Activity Level/Temperament

Like most guppies, orange guppies have a very playful and docile disposition. They are generally peaceful with other fish, and enjoy swimming in schools to show off their beautiful fins. As these are active fish, it’s best to provide plenty of space in the tank so they can swim and explore. We recommend a minimum of 10 gallons for a school of four fish, though 20 gallons or larger is best.

Orange guppies will also appreciate having hiding spaces and plenty of plants in the tank. This will make them feel secure, reduce their stress levels, and encourage them to explore more. Many fishkeepers incorporate live plants, driftwood, and rocks into their guppy tanks, creating a functional yet gorgeous habitat that makes their fish feel safe.


In general, orange guppies are a very peaceful species and can be housed with most other small, non-aggressive fish. Some compatible tankmates for orange guppies include:

• Tetras

• Danios

• Platies

• Mollies

• White Clouds

• Ghost Shrimp

With that said, it’s important to ensure that the tankmates you choose are not overly aggressive or larger than your guppies. It’s best to avoid predatory fish such as angelfish and cichlids, as they may prey on small orange guppies. Some fishkeepers have success with keeping bettas and guppies together, but this requires a lot of careful planning and introduction.


What to Feed

As omnivores, orange guppies require a varied diet consisting of both plant matter and meaty foods. Commercial food such as fish flakes and pellets are a great staple for guppies. Just make sure they’re formulated for omnivores and specifically designed for their size. You may need to experiment with different brands to find one that your fish will enjoy.

Fish Food

In addition, orange guppies also appreciate frozen foods as an occasional treat. Frozen bloodworms, brine shrimp, and daphnia are all great choices for these fish. Live foods like microworms and Grindal worms can also be fed in moderate amounts – just make sure to do your research before purchasing to ensure that these foods are safe for your fish.

Finally, supplementing your guppy’s diet with some plant matter is a good idea. Guppies will happily snack on algae wafers and fresh vegetables such as spinach, zucchini, and cucumber. Make sure to blanch these veggies before feeding them to your fish, as raw veggies can cause digestive issues.

How Much to Feed

Just as you would with any other fish, it’s important to feed your orange guppies in small portions and on a regular schedule. These fish should be fed twice a day, but no more than they can consume within two minutes. If you overfeed them, the leftover food will rot at the bottom of the tank, leading to poor water quality and health.

Of course, you should also make sure that every fish is receiving its fair share of food. Monitor your tank closely to make sure that all the guppies are eating, and take note of any fish that seem underfed or lethargic.

What Not To Feed

Although guppies are omnivores, there are still some foods that should be avoided. Foods like beef hearts and raw meat can cause digestive issues in these fish. Nuts, seeds, and other human-grade snacks should also be avoided as they are not nutritionally adequate for your orange guppies.

Finally, while live food can be a tasty treat for your guppies, be sure to avoid feeding wild-caught insects. Wild insects may contain parasites and other pathogens that can harm your fish, so it’s best to stick to commercially produced live foods like brine shrimp and microworms.

Tank Requirements

Tank Size

Most adult guppies grow to a size of one and a half to two inches, so they don’t require particularly large tanks. A 10-gallon tank is generally considered the minimum size for a small school of orange guppies. However, if you keep more than six adults together in one tank, it’s best to upgrade to a 20-gallon aquarium or something even larger.

In addition, orange guppies are prolific breeders, so it’s best to prepare for a sudden population increase. Even if you don’t plan to breed your guppies, pregnancies may happen anyway. In this case, it’s best to have a larger tank with plenty of hiding places in order to accommodate any unexpected babies.

Tank Set-Up

To set up a tank for your orange guppies, you will need the following:

  • Aquarium gravel
  • Live or fake plants
  • Filter
  • Heater (if the room temperature is below 74 degrees Fahrenheit)
  • Decorations like driftwood and rocks

Then, follow the steps below to create a suitable environment for your guppies:

  1. Fill the tank with dechlorinated water and add the necessary filter media.
  2. Install the appropriate filter, heater, and decorations. Ensure that all of these items are properly functioning before adding fish.
  3. Add a layer of aquarium gravel to the bottom of the tank and arrange the plants, driftwood, and rocks as desired.
  4. Wait 24 hours for the water to cycle properly before introducing your guppies.

By providing your orange guppies with a safe environment with adequate hiding places and plenty of vegetation, you can ensure that they will thrive in their new home.

Habitat Requirements

Water Requirements

Guppies may be highly adaptive fish, but their ideal water parameters are still important to consider. For tropical fish like guppies, a temperature range of 73-80 degrees Fahrenheit is recommended. The pH level should stay between 6.5 and 8, with a hardness of 5-30 dGH being ideal.

We also want to dispel the myth that guppies thrive in brackish or salt water. These are freshwater fish and should never be kept in a marine environment.

Filtration Requirements

Every hobbyist will attest that a good filter is an absolute must when keeping guppies. A properly functioning filter will make maintaining ideal water conditions much easier by removing excess waste and other potentially harmful toxins.

One important thing to note is that guppies are sensitive to strong water currents, so we recommend installing an adjustable filter with a gentle flow. This will keep your guppies from becoming stressed out while ensuring that they have enough oxygen in the water.

