Can Goldfish Live With Neon Tetra? (No, Is It Risky…)
Goldfish and neon tetras are two of the most popular fish among aquarists. But can they survive in the same tank? Is it safe to keep Goldfish and Neon Tetra together?
Can goldfish and neon tetras live together harmoniously, or will one species dominate the other? Check out the answer below!
No, goldfish and neon tetras cannot live together harmoniously. Goldfish typically need colder temperatures than what is optimal for neon tetras, and the two species have different dietary needs.
Additionally, goldfish tend to be larger in size than neon tetras, so they can easily overpower smaller fish such as tetras or eat their food. For these reasons, it is not recommended to keep goldfish and neon tetras together in the same tank.
In this blog post, I’ll go into more detail about why it is not recommended to keep goldfish and neon tetras together, as well as some tips for successfully keeping them in separate tanks.
Why Can’t They Live Together?
One of the main reasons why goldfish and neon tetras cannot live together is because of their different temperature requirements.
Goldfish prefer cold water, while neon tetras need warm water to survive. Keeping these two species in a tank with an incorrect temperature can have serious consequences for both types of fish.
Another reason why it is not recommended to keep goldfish and neon tetras together is because of their different dietary needs.
Goldfish are omnivores, meaning they will eat both plant and animal material. However, neon tetras are primarily herbivores and require a diet high in vegetable matter.
Finally, the size difference between goldfish and neon tetras can be a problem. Goldfish are larger and more aggressive, so they may eat the food meant for the smaller tetras or even attack them.
This is why it is not recommended to keep goldfish and neon tetras together in the same tank.

What is the Difference Between a Goldfish and a Neon Tetra?
Goldfish and neon tetras are two of the most popular species in the aquarium hobby. Although they share some similarities, there are some distinct differences between them.
One of the main differences between a goldfish and a neon tetra is size. Goldfish generally range from 4-6 inches in length while neon tetras are typically around 1.5-2 inches in size.
Goldfish are also much hardier and can tolerate a wider range of water conditions than neon tetras.
Another difference is the shape of their bodies. Goldfish have rounder, fatter bodies while neon tetras have slender, streamlined profiles. This makes them well-suited for swimming in swift currents.
Goldfish are omnivorous and will consume a wide variety of both meaty and vegetable-based foods. Neon tetras, on the other hand, are primarily herbivores and do best when fed a diet that is mostly vegetarian.
Lastly, goldfish can be kept alone or with other goldfish. Neon tetras, however, do best in a group with at least 6-8 members of the same species. This is because they are schooling fish and like to stay together for safety and comfort.
Overall, while goldfish and neon tetras share some similarities, there are distinct differences between them when it comes to size, body shape, diet, and social behavior.
When choosing fish for your aquarium, it is important to consider these factors in order to ensure that the species you select are compatible with each other and will thrive in their environment.

How Do I Set Up a Goldfish and Neon Tetra Aquarium?
Setting up a goldfish and neon tetra aquarium can seem like an intimidating task, but it doesn’t have to be.
With the right supplies and knowledge of the ideal water parameters for each species, you can easily create a safe and healthy home for both types of fish.
1. Choosing the Right Tank
The first step to creating a goldfish and neon tetra aquarium is to choose the right tank. Goldfish need more space than neon tetras, so it’s important to select an appropriate size for both species.
Most experts recommend at least 30 gallons for keeping goldfish, but larger tanks are even better. That said, you can keep up to five neon tetras in a 10-gallon tank.
When selecting an aquarium, make sure to choose one with a secure lid to prevent any fish from jumping out. Additionally, you will need a filter and heater for the tank.

2. Creating the Ideal Water Parameters
Once the tank is set up and filled with dechlorinated water, it is important to test the water parameters and make any necessary adjustments.
For goldfish, the ideal water temperature is between 10-20°C (50-68°F). The pH should be between 6.5-8.0, KH 4–12 dKH, GH 5-19dGH, ammonia 0ppm, nitrite 0ppm, and nitrate <20ppm.
Neon tetras prefer slightly warmer temperatures of 20-26°C (68-79°F). The ideal pH for them is 5.5-7.5, KH 2–8 dKH, GH 8–14GH, ammonia 0ppm, nitrite 0ppm, and nitrate <10ppm.
3. Adding Decorations and Plants
When setting up the tank, be sure to add plenty of decorations and plants for the fish to explore. Goldfish love caves and hiding spots, so adding some rocks or driftwood can create a fun environment for them.
For the neon tetras, adding plenty of plants is ideal as they provide hiding spots and also act as a food source. Be sure to choose low-light aquatic plants such as java fern or anubias that don’t require intense lighting.
4. Introducing the Fish
Once the tank is set up and the water parameters are ideal, it is time to add the fish. When introducing both types of fish into a tank, it is best to do so gradually.
Start by adding just a few goldfish, and then wait at least 24 hours before adding the neon tetras. This will give them both time to adjust to their new environment and each other.
Now you have everything you need to create a healthy and thriving aquarium for both goldfish and neon tetras!
With the right supplies, knowledge of water parameters, decorations, and cautious introduction of both species, you can easily set up a tank that will be enjoyable for many years.

