Dumbo Ear Guppy Tank Setup

Though Dumbo Ear Guppy is not fussy eaters and can do well in different water conditions, they still need a clean tank to stay healthy - just like any other fish. So if you are a novice fish keeper, it's best to start with a smaller tank and work your way up.

Here are some tips for setting up a Dumbo Ear Guppy tank:

Tank Size

A minimum of 5 gallons is necessary for Dumbo Ear Guppy, however, more than a handful will require a larger tank. A larger tank has plenty of advantages like space for the fish to move around and little water quality issues.

Now, If you want your aquarium to have various kinds of fish, remember their size and needs while picking a tank size.

Water Conditions

Although the Dumbo Ear Guppy can survive in a wide range of conditions, it is important to maintain them at an appropriate level in order for them to fully develop. The temperature at which Dumbo Ear Guppy thrive is between 72-80 degrees Fahrenheit. If at all feasible, try to avoid sudden temperature variations since they are stressful for fish.

To ensure the best environment for your Full Dumbo Ear Guppy, maintain a water salinity of 6.0 to 8.0 and hardness at KH 8-12. Adhering to these parameters will allow your fish to thrive and show their beautiful colors.

Ammonia, Nitrites, and Nitrates should all be at 0 ppm. If any of these levels rise, it can harm or even kill your fish. To maintain 0 ppm for all 3, do a 30-50% water change every week and vacuum the gravel to remove debris that can rot and release these toxins.

Dumbo Ear Guppy


Your filter should be able to turn over the entire volume of your tank at least 3 times per hour. A canister or hang-on back filter is best for this.

For a 5-gallon tank, a filter that can turn over 30-60 gallons per hour is necessary.

If you have a larger tank, you'll need a filter that can turn over the entire volume of your tank at least 3 times per hour.


It's not essential to provide special decorations for Dumbo Ear Guppy, although if you want to make your aquarium more appealing, there are several choices. Below are some recommendations:


Dumbo Ear Guppies do not require live plants, but they do benefit from them. Plants aid in the maintenance of clean water and offer hiding places for fish. Live plants also enhance the oxygen level in the water. The following are some excellent plant choices for Dumbo Ear Guppy tanks:

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

If you're finding it difficult to locate these plants in your area, don't worry – artificial plants are a great alternative. Be sure to select fish-safe plants that are made from non-toxic materials, and give them a good wash before adding them to the tank.

Rocks and Driftwood

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.


Although Dumbo Ear Guppy doesn't need a special type of substrate, they do need some sort of foundation to keep its plants in place. A gravel base works well for these fish. Just be sure to pick rocks that are small enough so the guppy won't accidentally swallow them. As long as you maintain a sterile environment and refrain from placing anything harmful in the tank with your guppy, they should thrive!

If you want live plants in your aquarium, you need to add a nutrient-dense substrate. A good choice for live plants is an aquarium soil substrate.


Dumbo Ear Guppy doesn't require any special lighting, but if you want to bring out their colors, you can use full-spectrum LEDs. These will also help your live plants to grow.

Tank Maintenance

Proper tank maintenance is essential for the health and well-being of your Dumbo Ear Guppy. Be sure to do the following:

  • Perform regular water changes: At least once a week, you should remove 10-15% of the water from your tank and replace it with fresh, treated water. This will help to keep the water clean and free of toxins.
  • Vacuum the gravel: Every other week, vacuum the gravel in your tank to remove any debris that has accumulated. This will also help to keep the water quality high.
  • Clean the filter: Be sure to clean your filter regularly. This will help to remove any toxins or waste that has accumulated in the filter media.
  • Trim the plants: If you have plants in your tank, you may need to trim them back from time to time. This will help to keep the plants healthy and prevent them from taking over the tank.

While performing tank maintenance, please keep the following things in mind:

  • Never remove all of the water from your tank. This will cause your fish to go into shock and may even kill them.
  • Be sure to use a gravel vacuum that is designed for aquariums. These vacuums are gentle and won't damage your fish or plants.
  • When cleaning your filter, be sure to rinse the filter media in old tank water. This will help to remove any toxins that may be present in the water.
  • When trimming your plants, be sure to use sharp scissors. This will help to prevent damage to the plant.
  • While changing the water, use a water conditioner to remove any toxins that may be present in the tap water.

