Golden Guppy Care: Top Tips For Keeping Your Fish Happy and Healthy

The guppy also called the million fish or rainbow fish is one of the world's most popular freshwater aquarium fish species. It is a member of the family Poeciliidae and gives birth to live young, like almost all American members of its family. Guppies are from northeast South America and have been introduced to many locations worldwide, though they originally came from that area.

They are highly flexible and can survive in various habitats and ecological environments. There are many different varieties of guppy, with different colors and patterns. The golden guppy is one of the most popular.

The Golden Guppy is one of several distinct species of Poecilia reticulata guppy developed through years of precise selective breeding. It has a golden shimmer pattern on its entire body, with a slight iridescent hue. The tail of the golden guppy is usually golden, with color gradually reducing towards the end.

These species of fish are easy to take care of and are ideal for beginner aquarium hobbyists. They are also one of the most popular fish to be kept in an aquarium due to their easygoing temperament, and a wide variety of colors, and patterns. If you're thinking about getting a golden guppy for your home aquarium, read on for some top tips on how to care for them.

Golden Guppy Care

Golden guppies are a wonderful addition to any aquarium because they are simple to care for and adaptable. They do well in tank communities with other peaceful fish. These guppies have known for their beautiful golden color and lengthy fins, but they're also low-maintenance and easy to care for. However, you should know a few things about golden guppy maintenance in order to ensure that your fish are satisfied and healthy.

When it comes to golden guppy care, one of the most important things to keep in mind is water quality. Golden guppies are native to tropical regions of Asia, Central America, and Brazil. In the wild, they typically inhabit slow-moving waters like ponds, swamps, and streams. These fish do best in aquariums that mimic their natural habitat as closely as possible.

For example, your tank should have a sandy substrate and plenty of plants for the fish to hide in. These fish are very sensitive to changes in their environment and will not do well in water that is dirty or has a high ammonia content. It is important to test your water regularly and to do regular water changes in order to keep the tank clean. You should also avoid overfeeding your fish, as this can lead to water quality issues.

Another important aspect of golden guppy care is diet. In the wild, these fish are omnivores and their diet consists of live food, frozen food, and flake food. In captivity, you can provide your fish with a variety of commercially available foods. However, it is important to make sure that they are getting enough protein in their diet.

Read on to learn more about golden guppy care, including information on tank setup, diet, and compatible tank mates.

Golden Guppy Size 

The average golden guppy size is about 2.5 inches, but they can grow up to 3 inches long.

If you want your guppies to be as big and healthy as possible, pay attention to their diet and living conditions. Smaller-than-average guppies are usually the result of inbreeding or poor nutrition, so make sure to improve their food and water quality if you notice them on the small side. With the right environment and care, your guppies can reach their full potential size.

Golden Guppy Lifespan

The typical golden guppy's lifespan is 2-3 years, but they can live up to 5 years with proper care. Factors that will affect how long your guppy lives include diet, water quality, and stress levels. To help your fish live a long and healthy life, provide them with a clean tank and plenty of fresh food.

Golden Guppy Appearance

As we mentioned, golden guppies are a variety of the Poecilia reticulata species, that are known for their long-flowing fins and bright and beautiful golden coloration.

The golden guppy has a bright, shimmery gold coloring on its entire body. The tail is also usually gold, with the color gradually lightening towards the end. They have black eyes and long fins that flow behind them as they swim.

The guppy's coloration is based on the colors of its parents and the environment it was raised in.

Golden guppies have a single dorsal fin and an anal fin, just like all guppies. They also have a caudal peduncle, which is the narrow region of their body between the tail and the main fins. This peduncle is utilized to enable fish to swim swiftly through the water.

Golden Guppy Variations

There are many different variations of golden guppies, which is part of what makes them so popular among fish enthusiasts. Some of them are:

  • Full Gold Ribbon Guppy: As the name suggests, these fish are completely gold in color. They have long fins that flow behind them as they swim and their bodies are covered in iridescent scales.
  • 24K Guppy: These species of fish are completely gold with no other coloration. They have long fins and their bodies are also covered in iridescent scales.
  • Golden Pheonix Guppy: The Golden Phoenix Guppy is a bright golden-hued fish with an endearing appearance. Its name is derived from the reddish-yellow patterned tail that resembles the phoenix bird and the black-colored eyes.

Note: Most guppy fish are black, golden, blue, red, yellow, green, white or purple in color. They're more difficult to find and more costly than multi-colored guppy fish.

