Can goldfish go with guppies out tank temp is 27?

Goldfish and guppies are not ideal tank mates due to their different water temperature requirements. Goldfish prefer cooler waters, between 68-74°F, while guppies prefer warmer water, generally around 75-82°F. At 27°C (80.6°F), the temperature may be too high for the goldfish and too low for the guppies, leading to potential stress and health issues for both species.

Why are Separate Tanks Better?

1. Temperature Requirements: The optimal temperature ranges for goldfish and guppies do not overlap significantly, making it challenging to maintain conditions that are suitable for both species in the same tank.

2. Diet and Feeding Differences: Goldfish are omnivorous and tend to eat more voraciously than guppies. In a shared tank, goldfish may outcompete guppies for food, leaving the guppies malnourished or underfed.

3. Size Differences: Goldfish can grow significantly larger than guppies, potentially leading to aggression and territorial issues as they compete for space and resources.

4. Fin-Nipping: Goldfish are known to be fin nippers, which can cause damage to the delicate guppies fins.

Recommendation:

To ensure the health and well-being of both goldfish and guppies, it is best to house them in separate tanks with appropriate water parameters and environmental conditions tailored to their specific needs.