Dumbo Ear Guppy Diet

Dumbo Ear Guppy are omnivores that will consume a wide range of fish foods. flakes, pellets, frozen, and live food is all acceptable.

Here are some good food choices for Dumbo Ear Guppy:

  • Flakes or pellets: A Dumbo Ear Guppy's diet should consist of high-quality flakes or pellets as they are easy to digest and contain all the nutrients a guppy needs. Be wary of foods with lots of fillers or artificial colors as these can harm your fish.
  • Live food: By adding live food to your Dumbo Ear Guppy's diet, you are increasing the nutrient value they are receiving. Live food often contains more nutrients than pellets or flakes and can help keep your fish healthy overall. Some good examples of live foods include brine shrimp, daphnia, blackworms, etc.
  • Frozen food: Live food is more expensive to maintain, and frozen food is a viable substitute. It's more convenient and simpler to store than live food. Before feeding your fish, ensure that the meal has been thawed out properly.
  • Vegetables: Dumbo Ear Guppy also enjoys vegetables. Blanched spinach, zucchini, and peas are all good options. To ensure that uneaten crops do not decay and pollute the water, remove any remaining veggies from the tank.

Dumbo Ear Guppy Diseases 

Although Dumbo Ear Guppy is tough, there are some diseases from which they cannot escape.

These include:


The fish's skin begins to develop tiny white spots, which is known as ich. It's caused by an ectoparasite (ciliate protozoan Ichthyophthirius multifiliis), making it extremely simple to detect. The fish begin rubbing their skin against rocks, plant leaves, or other objects in the aquarium. They can also lose interest in food. You'll notice little white dots on the fish's skin and fins. To cure ich, you'll need to raise the water temperature and perform a partial water change.

Follow the following:

Check the temperature of the water on a daily basis to ensure that it does not exceed 80 degrees Fahrenheit. Follow the manufacturer's instructions for adding medication. Add aquarium salt, according to the manufacturer's recommendations, at a rate of 1 teaspoon per gallon. Allow 4-7 days for this phase to run its course before checking on it again. Gradually return the water temperature back to normal over a period of several days or weeks.

Once the ich has been eliminated, it's important to take measures to prevent it from happening again. This includes quarantining new fish before adding them to the tank and keeping the aquarium clean.


The most common form of anemone blenny disease is velvet disease. It's also known as ich, but it's considerably less common to find in aquariums kept by amateurs. A fish with velvet might have tiny golden-colored dots all over its body, making it appear like grains of dust. If you don't take precautions, this condition may quickly spread to every one of your other fish.

Fish keepers often discover problems with a fish's skin too late because the early stages are difficult to detect. A fish's skin is velvet and small dots make it hard to see changes. When the skin starts peeling and there is blood, then owners know something is wrong.

To cure velvet:

Velvets can be treated with copper medication. 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 every other day for at least two weeks.

Fin Rot

Guppies that have rotting fins and tails suffer from a bacterial infection, which causes their fins and tail to appear welded together. This can also be caused by a fungus that develops on nipped fins. In addition, poor water quality and ammonia burns are two additional factors that cause decaying tails.

It is crucial to identify the cause of rotting fins because treatment for bacterial infection or fungus differs. If there is no damage to the fins and tail but they have started rotting, bacteria are most likely the culprit.

If your fish has fin rot, you should isolate it and give it antibiotics. However, if the cause of the fin tail rot is a fungus, then treat it with special medication – always following instructions on said packaging. In order to avoid "ammonia burns", be sure to provide high-quality water for your fish.


Guppies are the most common hosts for the protozoan parasite, which can infect them. Although other fish may become sick as well, guppies are by far the most prevalent host for this little creature. The parasite latches onto the fish's skin and works its way into the fish's body via its muscles until it reaches circulation.

When water quality is bad, this worm generally develops in shoddy tanks.

