However, choosing the right companions for your goldfish requires careful consideration. Here, we provide guidelines and recommendations for selecting compatible tank mates that will thrive alongside your goldfish.

Goldfish Tankmates: What Other Fish can Live with Goldfish?

General Guidelines for Goldfish Tank Mates

When selecting tank mates for goldfish, keep these principles in mind:


  1. Avoid Aggressive Fish: Goldfish are peaceful creatures. Aggressive species, such as certain barbs or African cichlids, may harm or stress goldfish.

  2. Consider Swimming Speed: Common goldfish are swift, while fancy goldfish are slower and may be bullied by faster tank mates.

  3. Size Matters: Avoid small fish that can fit into a goldfish’s mouth or spiny fish that can cause injury if ingested.

  4. Environmental Compatibility: Goldfish prefer cooler water temperatures (50-70°F) and diets that suit their specific nutritional needs. Ensure that tank mates can thrive under similar conditions.

Top 10 Compatible Tank Mates for Goldfish

1. Hillstream Loach: These unique fish resemble miniature stingrays and are adept at clinging to surfaces. They thrive in cooler temperatures and help keep the tank clean by eating algae and food scraps.

2. Brochis multiradiatus: Also known as the hog-nosed catfish, these large, peaceful bottom dwellers reach up to 4 inches in size and are excellent at scavenging, making them suitable companions for goldfish.

3. Dojo Loach: Resembling foot-long hot dogs, dojo loaches are friendly, active, and thrive in cold water. Their playful nature makes them a popular choice for goldfish tanks.

4. Bristlenose Pleco: These smaller plecos are excellent algae eaters. To prevent them from sucking on a goldfish’s slime coat, ensure they are well-fed with sinking wafers, bloodworms, and other suitable foods.

5. Rubbernose Pleco: Similar to bristlenose plecos but without the bristles, these peaceful fish grow to about 5-6 inches and help keep the tank clean.

6. White Cloud Mountain Minnows: These cold-water fish are fast, schooling species that add lively activity to the tank. Avoid longfin varieties, as their extended fins can make them more susceptible to being caught by goldfish.

7. Ricefish: Available in various colors, ricefish are beautiful and hardy, thriving in cooler temperatures. They breed easily and add vibrancy to goldfish tanks.

8. Hoplo Catfish: Growing up to 5-6 inches, hoplo catfish are docile and continuously scavenge for food with their long whiskers. They are diurnal, making them compatible with goldfish’s feeding schedule.

9. Variatus Platy: These livebearers come in a variety of colors and thrive in cooler waters. Their frequent reproduction provides goldfish with a natural food source, helping control the platy population.

10. Longfin Rosy Barbs: These peaceful barbs can coexist with goldfish if kept in larger schools. Their long fins slow them down, ensuring fair competition for food with goldfish.

By following these guidelines, you can create a harmonious and diverse aquarium that benefits both your goldfish and their tank mates. Always consider the temperature, diet, pH, aggression level, and size compatibility when selecting new additions to your goldfish tank.


By following these guidelines and carefully selecting compatible tank mates, you can create a vibrant and harmonious environment for your goldfish. Enjoy the beauty and diversity of a well-balanced aquarium!
