Guppy Care Guide: Lifespan, Size, Diet, Breeding, and More

Guppy Fish Tank Setup

Tank size

One of the most important things to remember when setting up a guppy fish tank is to choose the right size tank for your guppies. They should have at least 10 gallons of water per guppy.

Water temperature

Guppies are native to tropical climates, so you’ll need to recreate that environment in your tank. You can do this by using a tropical fish tank heater to maintain the water temperature between 72-82 degrees Fahrenheit.

Filtration system

Finally, you need to make sure the water is clean and well-filtered. Guppies are very sensitive to water quality and will not do well in a dirty or poorly-filtered tank. Be sure to change the water regularly and use a good filter system to keep the water clean.

When it comes to filtration, you have a few different options.

A hang-on-back filter is a good choice for a small guppy tank. You can also use an internal filter if you prefer. Just make sure that the flow rate is not too strong, as guppies are not very strong swimmers and can be easily swept away by a strong current.


Another important thing to remember when setting up a guppy fish tank is to include plenty of hiding places and plants in the tank for them to swim around and hide in.

Guppies are very shy fish and will spend most of their time hiding if they don’t feel safe. It’s important to provide them with plenty of places to hide so they can feel comfortable in their new home.

Number of fish

When you have everything set up for your new guppy fish tank, it’s time to add your fish! Start with a small group of 3-5 fish and let them acclimate to their new home. Once they are settled in, you can start adding more fish until you reach the desired stocking level for your tank.

What Is The Best Tank Size For Guppy Fish

While guppies can technically be kept in tanks as small as 5 gallons, it is generally recommended to keep them in tanks of 10 gallons or more? This allows them plenty of room to swim and also provides space for plants and other decorations.

You can also get away with a 5-gallon tank if you only have a few fish, but keep in mind that they will need more frequent water changes in a smaller tank.

A good rule of thumb is to have one gallon of water for every two inches of fish. So, if you have ten guppies, they should have a 20-gallon tank.

If you plan on keeping multiple guppies together, it is important to remember that they are social creatures and do best in groups. For this reason, it is recommended to keep at least 3-5 guppies together in a single tank.

Keeping more guppies together will also help to spread out the aggression that can sometimes occur between individual fish.

Water Requirements for Guppy Fish

When keeping guppies, one of the most crucial factors to consider is their water requirements. Guppies are extremely sensitive to changes in water quality and water conditions. So, it is critical to keep them in a steady habitat.

A regular supply of fresh, clean water is the most crucial water needed for guppy fish. Guppy fish are extremely sensitive to water quality, and even minor changes in water chemistry can induce stress or illness. As a result, it is critical that they perform regular water changes and employ a high-quality filter system in their tank.

Water temperature

Guppies are tropical fish and prefer water that is on the warmer side, between 72-82 degrees Fahrenheit. If the water temperature dips below 72 degrees, guppies will become sluggish and may even stop eating. In extreme cases, low water temperatures can lead to death.

On the other hand, water that is too warm can also be harmful to guppies. temperatures above 82 degrees Fahrenheit can cause stress and potentially lead to death.

pH Levels

Guppies prefer water that is slightly acidic to neutral, with a pH level between 6.5 and 7.5. Water that is too alkaline (pH over 7.5) can cause health problems, such as gill damage, while water that is too acidic (pH below 6.5) can lead to problems with digestion and metabolism.

If you’re not sure what the pH level of your water is, we recommend using a reliable test kit such as the API Freshwater Master Test Kit. This kit will test not only the pH of your water, but also the levels of ammonia, nitrites, and nitrates – all important factors in maintaining a healthy aquarium.

Water Hardness

Guppies prefer water that is on the softer side, with a hardness level between 5 and 15 dH. Water that is too hard (over 15 dH) can cause health problems such as kidney damage, while water that is too soft (under 5 dH) can make guppies more susceptible to disease.

Plants for Guppy Fish

If you’re looking to add some plant life to your guppy fish aquarium, there are a few things you need to consider.

  • First, what kind of plants do you want? There are many different types of aquarium plants available, so it’s important to choose ones that will thrive in the environment you’re creating for your fish.
  • Second, what size plants do you need? Guppies are small fish, so they won’t need large plants to feel comfortable and safe.
  • Third, what color plants do you want? This is mostly a matter of personal preference, but it’s important to consider how the plants will look in your aquarium.