Heat and Lighting Requirements

The right lighting highlights the coloration in guppies, so we recommend providing your fish with a lighting system tailored to their needs. Any color pattern of lights can be suitable, but daylight-type bulbs will provide your guppies with the most natural environment.

Also, be sure to maintain the water temperature in your tank within the recommended range. If your room temperature falls below 73 degrees Fahrenheit, we suggest investing in a submersible heater for the tank. This will keep your guppies healthy and happy.

Plants and Décor

The playful dynamics in guppies are often highlighted when they have plenty of hiding spots. Live plants and decorations like driftwood, rocks, and caves provide the perfect places for your guppies to relax, explore and live together harmoniously.

We also suggest adding a few floating plants or leaves on the surface of the water. This looks beautiful and provides your guppies with a safe place to take refuge from potential predators.

Habitat Maintenance

Many people decide to set up a guppy aquarium for fun, not realizing how much work it takes to maintain a healthy habitat. Regular water changes and tank cleanings are vital for keeping your guppies happy and healthy.

If you have a community fish tank, we recommend doing a 25 percent water change every week and cleaning the gravel once a month with an aquarium siphon. This helps remove excess waste and debris while ensuring the water is properly oxygenated.

Common Health Issues and Treatment

Now that you know how to care for your guppies, let’s talk about the most common health issues and how to treat them.

Health Issue

Symptoms or Causes

Suggested Action

Fin rot

Fin rot is usually caused by poor water conditions and/or bacterial infections. Symptoms include red lesions in the fins and tail, shredding of the edges of the fins, and discoloration.

To treat fin rot, first ensure that your guppy habitat is properly maintained and that the water parameters are within the recommended range. You can then treat your fish with a broad-spectrum antibiotic, such as Kanamycin or Metronidazole, to help fight the infection.


Dropsy is a bacterial infection caused by stress, poor water quality, or parasites. Symptoms include bloating of the body and scales sticking out at odd angles.

Dropsy is a serious and potentially life-threatening infection, so acting quickly is important. Increase the aeration in the tank, clean the water if necessary, and treat your guppy with a broad-spectrum antibiotic.


Ich, also known as white spot disease, is a common protozoan infection that affects many fish species, including guppies. Symptoms include white spots on the body and fins, lethargy, appetite loss, and rapid breathing.

Ich can be treated with a combination of salt and a commercial medication, such as Rid-Ich or Quick Cure. Be sure to follow the instructions carefully when administering the medication, and monitor your guppies for any signs of stress during treatment.

Health Issue

Symptoms or Causes

Ich is a very common disease that’s caused by an aquatic protozoan parasite. 
Fish infected with Ich develop a sprinkling of tiny white spots on their fins, gill covers, and bodies. They also flash against the gravel and other solid objects in the aquarium.

Suggested Action

Raise the water temperature to 82o F for three days. Use an OTC  White Spot Disease medication to treat the tank.

Health Issue


Symptoms or Causes

Flukes is the term used to describe various types of external fish parasites. These macroparasites can often be seen with the naked eye attached to the fish’s skin or gills.

Suggested Action

Treat the fish tank with an OTC antiparasitic medication.

Health Issue

Fungal infections

Symptoms or Causes

White fluffy growths on the fish’s body, mouth, and head.

Suggested Action

Quarantine infected fish, and treat with an antifungal medication.

Health Issue

Bacterial infections

Symptoms or Causes

Sores and ulcers on the body and head, ragged, bloody fins.

Suggested Action

Treat the tank with OTC antibacterial treatment.


Choosing Your Breeding Pair

Many first-time guppy breeders assume they must stick to specific guppy strains to get high-quality offspring. However, this isn’t necessarily the case! Adult orange guppy males and females can produce attractive fry of any color combination and pattern. So, if you want to experiment with cross-breeding different color genes and tail fin varieties, go for it.

Be that as it may, it makes sense to opt for healthy parents with good body color formation. Not only will this increase the ability of offspring to live long, healthy lives, but it will also help ensure you get the best-looking fry. Generally speaking, brightly-colored guppies will be perceived as more attractive than those with subtle tints of color.

Despite these general rules of thumb, the attractiveness of offspring will still depend heavily on luck and chance. Choosing your breeding stock based on body color and pattern is a great start, but there’s no guarantee that you’ll get the exact combination of traits you desire. Ultimately, the best way to ensure a good outcome is to simply enjoy the surprise!

Caring For Your Pregnant Guppies

Once you’ve handpicked your breeding stock, it’s time to relocate them to a breeding tank. We recommend a ratio of one male to three female guppies, and at least 10 gallons of space.

The breeding tank should feature a sponge filter to keep the water clean, as well as plenty of aquatic plants and hiding places. For the duration of the gestation period, pregnant female guppies will need plenty of hiding spots to retreat to when they feel threatened.

Once the fry begins to emerge, it’s essential to keep up with tank maintenance. Perform regular water changes and clean the filter every week or so. This will help ensure that your baby guppies have access to clean and oxygen-rich water during the first few weeks of their lives.
