Can you put a betta fish in tank with goldfish?

Reasons why:

* Temperature differences: Bettas prefer warmer water temperatures (78-82°F), while goldfish prefer cooler water (68-72°F). Maintaining a suitable temperature for both species is challenging.

* Water conditions: Bettas require soft, slightly acidic water, while goldfish tolerate harder water with a higher pH.

* Feeding: Bettas are carnivores and eat live or frozen foods, while goldfish are omnivores and prefer flakes or pellets.

* Fin-nipping: Goldfish are known to nibble on the fins of other fish, which can be harmful to bettas.

* Aggression: Goldfish can be aggressive towards other fish, especially smaller ones like bettas.

Consequences of putting a betta with goldfish:

* Stress and illness: The temperature and water quality differences can cause stress and illness in both species.

* Injuries: Fin-nipping and aggression from the goldfish can lead to injuries and death for the betta.

* Shortened lifespan: The stress and poor water conditions can shorten the lifespan of both the betta and the goldfish.

Conclusion:

It is highly recommended to keep bettas and goldfish in separate tanks to ensure their health and well-being.