Once you’ve considered these factors, you can start looking for specific plants that will work well in your guppy fish aquarium.

When choosing plants for your guppy fish aquarium, it’s important to consider the needs of your fish. Guppies are small, so they’ll feel more comfortable in a tank with smaller plants.

They’re also relatively tough fish, so plants that can withstand a wide range of water conditions are ideal. Java ferns, hornwort, and anacharis are all good options for a guppy fish aquarium. If you want to add some color to your tank, consider adding red or green Cabomba plants.

Lighting for Guppy Fish

When setting up an aquarium for guppies, one important thing to remember is the lighting. Guppies prefer well-lit water, so it’s crucial to choose a light that will provide adequate illumination for the entire tank.

There are a few different types of lights that can be used for aquariums, and each has its own advantages and disadvantages.

One popular type of light for aquariums is fluorescent lighting. Fluorescent lights are inexpensive and do a good job of lighting up the entire tank. However, they can produce a lot of heat, which can be a problem in tropical fish tanks.

Another type of light that can be used for aquariums is LED lighting. LEDs are more expensive than fluorescent lights but produce very little heat and last a lot longer. LEDs are also available in various colors, so you can choose a light that will create the perfect environment for your guppies.

No matter what type of light you choose, it’s important to ensure that it is positioned correctly in the aquarium.

The light should be placed above the water to illuminate the entire tank. Try to position the light so it reflects off the gravel or other substrate in the aquarium. This will help to create a more natural lighting environment for your guppies.

Filter for Guppy Fish

A filter is a device that helps to remove impurities from water. It is an important part of keeping a healthy aquarium. Different types of filters are available in the market, and each type has its own set of pros and cons.

Canister filter

The most common type of filter used for guppy fish tanks is the canister filter.

Canister filters are very efficient in filtering out particles and debris from the water. They are also quite easy to maintain and can be hidden away from view, which is essential for keeping a neat fish tank. However, canister filters can be pretty expensive and they require regular maintenance.

Hang-on-back (HOB) filter

Another popular filter for guppy fish tanks is the Hang-on-back (HOB) filter. HOB filters are less expensive than canister filters, and they are also relatively easy to maintain. However, HOB filters are less efficient in filtering out particles and debris from the water.

Internal filters

Finally, there are also internal filters available. Internal filters are the most affordable type of filter. Still, they are also the least efficient in filtering out particles and debris. Internal filters are not recommended for use in guppy fish tanks.

No matter which type of filter you choose, it is vital to regularly clean and maintain it to ensure that it is working correctly. A dirty or clogged filter can cause severe problems for your fish, so it is important to keep it clean. Regular maintenance will also help to extend the life of your filter.

How often to change Guppy water

It is generally recommended to change 25-50% of the water in a guppy tank every week. This helps to keep the water quality high and prevents build-up of toxins that can be harmful to the fish.

If you have a lot of plants in the tank, you may not need to change as much water as they help to keep the water clean. However, if you have a lot of fish in the tank or the tank is heavily decorated, you may need to change more water to keep the quality high.

How often should you clean Guppy tank

You should clean your guppy tank at least once a week. However, if you have a lot of fish or if your tank is particularly dirty, you may need to clean it more often.

To clean your guppy tank, simply remove all of the water and then scrub the inside of the tank with a soft cloth or sponge. Be sure to rinse the tank out well before adding fresh water.

How to introduce a Guppy to a new Tank

water requirements for guppy fish

When you first get your Guppy, it is important to properly acclimate him to his new surroundings. Here are some tips on how to do so:

  1. Start by acclimating the Guppy to the temperature of the water in the tank. This can be done by floating the sealed bag of fish in the tank for 30 minutes, then slowly adding a cup of water from the tank to the bag every 10 minutes.
  2. After the Guppy has had a chance to acclimate to the temperature, it’s time to add him to the tank. If you have a small tank, add the Guppy last so that he has plenty of space to swim around. If you have a larger tank, you can either add him in with the other fish or add him after they’ve had a chance to explore the tank and get comfortable.
  3. Once the Guppy is in the tank, make sure to keep an eye on him and monitor his behavior. He may be a little shy at first and hide among the plants or decorations, but he should start to come out and swim around after a day or two.
  4. It’s important to remember that Guppies are social creatures and do best when kept in groups. If you only have one Guppy, consider adding another fish or two so that he has some companions.

