Secrets to Successful Bronze Guppy Keeping

The Bronze Guppy is a Guppy with more than 25% gold color on the whole body, including scales detailed in dark. The vast majority of Bronze guppies competing in show circuits have either Red or Green bi-colored tails. The recessive bronze trait that runs along the scales in black makes it eligible for the Bronze category.

The secret to successful bronze guppy keeping is maintaining high water quality in their tank. Because bronze guppies are extremely sensitive to water quality, they rapidly get ill if the conditions are not good. Always monitor your water parameters and make changes if necessary. A decent filtration system is also required for keeping bronze guppies healthy and happy. Providing your bronze guppies with many hiding places is also important.

These small fish are more prone to stress if they do not feel secure in their surroundings. These little creatures will become anxious if they do not have a safe refuge to retreat to. To give them the protection they require, add plenty of plants and other decorations to their aquarium.

Just remember to provide them with the love and attention they deserve and they will surely reward you with their beautiful colors and charming personalities.

Bronze Guppy Care

Although Bronze Guppies are low-maintenance fish, there is still some preparation required before making them a part of your home.

To maintain nitrate levels in your guppy tank at a tolerable level, you must perform a partial water change every second week. If your tank is heavily stocked or you're feeding it frequently due to a large number of fry, you might want to do this once or even twice a week. If you're using tap water in your aquarium, remember to use a water conditioner.

Maintaining your fish tank can be a delicate task. To ensure that you are doing enough, measure your water parameters regularly with a liquid or strip test kit. This will help you identify any potential problems early on, before they have a chance to cause harm to your fish.

Bronze Guppies are not particularly demanding when it comes to food, but they should be fed a variety of foods to ensure that they get all the nutrients they need.

To keep your Bronze Guppies healthy, it is important to provide them with a clean and stress-free environment. A well-maintained aquarium with plenty of hiding places and a varied diet will go a long way in keeping your fish happy and healthy.

Bronze Guppy Size 

The Bronze guppy averages 6cm in length when fully grown. The females are somewhat bigger than the males. The Bronze Guppy female, like other captive strains, is more delicate than her wild counterparts. Their size makes them vulnerable to becoming lunch for larger fish, so it is important to take care when choosing tank mates. The main factors that influence the growth of your fish are sex, age, genetics, and environment.

Bronze Guppy Lifespan

Under ideal conditions, Bronze Guppies can live up to 4 years. However, in captivity, they rarely exceed 2-3 years of age. The biggest threat to their lifespan is poor water quality, which can cause them to succumb to disease very quickly.

Bronze Guppy

Bronze Guppy Appearance

The Bronze Guppy is a small, peaceful fish that is popular among aquarists of all levels of experience. These beautiful little fish are easy to care for and make a great addition to any community aquarium.

As their name suggests, Bronze Guppies have a metallic bronze or gold coloration on their bodies with black outlines. Their tails are usually two-colored, with either red or green combined with black.

The Bronze Guppy female has a pale orange body and an attention-grabbing, beautiful orange-bronze tail. This color morph might have slight variations, and the colors are usually more subtle in females. The males of this species have brighter colors and a gonopodium, which is a modified anal fin used for reproduction.

Females are typically larger and more drab-colored, and lack a gonopodium. When compared to males, female Bronze Guppies also have a more rounded belly, due to their ability to carry eggs. When comparing males to females, the latter are usually larger in size.

There are several different types of Bronze guppy fish. Some of the most popular include

Bronze Red Tail Guppy, Golden Bronze Tiger Guppy, and Bronze Moscow Guppy. Red Bronze Male Guppy is high in demand due to its beautiful tail and fins.

While the different morphs of Bronze Guppy might have different patterns and colors, they all share some common features.

Sexual Dimorphism

There are different ways to tell apart the sexes of your Bronze Guppies. Here are some of the most common:

Body size

The most distinct difference between male and female guppies is their size. Females are always significantly larger than males.

Body shape

Compared to males, female guppies have a more rounded body shape, which is especially emphasized when they are pregnant. In contrast, males have a very slender build.