Gender Differences

Male and female golden guppies are easy to tell apart. Some of the main physical differences between the two genders include:

  • Males are usually smaller than females and have much longer fins.
  • The males also tend to be more brightly colored than the females. They also have a gonopodium, which is a modified anal fin used for reproduction.
  • Females are larger, with shorter fins, and their colors are not as bright.

Golden Guppy Behavior 

Golden guppies are social creatures that enjoy being around other fish and so they can be kept in a community tank. They are not aggressive and will not bother other fish unless they are being harassed. Because they are tiny and inoffensive, the tank must include plenty of hiding places so that the guppies may flee if required. These fish are active swimmers who enjoy being in school. These fish thrive in South American river systems with a sluggish current.

Guppies are very active fish and love to swim around, so they need a tank that is at least 10 gallons. If you have a smaller tank, you may need to get an aquarium chiller to keep the water cool enough for them.

Golden guppies are also known to be good jumpers, so the tank must have a tight-fitting lid to prevent them from escaping.

Golden Guppy Tank Setup

Setting up a tank for golden guppies is not difficult. These fish are not picky and they do well in a variety of water conditions. However, like any other fish, they need a clean and well-maintained tank to stay healthy.

Here are some tips for setting up a golden guppy tank:

Tank Size

The minimum tank size for golden guppies is 5 gallons. However, if you want to keep more than a few fish, you will need a larger tank. There are many benefits to a larger tank, including more space for the fish to swim and very few water quality issues.

If you want to add diverse fish to your aquarium, keep in mind their size and requirements while choosing a tank size.

Water Conditions

Golden guppies are not picky about water parameters. They can live in a wide pH range and a wide temperature range. However, they prefer neutral water with a pH of 6.5 to 8.0. The temperature of the water should be between 72 and 82 degrees Fahrenheit.

Be sure that your water is safe for fish by checking the levels of chlorine, ammonia, and nitrites. You can use a water conditioner to remove harmful chemicals from the water. The nitrates and phosphate levels should also be monitored, as too much of either can cause algae problems.


Golden guppies do not produce a lot of waste, so a simple filter is all that is needed to keep the water clean. A hang-on-back filter or a canister filter will work well for a golden guppy tank. Be sure to choose a filter that is rated for at least twice the size of your tank.

If you have a lot of plants in your aquarium, you may not need a filter at all. Plants help to keep the water clean by absorbing nitrates and other pollutants.


Golden guppies do not need special decorations, but if you want to make your aquarium more attractive, there are many options available.

Driftwood and rocks 

These fishes like to hide when they are feeling stressed, so having some driftwood or rocks in your aquarium will give them a place to hide. Also adding this driftwood and stones to your aquarium might give it a more natural appearance. Make sure the pieces you pick are suitable for aquariums and won't affect the water quality. Touch it and make sure there aren't any sharp or jagged edges that could harm your fish. Before adding it to your tank, clean it thoroughly.


Golden guppies do not need live plants, but they do benefit from them. Plants help to keep the water clean and provide hiding spots for the fish. Live plants also add oxygen to the water.

Some good plant choices for golden guppy tanks include:

  • Java moss
  • Hornwort
  • Anacharis
  • Water sprite
  • Ludwigia

If you can't find these plants in your area, you can also add artificial plants to your tank. Be sure to choose plants that are safe for fish and made from non-toxic materials. Wash them well before adding them to the tank.


Golden guppies do not need a special substrate, but they do need some type of substrate to anchor their plants. A gravel substrate is a good choice for golden guppy tanks. Be sure to choose a substrate that is small enough so that the fish cannot swallow it.

In case you are planning to keep live plants in your aquarium, you will need to add a nutrient-rich substrate. A good choice for live plants is an aquarium soil substrate.


Golden guppies do not need special lighting, but they do benefit from some type of light. Live plants will do best with a full spectrum LED light. This type of light promotes plant growth and also enhances the colors of the fish.

If you are not planning to add live plants to your tank, you can choose any type of light that you like. Golden LED lights are a good choice for golden guppy tanks.

Golden Guppy

Golden Guppy Tank Mates

Golden guppies are peaceful fish, so they can be kept with a wide variety of tank mates. Some good choices for golden guppy tank mates include:

  • Neon tetras
  • Guppies
  • Platies
  • Swordtails
  • Mollies
  • Danios
  • Barbs
  • Corydoras catfish

Do not keep golden guppies with fish that are known to be aggressive or nippy. These fish will stress the golden guppies and may even cause them to die. Some bad choices for golden guppy tank mates include:

  • Betta fish
  • Goldfish
  • Sharks

If you are adding golden guppies to an existing aquarium, be sure to choose tank mates that are compatible with them in terms of water parameters.