How to transfer Guppy Fish

There are a few different ways that you can go about transferring your guppy fish. You can either use a net to scoop them out, or you can pour them into a new container.

  • If you’re using a net, make sure that it is big enough to fit all of the guppies comfortably. It’s also important to make sure that the net doesn’t have any holes in it, as this could cause some of the fish to escape.
  • To pour the guppies into a new container, you’ll need to find one that is large enough to accommodate them. You’ll also want to make sure that there aren’t any sharp edges on the container, as this could hurt the fish.
  • Once you have your new container ready, slowly pour the guppies into it. Be careful not to pour them in too quickly, as this could cause them to get hurt.
  • Once all of the guppies are in their new home, you’ll need to add some water. Make sure that the water is the same temperature as the water they were in before, as sudden changes in temperature can be harmful to fish.

What do Guppy Fish eat?

Guppies are omnivores, which means that they will eat both plants and animals. In the wild, guppies typically eat algae, small insects, and crustaceans. However, when kept in captivity, they can be fed a variety of different foods, including pellets, flakes, live food, and frozen food.

One of the best things you can do for your guppy fish is to provide them with a variety of different foods. This will ensure that they are getting all of the nutrients and energy they need to stay healthy and active.

  • Live foods such as brine shrimp, daphnia, or bloodworms are a great way to add some variety to your guppy’s diet and provide them with a source of live protein. Frozen foods such as mysis shrimp or krill are also a good option and can be thawed and fed to your guppies as needed.
  • You should also offer them a variety of vegetables, such as zucchini, spinach, or peas. Guppies love to nibble on live plants, so including some live plants in your aquarium can be a great way to provide them with both food and entertainment.

When it comes to feeding guppies in captivity, there are a variety of commercial foods available that will provide them with the nutrients they need.

  • Flake food is one of the most popular types of food for guppy fish. These flakes are designed to sink to the bottom of the tank, where most guppies spend the majority of their time.
  • There are also pellet foods available that are similar to flake food but slightly larger in size. Many guppy owners choose to feed their fish a mix of both flake and pellet food.

How to Feed a Guppy Fish

When it comes to feeding guppies, less is definitely more.

A good rule of thumb is to only feed them as much as they can consume in two minutes. Once you’ve determined how much food your guppies can eat in this amount of time, you can then feed them this amount once or twice per day.

It’s also important to keep an eye on your guppy’s food intake and make sure they’re regularly eating. If you notice that your fish are leaving a lot of uneaten food in the tank, this is a sign that you’re feeding them too much.

On the other hand, if you notice your guppies seem skinny or are constantly searching for food, this is a sign that they’re not getting enough to eat, and you should increase their food intake accordingly.

How Much Should I Feed My Guppy Fish

It is generally recommended that you feed your guppy fish two to three times a day. It is best to feed your guppies small amounts several times per day rather than one large meal.

The amount of food that you give them should be based on their size and the type of food that you are feeding them.

  • For example, if you are feeding them pellets, you should give them about three pellets per fish.
  • If you are feeding them live food, you should give them about six live foods per fish.
  • You can adjust the amount of food based on your fish’s appetites and activity levels.

If you notice that your fish are not eating all of the food that you are giving them, you should reduce the amount that you are feeding them. If you notice that your fish are overeating, you should increase the amount of food that you are giving them.

How often do Guppy Fish poop

Guppy fish are said to be one of the cleanest fish in the aquarium trade? They are known to produce very little waste, and their poop is often not easily detected in the water. So, just how often do these little fish actually poop?

Generally speaking, you can expect your guppy fish to defecate once every 24-48 hours.

However, there are a few factors that can affect this, such as the type of food they’re eating and their overall health. If your guppy fish seem to be pooping more or less than usual, it’s always worth checking with your vet to rule out any potential health problems.

Common Guppy Fish Diseases

common guppy fish diseases

Here are some of the most common diseases that affect guppies, along with symptoms to look out for and treatment options:


Finrot is a bacterial infection that affects the fins and tail of fish. It’s usually caused by poor water quality but can also be brought on by physical damage to the fins (from other fish or objects in the tank). Symptoms include fraying or rotting of the fins, redness or inflammation, and increased mucus production.

Treatment for finrot usually involves improving water quality and adding a bacteria-killing medication to the tank. In severe cases, the affected fins may need to be trimmed back.