In comparison with their body sizes, male guppies have bigger fins. Their fins are frequently more heavily patterned and colored as well. Male guppies have an anal fin that is adapted into a structure called the gonopodium. The male's anal fin is narrow and elongated, while the females is triangular.


In general, male guppies are much more boldly colored and patterned than females. The pregnant female guppies have a distinct marking that distinguishes them from males. A dark triangular marking on the belly, in front of the anal fin is known as a gravid spot. This will confirm that the fish is a pregnant female.


Females spend the majority of their time foraging, whereas males spend a lot of time swimming around the females, hoping to catch their attention.

Bronze Guppy Behavior

Bronze Guppies are peaceful fish that do well in community tanks. They are active fish that enjoy swimming and exploring their surroundings. These little fish are not shy and will often be the first to greet you when you approach the aquarium.

Bronze Guppies are gentle and make good tank mates for other peaceful fish. They are not aggressive and will not bother other fish in the tank. However, males can be territorial with each other and may chase each other around. If you have multiple males in the same tank, it is best to provide plenty of hiding places so that the less dominant fish can escape the aggression.

Females are typically more laid back than males and get along well with each other. However, like all fish, they can have their mood swings and may chase each other around from time to time.

Bronze Guppies are not known to be fin nippers, but their long fins can make them targets for fin-nipping fish.

Bronze Guppies are social creatures and do best when kept in groups. A group of 6 or more Bronze Guppies will help reduce aggression and provide your fish with a sense of security. These tiny fish does not destroy live plants and can be a good addition to a planted aquarium.

Bronze Guppy Feeding & Diet

Bronze Guppies are omnivores and they are not fussy eaters. They will consume a variety of food items. To ensure your fish are getting all the nutrients they need, supplement their diet with high-quality flake food. A more diverse and healthy diet for your pet can be achieved by supplementing their regular food with unprocessed items such as bloodworms, daphnia, or brine shrimp. Incorporating these into your fish's diet a couple of times a week will lead to a happier and healthier fish.

As with all animals, it is important to not overfeed your Bronze Guppies. These little fish are known to eat until they are stuffed, so be sure to only give them as much food as they can eat in a couple of minutes. It is also important to remove any uneaten food from the tank to prevent water quality issues.

Bronze Guppy Tank Mates

The peaceful temperament of Bronze guppies is one of their most appealing features. They are brave little fish that are always busy and visible in the aquarium. They get along very well with other tropical freshwater fish.

A few factors you'll want to consider before picking tankmates for your Bronze guppy are:

Water parameter compatibility 

Bronze Guppies are best suited for living in hard, alkaline water. Therefore, their tank mates should thrive in similar conditions.

Guppies are also known to be nimble jumpers, so a tight-fitting lid is a must.


Because Bronze Guppies are small fish, they do best with tank mates of a similar size. Larger fish may view them as potential snacks. Conversely, smaller fish may become targets of bullying by the guppies.


As we mentioned, Bronze Guppies are peaceful fish. They do best with tank mates that share a similar temperament. Aggressive or nippy fish will only stress them out and may even cause them to become ill.

Now that you know what to look for, here are some great Bronze Guppy tank mates:

  • Platys
  • Corydoras catfish
  • Mollies
  • Least killifish
  • Swordtail
  • Dwarf neon rainbowfish

Some of the tankmates to avoid are:

  • Gouramis
  • Bettas
  • Serpae tetras
  • Large cichlids
  • Tiger barbs
  • Fish that need soft acidic water

A little research goes a long way in ensuring a happy and healthy aquarium. So always be sure to ask your local fish store or do an online search before adding any new fish to your tank.

Bronze Guppy

Bronze Guppy Tank Setup

Bronze guppies are easy to care for and make great additions to any community tank. However, there are a few things you need to know in order to keep your bronze guppies healthy and happy.

When it comes to setting up a tank for your bronze guppies, you need to make sure that you have the proper equipment and supplies. Here are the basics that you need:

Tank Size

The minimum tank size for a Bronze Guppy is 10 gallons. However, because a small tank like this would only be suitable for a small number of male fish, a 20 gallon tank would be a much better option. If you want to keep a large number of Bronze Guppies, or other fish in the same tank, then a 50-60 gallon aquarium would be more appropriate.

