Are Guppies Freshwater Fish? (Complete Answered) By Petsbent

You’ve come to the correct site if you’re wondering whether guppies are freshwater fish.

Guppies are fish that live in freshwater. They are tropical fish because they live in a tropical environment. Guppies may be found all around the globe (except Antarctica). They’re also one of the most common aquarium fish.

Let’s take a closer look at why guppies are known as freshwater fish.

Why are guppies freshwater fish By Nature?

Guppies are freshwater fish since they live in freshwater naturally.
They are more often found in minor streams and ponds, rather than in deep or fast-flowing rivers. Though guppies are most often found in freshwater, they may also be found in brackish water.

The Guppies can even withstand salty saltiness! In fact, many saltwater aquarium owners utilize guppies to start their tank’s fish-in cycle. Guppies can handle a broad variety of water conditions, as you can see, which is one of the reasons they are found all over the globe. They can be found in practically every freshwater region on the planet!

In an aquarium, what sort of water do guppies require?

Guppies are found in freshwater habitats in their native habitat, as you already know.Let’s look at the additional water parameters you’ll need to make your guppies happy in your aquarium.

1. The temperature should be between 72°F and 78°F (22°C and 25°C).

In their native habitat, guppies may be found in tropical areas. The temperature in a tropical setting is normally higher, about 64 degrees Fahrenheit.

As a result, the temperature in your fish tank should be warmer, preferably between 72° and 78°F (22° C and 25° C), to provide a perfect habitat for your guppies. One of the 11 things you can do to keep your guppies happy and healthy is to maintain the appropriate temperature.

Guppies can now withstand temperatures as low as 72°F and as high as 78°F. However, this may have an impact on their pace of growth. Guppies, for example, will develop slower and will likely never reach maturity if the water temperature is below 72°F.On the other side, if the water temperature in your fish tank exceeds 78°F, the guppies will develop too quickly, perhaps shortening their lives.

As a result, a water temperature of 72° to 78°F (22° C to 25° C) is ideal. Guppies will develop normally in this water temperature, meaning they will reach maturity and live longer. Using an aquarium water thermometer, you can simply keep track of the temperature in your fish tank. An aquarium water heater may be used to keep the temperature within the optimal range. It features an adjustable thermostat, so you can simply keep the temperature where you want it.

2. A pH of 7 to 7.2

Guppies can handle a broad variety of pH levels in their water. They can survive pH levels ranging from 5.5 to 8.5. Guppies, on the other hand, like a pH range of 7 to 7.2. Using an aquarium water test kit, you can quickly check the pH of your aquarium water. It’s a liquid-based test kit, therefore it’s rather precise. Furthermore, it is a widely used test kit.

How can the pH of aquarium water be raised?

If the pH in your aquarium water is lower than 7, you may use any of the ways listed below to raise the pH in your aquarium water after testing it.

1. Making use of baking soda

Increasing the pH of aquarium water using baking soda is a frequent method. To raise the pH of your fish tank water, use roughly one tablespoon of baking soda per 5 gallons of water. If you have a 10-gallon fish tank, for example, you’ll need two teaspoons of baking soda to raise the pH.

Remove all occupants from your fish tank, including your guppy fish and/or any other fish, and place them in a different tank before adding the baking soda. After you’ve added the baking soda, you should test the water in your aquarium using an aquarium water test kit. You may now return all of the fish to your fish tank after the pH has been increased to 7.

2. Fill your tank with crushed coral.

Crushed coral may also be added to your aquarium to raise the pH of the water. Crushed coral may be mixed together with your gravel or added directly to your filter. Once you’ve placed the crushed coral in your aquarium, it will gradually disintegrate in your fish tank.

If the pH of your aquarium water is too low, the crushed coral will dissolve more quickly in it. The crushed coral, on the other hand, will disintegrate slowly if the pH of your aquarium water is too high.

How to bring the pH of your aquarium water down to a more manageable level

If the pH of your aquarium water is higher than 7.3 after testing it, you may use one of the following techniques to reduce the pH. You can lower the pH of your aquarium water by adding natural driftwood to it. Keep in mind that if you have a big aquarium, you’ll need a lot of natural driftwood to bring down the pH.

You may reduce the pH of your aquarium water by adding peat moss to your aquarium filter.
Using a reverse osmosis water filter to decrease the pH of your aquarium water is a costly choice. Pesticides, heavy metals, and arsenic will all be removed from the water by the RO water purifier.

Guppies, like any other fish, need to be dissolved oxygen to exist in a fish tank.

There are various methods for increasing and maintaining oxygen levels in your fish tank. You could, for example, put some real aquarium plants in your fish tank. During the day, the living plants will emit oxygen.

You may also add an air pump to your fish tank to ensure that it is fully oxygenated at all times. The air pump will cause water agitation on the surface of your fish tank’s water, which will aid in oxygenation.