Ich is a parasitic infection that affects fish of all kinds, including guppies. It’s caused by a single-celled organism that burrows into the fish’s skin, causing white spots to form. Other symptoms include scratching, inflammation, and lethargy.

Ich disease can be treated with a variety of medications, but the most effective way to get rid of it is to raise the temperature of the tank water to 86 degrees Fahrenheit for two weeks. This will kill the parasite, but the fish need to be closely monitored during treatment to make sure they don’t overheat.


Velvet is another parasitic infection, this time caused by a group of single-celled organisms called dinoflagellates. It’s characterized by a velvety or fuzzy growth on the fish’s skin, along with increased mucus production and clamped fins.

Treatment for velvet usually involves adding a copper-based medication to the tank. As with ich, raising the temperature of the water can also be effective, but it must be done slowly and carefully to avoid stressing or killing the fish.

Hole-in-the-Head Disease

Hole-in-the-head disease is a condition that results in pits or lesions developing on the head and body of the fish. It’s most commonly seen in African cichlids but can affect other fish as well, including guppies.

The cause of hole-in-the-head disease is not fully understood, but it’s thought to be linked to poor water quality and malnutrition. Symptoms include lethargy, weight loss, and – you guessed it – holes appearing in the head.

Treatment for hole-in-the-head disease focuses on improving water quality and providing the fish with a nutritious diet. In some cases, medications may also be used to help clear up the lesions.


Dropsy is a condition that causes the fish’s body to swell up due to fluid retention. It can be caused by a number of different things, including bacterial infections, parasites, and cancer. Symptoms include bloating, lethargy, and clamped fins.

There is no cure for dropsy, but it can sometimes be treated with antibiotics or other medications. In most cases, however, the best course of action is to simply provide supportive care and make the fish as comfortable as possible until it dies.

These are just a few of the most common diseases that affect guppies. By familiarizing yourself with the symptoms of these conditions, you’ll be better able to spot them early and get your fish the treatment they need.

How do you breed Guppy Fish

how do you breed guppy fish

Guppy fish are a popular type of freshwater aquarium fish. They are relatively easy to care for and breed, making them a good choice for beginner aquarists.

Guppy fish are livebearers, meaning they give birth to live young rather than laying eggs. This article will explain how to breed guppy fish in an aquarium setting.

To successfully breed guppy fish, you will need to provide them with a suitable environment.

The tank should be at least 20 gallons in size and well-filtered. It should also have plenty of hiding places for the fry (baby fish) to hide when they are born.

You will also need to purchase or build a breeding trap; this is a small enclosure that allows the fry to be separated from the adult fish until they are large enough to fend for themselves.

When choosing guppy fish to breed, look for healthy individuals with good coloration. The males should have long, flowing tails; the females should be plump and round. Avoid fish that seem sickly or have deformities.

Once you have chosen your breeding stock, it is time to set up the tank. Begin by setting up the aquarium according to the instructions in the article How to Set Up a Freshwater Aquarium.
Then, add the plants and hiding places. Finally, add the breeding trap to the tank.

Now that the tank is set up, you will need to condition the fish for breeding. This means giving them high-quality food and keeping the tank clean. It is also important to maintain stable water conditions; sudden changes can stress the fish and make them less likely to breed.

Once the fish are conditioned, it is time to introduce them to each other. Start by adding a few males to the tank; then, after a few days, add a few females. The fish will likely start breeding on their own within a week or two.

How do Guppy Fish mate?

Guppy fish mate by a process called spawning? This is where the male guppy fish will release his sperm (milt) into the water and the female guppy fish will absorb the milt through her gills.

The milt will then travel to the ovaries, where fertilization will occur. Once fertilization has taken place, the female guppy fish will lay her eggs (usually around 100-200 at a time). The fry (baby guppies) will hatch after around 24-48 hours.

It is interesting to note that guppy fish can store sperm from multiple males in their bodies. This means that a female guppy fish could potentially have fry that is fathered by more than one male.


If you’ve made it this far, congratulations! You are now the proud owner of a guppy fish. These beautiful creatures can bring years of enjoyment, provided they are well cared for.

Your guppy fish will thrive in a well-maintained tank with the proper care. By following the guidelines in this article, you can provide your fish with a comfortable and healthy environment. Keep your tank clean, offer a variety of foods, and provide hiding places and plants for your fish.

With the right care, your guppies will thrive and bring you years of enjoyment. Thanks for reading!