Also use a lid on your tank as guppies are excellent jumpers.

Water Conditions

Bronze Guppies are tropical fish and prefer warm water that is between 72 and 82 degrees Fahrenheit. They also prefer a neutral pH level of around 6.8 to 7.8, although they can tolerate a slightly higher or lower pH level. It is important to test your water regularly to ensure that these levels are maintained.


Filtration is key to a guppy's health, just like any other tropical fish. Any type of filter rated for your aquarium's size or greater will work. Although maintaining healthy Bronze guppies does not require the most costly filter, it is suggested that you run a slightly larger model. A better choice is to use two filters for safety and when your fish start breeding there will be an increase in bioload. A power filter is a great option for those who want both filtration capacity and budget for their guppies.


Bronze Guppies are tough fish that can survive in temperatures as low as 70 degrees Fahrenheit. Pregnant guppies are more sensitive to ich infections at lower temperatures, so it's recommended that breeding fish be kept at 78-80°F. So if you use an aquarium heater, the process will be much easier!


Unlike some fish, Bronze Guppies do not have specialized lighting needs and will thrive under standard fluorescent or LED bulbs. If you want to grow a lot of live plants, high-quality lighting is a must. Keep your guppies on a regular 6-8 hour light schedule using a timer for ease.

Live Plants 

Guppies enjoy living in planted aquariums, and the cover provided by plants is a great location for guppy fry to play. Not only do plants help improve the oxygen levels in the water, but they also take up nitrates from the water column.

Guppies will nip at decaying plant material and consume microorganisms from your plants, however they seldom harm live plants. Because guppies prefer hard, alkaline water, you have only a limited number of live plants to choose from.

Some great plant choices for a guppy aquarium are:

  • Anacharis
  • Hornwort
  • Java fern
  • Amazon frogbit

If you wish to add artificial plants to your aquarium, make sure that they are made of a soft material such as vinyl so that your guppies cannot hurt themselves.


The Bronze Guppy is not picky about ornaments and decorations. They're a confident, energetic species that don't stay hidden for long. Let your creativity flow when choosing decorations for your aquarium based on the style or theme you are putting together! Best decoration choices would be:

  • Caves
  • Bogs
  • Rocks
  • Driftwood


The substrate is the material at the bottom of your aquarium that can range from sand to gravel to rocks. For Bronze Guppies, any type of substrate will work as long as it does not have sharp edges that could tear their fins.

A good rule of thumb is to use 1-2 pounds of substrate per gallon of aquarium size. A light-colored substrate will make your guppies' colors pop, while a dark substrate will make them appear brighter. Plain white gravel is also an option and is often used in guppy breeding tanks.

Some great substrate choices for a Bronze Guppy aquarium are:

  • Aragonite
  • Gravel
  • Sand
  • Peat moss
  • Composted soil

If you have all the necessary supplies, you're ready to set up your guppy aquarium!

Bronze Guppy Breeding 

Breeding Bronze guppies is simple, making this a fantastic species to start with if you've never handled tropical fish before. Guppies are livebearers, which means that female guppies give birth to baby fry who are already alive. A female guppy can give birth every single month, quickly populating your fish tank!

After just 2-3 months, female guppies can start reproducing, although it is preferable to wait a little longer before they begin. Guppies' generation time is so quick that they make ideal breeding candidates for projects.

To ensure that your baby guppies are healthy, it's best to start with a group of 6-10 young adult guppies. This gives you the greatest chance of getting a good mix of males and females. Once you have your breeding group, you can separate them by sex or let them live together.

If you decide to keep them together, the males will constantly chase the females and nip at their fins. This can stress the females out and affect their health, so it's generally recommended to keep them separated.

If you have a large enough aquarium, you can keep your breeding guppies in the same tank as your other fish. Otherwise, you'll need to set up a separate breeding tank. Here are a few tips for setting up a breeding tank:

  • The breeding tank should be at least 10 gallons in size
  • The water should be kept at 78-82 degrees Fahrenheit
  • The pH level should be between 7.0 and 8.0
  • The breeding tank should have plenty of hiding places for the fry and the adults

Once your breeding tank is set up, you can introduce your chosen guppies to their new home. If you have a mix of males and females, they will start breeding on their own. Otherwise, you'll need to manually introduce a male and female guppy to each other.

