Tank conditions for fish to live with goldfish
Fishkeeping can be a challenging hobby to get into. You need to know many things to keep your fish healthy and happy. Many people give up on fishkeeping because they think it’s too hard or needs more information.
We’re here to help. We’ve compiled a list of the primary tank conditions for fish to live with goldfish. By following these guidelines, you’ll be well on your way to creating a healthy and happy home for your fish.
Live In the Same Temperature Range
Goldfish prefer water temperatures of around 65-75°F (18-24°C). This temperature range is a comfortable one for most other fish.
However, some species may need slightly cooler or warmer temperatures—so make sure to research the specific needs of your tank mates before adding them to the goldfish aquarium.
Fish That Are Too Big to Get Eaten
Goldfish can grow up to 12 inches (30 cm) in length and have a large appetite. So, selecting tank mates that are too big for hungry and curious goldfish to swallow is crucial.
This doesn’t mean you need to fill your aquarium only with large species—but do avoid any fish smaller than 1 inch (2.5 cm).
Choose Fish That Have a Peaceful Temperament
Goldfish can be territorial, so avoiding any aggressive fish is best. Select species that are more docile and won’t pick fights with each other or the goldfish.
It’s also worth adding some peaceful freshwater fish for your goldfish to interact with—as this can reduce their aggression toward other tank mates.
Matching Activity Levels
Goldfish have a slow and steady swimming style, so it’s best to choose fish that swim at similar speeds. Too many speedy species can intimidate the goldfish and cause them stress.
For example, goldfish are a great match with other slower-moving fish, like Corydoras catfish or gouramis. On the other hand, if you want to add some zest to your tank, you could try species like guppies or platies.

When kept with goldfish, however, they can be susceptible to being eaten or having their shells nibbled away by the larger fish.

17. Bristlenose Pleco Catfish (Ancistrus sp.)
Bristlenose Pleco (Ancistrus sp.) are peaceful and hardy addition to freshwater tanks. They are an excellent choice for goldfish tanks, as the plecos need a small area of vegetative cover, while goldfish prefer open water.
This combination provides the best of both worlds and makes it easier for aquarists to keep a balanced tank environment.
The Bristlenose Plecos can reach up to 6 inches in length and prefers temperatures between 72-78 degrees Fahrenheit with a pH level around 6-7. These fish require frequent feedings of sinking tablets, blanched vegetables, algae wafers, or occasional live foods such as brine shrimp or bloodworms.

Bamboo shrimp (Extra Choice)
Bamboo shrimp, also known as Wood or Vampire Shrimp, can make a great goldfish tank mate. They are hardy and peaceful creatures that help keep the tank clean by sifting through debris in search of food.
Bamboo shrimps require frequent water changes and may become shy if not correctly cared for, so they should be kept in an aquarium with ample swimming space and plenty of hiding spots.

Can Goldfish Live with Tropical Fish?
Can you mix goldfish with tropical fish? Goldfish are coldwater fish, and tropical fish require warm water temperatures, so they should generally not be kept together.
However, you can keep both types of fish in the same tank if you provide the appropriate temperature range for each species and use an effective filtration system to maintain good water quality.
In addition, stick with similar fish in size and temperament to prevent aggression. Proper care makes it possible to keep both goldfish and tropical fish successfully in the same aquarium!
Can Goldfish Live with Other Goldfish?
Goldfish can be kept together with other goldfish if you provide enough room for each fish to swim.

In addition, when keeping multiple goldfish in the same tank, ensure adequate filtration and regular water changes to maintain a healthy environment.
Goldfish Tank Size
The larger the goldfish tank size, the better; a single fancy goldfish should have at least a 10-gallon aquarium, and each additional fish requires an extra gallon of water for them to live comfortably.
You will need even more space for common goldfish – at least 20 gallons per fish. With adequate space, you can provide plenty of hiding places and room for the goldfish to swim around.
In addition, having a larger tank will make it easier to maintain good water quality with proper filtration and regular water changes.
Keeping your goldfish in an appropriately sized aquarium will help keep them healthy and happy!

Can Tetras Live with Goldfish?
Goldfish and tetras in same tank? While the two species can coexist, providing each one with its ideal environment is essential.
Tetras require warmer water temperatures than goldfish and like to school together in groups of six or more. Depending on the size and temperament of your goldfish, they may be aggressive towards schooling tetras and disrupt the group dynamic.
In addition, tetras are much smaller than goldfish and require frequent water changes to stay healthy, so a larger aquarium is necessary when considering this community. With proper preparation, you can enjoy a peaceful tank full of goldfish and tetras!
Do Goldfish Need 2 or 3?
It is best to keep at least two goldfish in a tank, as they are social animals that need companionship from their species. Keeping more than two goldfish in the same tank also helps spread out aggression and other forms of stress.
Additionally, having multiple fish allows them to thrive in a larger environment, whereas having only one fish can cause stress due to being confined to a limited space.
Moreover, you should ensure the tank has plenty of rocks, plants, or decorations, so your goldfish have enough places to hide and explore.
Will Goldfish Survive in My Fish Tank?
The short answer is yes! Goldfish are very hardy fish that can survive in various water conditions.
However, to ensure your goldfish thrive and remain healthy in their new home, you must provide the tank is cycled correctly and has the proper temperature range for each species.
You must also use a good filter and regularly change the water to keep the aquarium clean and clear. With these basic requirements in place, you can be sure that your goldfish will have a happy home!
Can You Put Catfish with Goldfish?
With their small adult size under 4 inches long, Corydoras catfish can be ideal companions for peaceful varieties of fancy little goldfish.
When adding catfish to a goldfish tank, you should ensure the water temperature is suitable for both species and provide plenty of hiding places so that they can coexist peacefully.
It’s also important to remember that corydoras enjoy having their own company and should be added to groups of at least three or four. With the right conditions and tankmates, a goldfish and corydoras aquarium can create a beautiful display.
