocks. For green guppies, it is best to use a fine-grained substrate such as sand because they are small fish with delicate fins. A coarse substrate can damage their fins.


Live plants are a good addition to their tank because they provide oxygen and help keep the water clean. Some good plant choices for green guppies include hornwort, Java moss, and Anacharis. It is best to avoid plants with sharp edges such as sword plants.


Green guppies are not fussy fish and will do well in a simple tank. They do like to hide, so adding some caves or tunnels can be beneficial. Be sure to avoid decorations with sharp edges that could injure their fins.


Green guppies do not require special lighting, but they do prefer dimmer conditions. A regular aquarium hood with fluorescent lighting will be sufficient.


A good filtration system is important for all fish tanks, and green guppies are no exception. A canister filter or a hang-on-back filter will work well for their tank. Be sure to choose a filter with an appropriate flow rate for your tank size.

If you take into consideration the items on this list when setting up your green guppy tank, you will be sure to create a happy and healthy environment for your fish.

Green Guppy Breeding

The name Millions Fish is derived from the fact that this species breeds frequently and produces a large number of young. To reproduce this species in captivity, there should be several females for each male in a densely planted 10 to 20-gallon tank. Pregnant females can be identified by a darkened area behind their anal fin. Their gestation period is about 4 weeks, during which time they will become increasingly round-bellied. The female gives birth to fry, which means she stores the eggs inside her and they hatch while still inside her. Females are able to store sperm in their bodies for up to six months, meaning they can give birth even if no males are present. This implies that guppies are live bearers, as they produce living swimming individuals instead of laying eggs. Mating just one time with a single male is enough for her to have several litters.

Green Guppies are one of the most carefree fish to breed, needing little attention and upkeep. Guppies are also sometimes referred to as beginner's fish because a single male guppy can successfully mate with 3-5 females. Mating is repeated multiple times in order to produce offspring with improved health and immunity.