Note: Observe your fish closely when you first add them to the tank. Some fish may appear to be peaceful at first, but they may become aggressive as they grow larger. In case of any aggression, remove the aggressor immediately.

Tank Maintenance

Golden guppies are easy to care for, but they do require some basic tank maintenance.

  • Be sure to do a partial water change at least once a week. This will help to keep the water clean and remove any toxins that may have accumulated in the tank. To do a partial water change, remove 10-15% of the water from the tank and replace it with fresh, clean water.
  • Clean the filter regularly. This will help to remove any debris or waste that has accumulated in the filter media. Most filters will need to be cleaned every 2-4 weeks.
  • Be sure to vacuum the gravel and clean any algae that have accumulated on the glass. This will help to keep the tank looking clean and prevent the build-up of toxins.

Note: While changing the water, make sure to use a water conditioner to remove any chlorine or other chemicals that may be present in the tap water. If you do not have a water conditioner, you can use aged water that has been left out for 24 hours.

Golden guppies are not picky eaters and will accept most types of fish food. flakes, pellets, frozen, and live food.

To keep your golden guppies healthy, it is important to feed them a varied diet. They should be fed several times a day, but only as much as they can eat in 2-3 minutes.

Here are some good food choices for golden guppies:

Flakes or pellets: Golden guppies will accept most types of fish food, but they should be given a high-quality diet of flakes or pellets. Read the ingredient label to make sure the food you are choosing is high in protein and does not contain fillers or artificial colors.

Live food: Live food is a great way to add variety to your golden guppy's diet. Live food contains more nutrients than pellets or flakes and will help keep your fish healthy. Some good choices for live food include brine shrimp, daphnia, and blackworms.

Frozen food: Frozen food is a good alternative to live food. It is more convenient and easier to store than live food. Be sure to thaw the food before feeding it to your fish.

Vegetables: Golden guppies also like to eat vegetables. You can offer them blanched spinach, zucchini, and peas. Be sure to remove any uneaten vegetables from the tank so they don't decompose and pollute the water.

What Not To Feed

Golden Guppy Diseases 

Golden guppies are relatively hardy fish, but there are some diseases that they are susceptible to.

Some of the diseases that golden guppies can get include:


Ich is relatively simple to detect and is caused by an ectoparasite (ciliate protozoan Ichthyophthirius multifiliis), which makes it very easy to find. The fish begin rubbing their skin against rocks, plant leaves, or other objects in the aquarium. They can also lose their appetite. You will see tiny white dots on their skin and fins. To treat ich, you will need to raise the temperature of the water and do a partial water change. You may also need to treat the fish with an ich medication.

To cure ich:

  • Gently raise the water temperature to 80 degrees Fahrenheit
  • Add the ich medication to the recommended dose. You can also add aquarium salt at a rate of 1 teaspoon per gallon
  • Keep the water at this stage for 4-7 days and observe
  • Bring the water temperature back to normal gradually
  • Perform a Partial Water Change of about 70%


Velvet disease, while similar to ich, is less often seen in aquariums kept by hobbyists. A fish afflicted with velvet will have its body covered in tiny gold-colored dots, looking like grains of dust. Since this disease is highly contagious, it can quickly spread to all your other fish if you're not careful.

A fish's skin can be distinguished by its velvet. The dots are small, making it difficult to detect in the early stages. When the fish's skin begins to peel off and blood appears, fish keepers often discover too late that something is wrong.

To cure velvet:

  • Velvets can be treated with copper medication to cure them
  • To most effectively treat your aquarium, turn off the lights until the disease is gone
  • Once your fish are symptom-free, perform 70-90 percent water changes

Fin Rot

Rotting fins and tail is a bacterial infection in guppies, which manifests as the fish's fins and tail appearing to be stuck together. This can also be caused by a fungus that grows on nipped fins. In addition, poor water quality and ammonia burns are additional causes of rotting tails.

The cause of rotting fins is important to identify because the treatments for bacterial infection or fungus are different. If there is no damage to the fins and tail but there is a clear sign that they have started rotting, it is most likely caused by bacteria.

