Can Guppies And Goldfish Live Together?

Do you know that if your water is not in the desired PH range as per your fish, it can cause some problems like Algae Growth, Coral Growth, damage to the health of your fish, etc. We would highly recommend getting this API Water Testing Kit on Amazon.com, so you’re always aware of the pH level of your aquarium.

Goldfish is a cold water species and is ubiquitous. They are generally found in ponds, reservoirs, and freshwater habitats. They are the most common aquarium pets because they do not need much maintenance. 

There are two common types of goldfish– the normal one and the fancy one. Compared with the normal goldfish, the fancy one needs warm water to survive. So, if you want to pet fancy goldfish, you must not keep it at a temperature lower than suggested. 

Generally, goldfish require a water temperature between 68° to 74° F. While this fish species can survive at a temperature lower or higher than the suggested, it’s advised not to change the temperature quickly because then it might send a shock to them. And this can kill them. 

On the other hand, guppies are tropical freshwater fish that are inexpensive to take care of. Probably that’s why guppies are other popular aquarium fish that people like to keep. 

Beginners are often advised to keep guppies because they are easy to take care of. But the thing with guppies is that they cannot be housed with every fish as they are so small. So, it’s essential to check the compatibility before keeping them with others in a tank. 

Short Answer 

As you know about both the fish species, you might be wondering whether it’s possible to keep guppies and goldfish together. So, the answer is yes. 

One of the biggest reasons guppies and goldfish can live together is that both are highly calm fish species. They have peaceful behavior, which means they are less likely to cause trouble.

But while doing so, you need to be careful because goldfish can grow bigger than guppies. Thus, there is a potential risk of guppies being eaten by them. 

Also, you might need to keep an eye on the fish tank because goldfish are likely to eat the guppies fry. And since guppies can reach sexual maturity in just three months, you should try to create friendly living conditions for them. 

Here are two ways you can save the guppy fry from the mature goldfish. 

Separate Tank

First things first, you can remove the pregnant female guppy from the tank and place it in a separate container where it can easily lay eggs without any fear. But remember that it’s a cumbersome process. So, you might need to maintain around two tanks. 

Breeding Box

Another way of helping pregnant guppies to breed safely is by placing them in the breeding box. You can do this just before it’s about to lay eggs. This way, the guppy fry will be protected from the mature goldfish. 

Keeping Guppy Fish with Goldfish in the Same Tank 

As you have already read, guppies and goldfish can live in the same tank, but a few things need your attention. 

When you keep guppies and goldfish together, you must set a better water temperature that the fish can easily handle without falling sick. Besides this, there are a few other things that you need to consider while keeping guppies and goldfish together. 

Goldfish Grow Way Too Big

Indeed, goldfish are of different types, but all of them grow bigger than guppies. The minimum length a fancy guppy can grow is around 6 inches, which is 15 cm. Similarly, the maximum length a normal goldfish can grow is 30 cm. 

When goldfish are small, they don’t create a problem. But when goldfish start growing bigger, they might see small guppies as tasty snacks, further creating a deadly living condition for them.  

Guppies Are Fin Nippers

Another thing that does not work in their favor is that guppies like to stay in the group. On the other hand, goldfish do not like to be in crowds as they are calm. You can, however, solve this issue by having a bigger tank.

Feeding Can Become A Problem 

While feeding the fish, you are likely to encounter another problem. That’s because goldfish are greedy eaters. So, wherever you put anything inside the tank, they will try to claim it as their own. Thus, there does not remain enough food for guppies. 

Sickness And Disease 

It’s normal for fish to fall sick when the temperature rises or falls below their tolerance level. If this happens, guppies will struggle to survive in colder water, and in warm water, goldfish will have a problem. 

So, you see, making goldfish and guppies live together is a little difficult. But if you are determined, you can make it happen. And when you keep these two fish together, you must always keep an eye on them.

How Many Guppies Can You Keep With Goldfish? 

To keep guppies and goldfish happily together, you need to get a big tank to make the fish feel safe. At a minimum, the fish tank should hold around 20 gallons of water. This way, three guppies and one goldfish can live together. 

How Many Guppies Can You Keep With Goldfish

If you are planning on adding more goldfish to the tank, increase the size of the tank and bring one that can hold around 30 gallons of water. However, if you want to increase the number of guppies, you can increase the size of the tank by two gallons. Also, if you only have space for keeping a tank that can hold 10 gallons of water, you can keep two small goldfish.

While housing these fish together, you need to remember that the number of goldfish should always be less than guppies. That’s because goldfish can grow double the size of guppies, which can be dangerous. 

If goldfish grow too big, then it’s advised to remove them. But if you can’t remove them, you must add enough hiding spots. This way, both the fish species can live happily in the same tank.

However, if you are determined, you can keep them together without any issue. To maintain the water temperature, you can add a heater

So, before housing guppies and goldfish together, do quick research on their nature. This way, you can understand how they will react in each other’s presence. And then you can take proper precautions.