To do this, simply place the male and female guppy in a small container such as a cup or jar. Then, slowly pour the water from the container into the breeding tank. This will give the guppies time to get used to each other before being placed in the same tank.

Once the guppies have been introduced, they will start breeding immediately. Within a few weeks, you should see baby guppies swimming around the tank!

Bronze Guppy Fry

Guppy fry are simple to take care of. You won't have to worry about other fish eating your eggs since they are born alive. Since adult guppies will eat fry, it is best to keep them separate to improve the babies' chances of survival.

Catching all of the tiny fish to move them to a separate tank is not going to be an easy task. A healthier option for your fry tank is to move a pregnant female over! After she has given birth, the mother fish can go back into the main tank.

Adding a breeder box to your tank is another excellent choice, which is less stressful for the pregnant lady. If you're not too concerned about a few of the babies getting eaten, then try growing some floating plants in the tank. The plants will provide them with a place to hide until they are big enough to swim around freely. Water wisteria is ideal for this purpose, but Java moss will work just as well or even better.

Guppy fry is a tiny but resilient fish. They can eat the same flake as the adults, but you'll want to crush it on them. You can grind the flakes in a pepper grinder or simply crush them in your hand.

As they grow, you can start feeding them brine shrimp and daphnia. Guppy fry grows quickly, so you'll need to feed them several times a day. Once they reach 1/2 inch in size, they can be moved to the main tank.

Bronze Guppy Diseases

Guppies are robust fish that are not particularly prone to any difficulties. A high level of stress is often the root cause of health problems. Here are some of the most effective methods for preventing guppy illness:

  • Maintaining your aquarium on a regular basis is essential for keeping the water clean and clear.
  • Overfeeding your fish is something to be avoided.
  • Overstocking your aquarium can be detrimental to the health of your fish.
  • It is important to maintain the correct water parameters in order to keep your fish healthy and happy.
  • Be selective about the fish you put in your tank. Some fish are more aggressive than others and may not do well together.

Despite your best efforts, sometimes poor health is unavoidable. Here are some of the most common guppy health issues:

Ich (white spot disease)

Ich is a common guppy disease that is caused by a type of freshwater parasite. This disease is characterized by small white spots on the body and fins of the fish. Ich can be fatal if left untreated, so it is important to take action as soon as you notice the symptoms.

The best way to treat ich is to raise the temperature of the water. This will speed up the life cycle of the parasite and make it easier to remove with a fishnet. You can also add salt to the water, which will help to kill the parasites.

If you have a severe case of ich, you may need to treat your fish with medication.

Columnaris (Saddleback/ cotton wool disease) 

Columnaris is a bacterial infection that manifests as white patches on the body and fins of fish. The disease gets its name from the characteristic white "saddle" that forms near the base of the tail. This infection can quickly become fatal, so it is important to take action as soon as you notice the symptoms.

The best way to treat columnaris is with a broad-spectrum antibiotic. You can purchase these antibiotics at your local pet store or online.

Gill flukes 

Gill flukes are parasites that attach themselves to the gills of fish and cause respiratory distress. This can lead to a loss of appetite, lethargy, and even death. Gill flukes are most commonly found in brackish water environments.

Camallanus worm

Camallanus worm is a parasitic infection that manifests as red worms protruding from the fish's anus. This disease is often fatal if left untreated. The best way to prevent Camallanus worms is to maintain a clean and well-maintained aquarium.

If you notice any of these symptoms in your fish, it is important to take action immediately.

Hexamita (Hole in the head)

Hexamita is a parasitic infection that manifests as small holes in the head of the fish. This disease is often fatal if left untreated. The best way to prevent Hexamita is to maintain a clean and well-maintained aquarium.

If you notice any of these symptoms in your fish, it is important to take action immediately. These diseases can quickly become fatal if left untreated. Be sure to consult your local pet store or veterinarian for the best course of treatment.