What Are the Best Tank Mates for Goldfish?
When it comes to setting up a tank for goldfish, there are many different options for tank mates.
Some fish species make great companions, while others can be detrimental to the health of your goldfish. It is important to do your research before introducing any new fish into your tank.
1. Incompatible Tank Mates
There are some species of fish that should never be kept with goldfish. These include any type of tropical fish such as tetras, barbs, guppies, and angelfish.
These fish require warmer water temperatures than goldfish can tolerate, so they will often become stressed or ill in a goldfish tank.
Other fish that should not be kept with goldfish include any type of aggressive species such as cichlids, Oscars, and piranhas. These fish are likely to pick on or even attack the goldfish in the tank.
2. Compatible Tank Mates
There are many species of fish that can be successfully kept with goldfish. These include temperature-tolerant fish such as koi, shubunkin, or weather loaches.
All of these fish require similar water conditions and temperatures to the goldfish.
Other compatible tank mates for goldfish include snails such as Malaysian Trumpet Snails or Pond Snails, or bottom-feeding fish such as Corydoras catfish.
These fish are peaceful and can help keep the tank clean by eating algae and leftover food particles.
3. Tips for Introducing Tank Mates
When introducing any new fish into an established goldfish tank, there are a few things to keep in mind.
First, it is important to slowly acclimate the new fish before releasing it into the tank. This can be done by floating the bag of new fish in the tank for 15-20 minutes and then gradually adding small amounts of tank water to the bag until it is full.
It is also important to make sure that there are plenty of hiding spots and vegetation in the tank. This will give the new fish a place to retreat if they become stressed or intimidated by the existing fish.
Finally, it is important to keep an eye on all of the fish in the tank for at least a few days after introducing any new ones. This will help you monitor their behavior and make sure that they are all getting along.
What Are the Best Tank Mates for Neon Tetra?
The neon tetra is a popular aquarium fish that is small and peaceful. Many aquarists like to keep these colorful fish in their tanks, but it can be difficult to find suitable tank mates for them.
1. Incompatible Tank Mates
Neon tetras should never be kept with large or aggressive species of fish such as cichlids, Oscars, and piranhas. These fish are likely to pick on or even attack the neon tetras in the tank.
In addition, tropical species such as guppies and angelfish should also be avoided because they require warmer water temperatures than neon tetras can tolerate.
2. Compatible Tank Mates
The best tank mates for neon tetras are other small, peaceful species such as danios, rasboras, and White Cloud Mountain Minnows.
These fish require similar water conditions and temperatures to the neon tetra and can provide a great deal of visual interest to the aquarium.
In addition to these small fish, algae-eating species such as snails and bottom-feeding fish can also make good tank mates for neon tetras.
These fish will help keep the tank clean by eating any excess food or algae that accumulate in the tank.

What Are Some Common Problems With Keeping Goldfish and Neon Tetra Together?
Goldfish and neon tetras are two of the most popular aquarium fish in the world. Many people choose to keep them together, but there are some things to consider before doing so.
In this part, I’ll discuss some common problems that can occur when keeping goldfish and neon tetras together.
1. Compatibility
One of the biggest issues with keeping goldfish and neon tetras together is compatibility.
Goldfish are large, active fish that require a lot of space to swim while neon tetras are small, timid fish that prefer to remain close to the bottom of the tank.
Keeping these two species in the same aquarium can lead to a lot of stress and territorial disputes.

2. Water Quality
Another common problem that can occur when keeping goldfish and neon tetras together is poor water quality.
Goldfish are highly sensitive to changes in their environment, so it is important to maintain a stable pH level as well as an acceptable nitrate level.
On the other hand, neon tetras are relatively hardy fish and can tolerate less-than-ideal water conditions.
3. Size Difference
The size difference between goldfish and neon tetras can also cause issues when keeping them together.
Goldfish grow to be much larger than neon tetras, which means they require more food in order to stay healthy.
If not enough food is provided, the smaller neon tetras may not get enough to eat and could eventually starve.
4. Competition for Food
The competition for food can also be a problem when keeping goldfish and neon tetras together. Goldfish are voracious eaters that will consume all of the food in the aquarium if given the chance.
On the other hand, neon tetras are smaller and not as aggressive when it comes to eating. If there is not enough food for both species, the goldfish may end up hogging all of it and leave the neon tetras unable to get any.
