Can Goldfish Live with Newts

Goldfish are popular aquatic pets known for their beauty and ease of care. Newts, on the other hand, are amphibians that also make interesting pets.

Many people wonder if these two species can live together in the same habitat. In this article, we will explore whether goldfish can coexist with newts and provide insights on how to create a suitable environment for both and shrimps.

Understanding the Needs of Goldfish

Before considering the compatibility of goldfish and newts, it’s crucial to understand the specific requirements of goldfish. Here are some key points to keep in mind:

  1. Aquarium Size: Goldfish grow quite large and require spacious aquariums to thrive. A general rule of thumb is to provide 20 gallons of water per goldfish.
  2. Water Quality: Goldfish produce significant waste, requiring excellent filtration and regular water changes to maintain optimal water quality.
  3. Temperature Range: Goldfish prefer a cooler water temperature, usually between 65-75°F (18-24°C).
  4. Oxygen Levels: Goldfish need ample oxygen in their water, so proper aeration is essential.
  5. Water pH: Goldfish thrive in a neutral pH range of 6.5-7.5.

The Nature of Newts

Newts are semi-aquatic creatures that spend time both in water and on land. They have different care requirements compared to goldfish:

  1. Terrarium Setup: Newts require a terrarium with a land area and a water area. The land area should offer hiding spots and moist substrate, while the water area needs to be deep enough for swimming.
  2. Temperature and Humidity: Newts prefer cooler temperatures and higher humidity levels. The ideal temperature range is 60-70°F (15-21°C), and humidity should be maintained around 70-80%.
  3. Water Quality: Newts are sensitive to poor water quality and require frequent water changes. A good filtration system is essential to keep their aquatic habitat clean.

Compatibility Considerations

While goldfish and newts have different care needs, it is possible to create a suitable environment for both. Here are some factors to consider:

  1. Tank Size: Providing a spacious aquarium is crucial to accommodate both species comfortably. A larger tank reduces territorial disputes and provides enough swimming space.
  2. Divided Habitat: Creating separate areas within the tank allows the newts to have their land area while the goldfish inhabit the water section. A glass divider or a floating platform can be used to separate the two.
  3. Water Parameters: Ensure that the water parameters meet the needs of both species. Maintaining a neutral pH and a cooler temperature range benefits both goldfish and newts.
  4. Filtration System: A powerful filtration system is necessary to handle the waste generated by goldfish. Additionally, it is important to regularly monitor water quality and conduct water changes as needed.
  5. Compatibility Monitoring: Always closely observe the interactions between the goldfish and newts. If any signs of aggression or stress are observed, it may be best to separate them permanently.

Potential Challenges and Risks

While the coexistence of goldfish and newts is possible, it’s important to be aware of potential challenges:

  1. Competition for Food: Goldfish are notorious for being voracious eaters and may outcompete newts for food. Ensure that both species receive adequate nutrition by providing separate feeding areas or feeding them at different times.
  2. Water Parameters: Maintaining suitable water conditions for both species can be challenging. Regular monitoring and adjustments may be required to meet the specific needs of each.
  3. Injury Risks: Newts may be at risk of injury from goldfish, especially if the goldfish are larger and more aggressive. It’s crucial to choose goldfish breeds known for their peaceful temperament to minimize this risk.


In conclusion, while it is possible to keep goldfish and newts together, it requires careful consideration and proper setup. Providing a spacious tank, dividing the habitat, monitoring water parameters, and closely observing their interactions are all essential. Remember to prioritize the well-being and specific needs of each species to ensure they can coexist harmoniously. By following these guidelines, you can create a captivating aquatic habitat that accommodates both goldfish and newts.

3. Water Temperature: Finding a temperature range that is suitable for both goldfish and newts can be challenging. It’s important to strike a balance between the preferred temperatures of both species. A range of 65-70°F (18-21°C) can work for both, although it may not be optimal for either species.
4. Water Quality: Maintaining excellent water quality is essential for the health of both goldfish and newts. Regular water changes, proper filtration, and monitoring water parameters such as pH and ammonia levels are crucial.