If your fish has protozoan, heat the water in their tank to keep the temperature stable. This can be treated with Malachite Green or Formalin at early stages, and copper medications like Seachem Cupramine should be used for more severe cases. After treatment, change 50-70% of the water.

Water quality is important for the prevention of all these diseases. Add an ammonia remover to your guppy tank and change 20-30% of the water every week. This will help to keep the levels of ammonia and nitrites low, which will create a healthier environment for your fish.


This infection, which appears to be fungal but is actually caused by bacteria, typically grows as a large white sludge on the fish's mouth or midsection. The colony of bacteria slowly paralyzes their muscle and patients have difficulty swimming and lose their appetite.

Guppies are highly susceptible to the disease and can become infected if they come into direct contact with an affected guppy. The illness is highly transmissible and predominantly affects female guppies, although male guppies can also be ill. If the infection isn't treated, it has the potential to eradicate the tank's entire fish population.

The best way to fight Columnaris and mouth fungus is to immediately begin the treatment process once any symptoms become apparent. Two popular drugs used for this purpose are Maracyn and Formalin. In addition, increasing the salt content in your aquarium can also be helpful: do a 50% water change and add one teaspoon of salt per gallon every day for three days after the initial water change.

Only remove the salt from your fish tank once it has completely healed. In addition, a 30-minute potassium permanganate (KMnO4) bath can cure Columnaris; however, use this treatment with caution. Potassium permanganate is a powerful oxidizing agent and exceeding 10mg/l in the bath risks burning your fish.


Lethargy is the most frequent sign of unhealthy water conditions. If your guppy has no energy, and isn't swimming or eating, poor water quality is likely the cause.

Other symptoms include:

  • Gasping for air at the surface of the water
  • Clamped fins (when the fish's fins are held close to their body)
  • Slimy or discolored skin
  • White spots
  • Fungus on the skin or fins (Saprolegnia)
  • Fin and tail rot
  • Red patches on the skin
  • Bulging eyes
  • neurological disorders such as swimming in circles or upside down

If you notice any of these symptoms, it's important to take action immediately in order to save your fish's life.


The following are some tips that will help you prevent your guppy from getting sick:

  • Keep the water in their tank clean and free of ammonia and nitrates.
  • Do a partial water change every week and clean the gravel at the bottom of their tank.
  • Don't overfeed your fish – only give them as much food as they can eat in a few minutes.
  • Don't put fish of different sizes together in the same tank.
  • Avoid putting stressors in their environments, such as bright lights or loud noises.
  • Keep their tank at a stable temperature between 72-82 degrees Fahrenheit.

Dumbo Ear Guppy Breeding

It's extremely important to understand that guppies breed quickly and can overrun a tank if they are not monitored. Guppies are livebearers, meaning they give birth to living fry instead of laying eggs.

These steps will show you how to breed guppies:

  • Before you start breeding guppies, make sure to pick a male and female that would make good parents. The male should have large fins that are colorful, and the female should be plump with a gravid spot. It's best to choose young guppies because they're more likely to produce healthy offspring. If you want assurance of reproduction, then it is ideal to select three or four adolescent pairs.
  • Follow these easy steps to set up a breeding tank for guppies. First, you'll need at least a 10-gallon tank. The female guppy will also need plenty of hiding places; you can use live or plastic plants for this purpose. In addition, be sure to have a fine-mesh net on hand to catch the fry (baby fish) when they're born. Finally, set the temperature of the breeding tank between 75-80 degrees Fahrenheit prior to adding any fish."
  • After the breeding tank is prepared and ready, place the guppies inside to get used to their new surroundings. Give them some time to adjust for about an hour before letting them have free range in the tank.
  • In order to keep your fry healthy, you'll need to feed them several times a day. It's best to do this for at least four hours each time. You can give them live baby brine shrimp or specialized fry food. Once they're about two weeks old, you can start feeding them adult guppy food.
  • Make sure to clean the fry tank weekly in order to prevent illness. This involves changing out the water and removing uneaten food from the previous week. After four weeks have passed, your trout will be big enough to move into a larger aquarium.