To cure fin tail rot:

  • The sick fish should be isolated
  • Treat it with antibiotics
  • If your fish has fin rot caused by a fungus, treat it with special medication – always follow instructions on the packaging
  • To prevent “ammonia burns”, it is important to provide your fish with high-quality water


Among fish, guppies are the most likely to contract the protozoan parasite. Although other fish can get sick from it too, guppies are by far the most common host for this tiny creature.

The parasite latches on to the fish's skin and works its way into the fish's body via their muscle until it reaches circulation.

This parasite usually develops in unheated tanks when water quality is poor.

To cure protozoan:

  • Add a heater to your fish tank so as to keep the water temperature consistent
  • This condition can be treated with early-stage Malachite Green or Formalin
  • In more advanced stages, copper medications such as Seachem Cupramine should be used
  • After treatment, change 50-70% of the water


Although this infection appears to be fungus, it is actually caused by bacteria. The colony of bacteria typically grows as a large white sludge on the fish's mouth or midsection. Because the illness slowly paralyzes their muscle, sick fish have difficulty swimming and lose their appetite.

The infection is highly transmissible and mostly affects female guppies, although male guppies can also be sickened if left untreated. If the disease isn't addressed, it has the ability to wipe out a tank's entire fish population.

To treat Columnaris and mouth fungus:

  • The quickest way to cure Columnaris is to start the treatment process as soon as you notice any symptoms.
  • This condition may be treated with Maracyn or Formalin, which are two common drugs.
  • Adding salt to your tank and aquarium salt can also help: perform a 50% water change and add one teaspoon of salt per gallon every day for three days after the water has been changed. Leave the salt in the water until your fish is completely healed.
  • A 30-minute potassium permanganate (KMnO4) bath can also cure Columnaris, although use this treatment carefully. Potassium permanganate is a powerful oxidizing agent; exceeding 10mg/l in the bath at your own risk can burn your fish.


The most common symptom of poor water quality is lethargy. If your guppy is listless and not interested in swimming around or eating, it's a sign that something is wrong.

Other symptoms include:

  • Gasping for air at the surface of the water
  • Clamped fins
  • White patches on the skin
  • Hanging at the bottom of the tank
  • Loss of appetite

If you notice any of these symptoms in your guppy, it's important to take action immediately. The sooner you address the problem, the better chance your fish has of recovering.


The best way to prevent infections and diseases is to keep a close eye on your fish and their environment. Follow these tips to help keep your fish healthy and happy:

  • Regularly check your fish for signs of illness and disease.
  • Perform regular water changes to keep the tank clean and the water quality high.
  • Don't overfeed your fish; uneaten food can pollute the water and lead to infection.
  • Avoid overcrowding your tank; more fish means more waste and a higher risk of disease.
  • Quarantine new fish before adding them to your tank.
  • Keep your aquarium clean and free of debris.

Golden Guppy Breeding

Guppies are a popular choice for fish breeders because they reproduce quickly and can easily overpopulate a tank. Guppies are also livebearers, meaning they give birth to live young instead of laying eggs.

To breed guppies, follow these steps:

Choose a breeding pair of guppies. Opt for male guppies with large, vibrant fins, and females that are plump with a gravid spot. It's best to go for young pairs of guppies as they will likely have healthier offspring. If you want to increase your chances of breeding, experts recommend selecting 3 or 4 young pairs.

Set up a breeding tank. It's crucial to provide the female guppy with a hiding place in the breeding tank. Live plants or plastic plants may be used for this purpose. It's also important to have a fine-mesh net on hand to collect the fry (baby fish). The temperature of the breeding tank should be maintained at 75-80 degrees Fahrenheit.

After the breeding tank is all set up, it's time to add the guppy pair. Give them an hour to adjust to their new surroundings before letting them loose in the tank. This will help reduce the stress levels of the fish and increase the chances of breeding.

Wait for the fry to be born. The female guppy will give birth to anywhere from 20 to 60 fry at a time. The fry is very small and vulnerable, so it's important to have a net ready to catch them. Once the fry is born, it should be removed from the breeding tank and placed in its own tank.

Feed the fry. The fry will need to be fed several times a day. You can purchase special fry food, or you can feed them live baby brine shrimp. When the fry is about two weeks old, you can start feeding them adult guppy food.

Monitor the fry tank. The fry tank should be kept clean to prevent disease. You should perform a water change every week, and you should remove any uneaten food from the tank. When they are about four weeks old, the fry can be moved to a larger tank.
