Male Emerald Green Guppy

Male Emerald Green Guppies are known for their striking appearance. They are relatively small, typically reaching a length of 1.5 to 2 inches. The key features that make them stand out include:

  • Vibrant Color: As the name suggests, they exhibit a stunning emerald green coloration. The scales on their body shimmer with varying shades of green, creating an eye-catching display.
  • Fancy Fins: Their dorsal fin is elongated and often sports an iridescent edge, making them look even more impressive. The tail fin can be fan-shaped and may have some red or yellow accents, adding to their elegance.
  • Gonopodium: One unique feature of male guppies is their modified anal fin called the gonopodium, which is used for reproduction.

Female Emerald Green Guppy

Females, on the other hand, have a more understated appearance:

  • Subdued Color: Female Emerald Green Guppies are less colorful than their male counterparts. They tend to have a more olive or brownish-green hue.
  • Rounder Shape: Their bodies are rounder, especially when they are carrying fry (baby fish).
  • Shorter Fins: Females have shorter dorsal and tail fins compared to males.


The emerald green guppy is a selectively bred variety of the guppy (Poecilia reticulata), which is a native of northern South America and the West Indies. Emerald green guppies were first developed in the early 1900s by aquarists who were interested in creating new and unique color varieties.

The exact origin of the emerald green guppy is unknown, but it is believed to have been created by crossing different guppies with wild guppies from Venezuela. Over time, aquarists have continued to selectively breed emerald green guppies to improve their color and fin shape.

Today, emerald green guppies are one of the most popular varieties of guppies in the aquarium hobby. They are known for their vibrant color and their relatively easy care requirements.

Tank Setup

Setting up the perfect tank for your Emerald Green Guppies is essential for their health and well-being. Here’s what you need to consider:

Tank Size

Emerald Green Guppies are relatively small fish, but they appreciate space to swim and explore. A tank with a minimum of 10 gallons is suitable for a small group of guppies.

Water Parameters

Maintaining the right water conditions is crucial:

  • Temperature: Keep the water temperature between 74°F and 82°F (23°C – 28°C).
  • pH Level: Guppies thrive in slightly alkaline water with a pH of 7.0 to 7.4.
  • Water Hardness: Aim for moderate water hardness, around 10-15 dGH.

Filtration and Aeration

Invest in a good quality filter and an air pump to ensure proper oxygenation and water circulation. Guppies prefer a gentle current, so adjust the filter flow if necessary.

Substrate and Decor

Use fine gravel or sand as substrate. Add live or silk plants to provide hiding spots and enhance the aesthetics of the tank. Guppies appreciate a well-decorated environment.


Moderate lighting is sufficient. Guppies don’t have specific lighting requirements, but avoid excessive direct sunlight, as it can promote algae growth.

Tank mates

Emerald green guppies are generally peaceful fish and can be kept in community tanks with other peaceful fish. However, it is important to note that male guppies can be territorial towards each other, so it is best to keep only a few males per tank.

Here are some good tank mates for emerald green guppies:

It is important to avoid keeping emerald green guppies with aggressive fish, such as cichlids and barbs. These fish may harass or even kill the guppies.


Emerald Green Guppies

To breed emerald green guppies, you will need a breeding tank and a pair of guppies. The breeding tank should be at least 10 gallons in size and should be well-planted. The water temperature should be between 75 and 78 degrees Fahrenheit.

Once you have set up the breeding tank, add the pair of guppies. The male guppy will begin to court the female guppy by swimming around her and flaring his fins. If the female guppy is receptive, she will allow the male guppy to fertilize her.

After the female guppy has been fertilized, she will carry the eggs for about 28 days. Once the eggs are ready to hatch, the female guppy will give birth to live fry. The fry will be very small and will need to be fed a diet of infusoria or baby brine shrimp.

Once the fry are large enough to eat flake food, you can transfer them to a larger tank.

Here are some additional tips for breeding emerald green guppies:

  • Select a healthy and well-colored pair of guppies to breed.
  • Feed the guppies a high-quality diet.
  • Keep the breeding tank clean and well-maintained.
  • Monitor the guppies closely during the breeding process.
  • Remove the male guppy from the breeding tank after the female guppy has been fertilized.
  • Feed the fry a diet of infusoria or baby brine shrimp until they are large enough to eat flake food.


Emerald green guppies are omnivores, so they need a diet that includes both plant and animal matter. A high-quality flake food is a good staple diet for emerald green guppies, but you should also supplement their diet with live food and frozen food.

  • Frozen food: bloodworms, daphnia, brine shrimp, mysis shrimp
  • Vegetables: blanched spinach, romaine lettuce, cucumber

You should feed your emerald green guppies twice a day, giving them as much food as they can eat in two minutes. Be careful not to overfeed your guppies, as this can lead to water quality problems.

Where To Buy Emerald Green Guppies

You can buy emerald green guppies from a variety of places, including:

Common Diseases

Guppies, including the Emerald Green variety, are susceptible to certain common fish diseases. Being proactive and maintaining a clean tank can help prevent these issues. Here are a few diseases to watch out for:

  • Ich (White Spot Disease): This is a parasitic disease that causes white cysts on the fish’s skin and gills. It can be treated with over-the-counter medications.
  • Fin Rot: Bacterial infection can cause fin deterioration. Clean water and anti-bacterial treatments can help.
  • Dropsy: Swelling of the abdomen can be a sign of dropsy, a symptom of internal bacterial infection. Quarantine affected fish and consider treatment with antibiotics.
