Ideal Water Parameters of Goldfish and Guppy Fish

Guppy fish are best adapted to temperature ranges between 73-80 degrees. Guppy fish can be found in water at pH levels of 6.7 to 7.8. Goldfish can be found at temperatures of 68 – 74 degrees Celsius. Goldfish live at a pH of 7.4.

When setting up a fish tank for goldfish and guppies, it is vital to ensure correct pH levels. While both species can survive in slightly different pH ranges, having a consistent level between 6.7-7.4 will be best for both species.

Tank set-up for Guppies and Goldfish

The tanks should be larger, depending on how big you need to house Guppies and Goldfish. Moreover, larger tanks will help keep the water tank temperature stable.

Change water temperature and pH at common values. Water temperatures are among the most common failures in maintaining goldfish and guppies in the same aquarium. The temperature range between Guppies and Goldfish can be established easily and quickly.

During winter, temperatures of 70 – 75 degrees (21 and 24-36 degrees) can be regulated at seven ppm. Guppie and goldfish are happy if they have an optimal balance. The heating unit needs control to maintain a constant temperature.

Invest in a Bigger Aquarium

Larger aquariums will accommodate fish and guppies more quickly than smaller ones. Both species can move freely. Likewise, water conditions remain stable in a large tank.

Include Plants, Rocks, and gravel.

These items protect the Guppies and Goldfish. Besides, they offer hiding spots when any of them feel harassed.

Provide Proper Filtration

When two or more species live together, the filter must be strong enough to keep the water clean. Installing a powerful filter with adequate carbon is essential.

Set the Right Water Temperature

Goldfishes are generally capable of sustaining a lower water temperature. That’sThat’s a good reason. Usually, the goldfish in the aquarium do not require heating or filtration. However, you must be sure the temperature of the water will stay constant.

Add Live aquatic plants to your guppy-goldfish tank.

Live aquatic plants help fish feel safe and secure, add oxygen to the environment, promote filtration, and reduce nitrates.

Can Goldfish Live with Mollies?

Can Molly and goldfish live together? Keeping Goldfish and Mollies together in the same fish tank is not recommended. Goldfish thrive best in cool and slightly acidic, whereas Mollies prefer warm water that is more alkaline.

In addition, they are pretty different in size—Goldfish can reach 4-6 inches while Mollies typically stay around 2-3 inches–which can cause a problem regarding food competition.

Therefore, although possible, keeping these two species together can be challenging and should not be attempted by beginners or those with little experience in fish care.

Can a Guppy Mate with a Goldfish?

No, guppies and goldfish are not truly compatible. Though they can live in the same tank, they have different requirements for water temperature, pH levels, and oxygen levels.

Additionally, their body sizes and anatomy differ significantly – without special care to facilitate mating between the two species, it would be difficult for them to breed together successfully.

Can Goldfish and Guppies Eat the Same Food?

Yes, guppies and goldfish can both eat the same food. Generally speaking, they are omnivores that sometimes feed on small crustaceans or insects.

In captivity, a variety of foods can be fed to them, such as flakes, pellets, mosquito larvae, live foods (bloodworms and brine shrimp), freeze-dried foods (tubifex worms), and even blanched vegetables like zucchini. Mixing different types of food for more balanced nutrition is also possible.

However, it is better to avoid overfeeding either species as excesses can lead to health issues such as obesity or digestive problems.

What Fish Can Live with Goldfish?

Fish that can live with goldfish in an aquarium include Zebra Danios, White Cloud Mountain Minnows, Corydoras catfish, Dojo Loach, and Platy.

These fish prefer slightly acidic water pH levels (6.5-7.0) and a temperature range of 68 to 74 °F (20 to 23 °C). Generally speaking, all the species should be similarly sized so that no one gets hurt or intimidated by the larger fish.

The presence of plenty of hiding places is also essential, as well as adequate filtration and regular water changes to keep their water clean and healthy.

These fish get along well with goldfish, but it’s always best to introduce them slowly into the tank while monitoring their interactions. Hence, they form a harmonious community without any issues!

Can Goldfish Live with Tropical Fish?

Although Goldfish and Tropical Fish can cohabitate in an aquarium, it is not recommended due to the differences in their natural habitats.

Goldfish prefer cooler water temperatures (below 70 °F), while tropical fish thrive in warmer waters (75-80°F). The temperature difference can cause stress on both species, making them more susceptible to disease and death.

Additionally, certain tropical fish may become aggressive towards the slower-moving goldfish or take advantage of them as a food source. It is best to separate these two types of fish for their safety and well-being.

Can Guppies Live with Glofish?

No, it’s not a good idea to keep guppies and Glofish together. While both species belong to the same Cyprin genera, they are, in fact, quite different when it comes to their habitat requirements and behavior.

Guppies prefer hard, alkaline water, while goldfish prefer acidic water with high carbon dioxide levels for optimal health. Each other’s behavior can easily stress the two species, so combining them in one tank is rarely a good idea.

What Fish Can Live with Guppies?

Guppies are a popular fish for aquariums, and many other fish species can happily coexist with them. These include Suckermouth Catfish, Cory Catfish, Swordtails, Common Molly, and Platy Fish.

These species need similar environments as guppies regarding water temperature (72-78°F) and pH balance.

So if you’re looking to add some variety to your guppy tank without compromising the well-being of your fish, consider adding some of these other fish species!
