Can you put axolotl and betta fish in the same tank?

Here's why:

* Different Water Parameters: Axolotls need cold water (60-68°F), while bettas prefer warmer water (78-82°F). Trying to find a comfortable temperature for both would be impossible.

* Dietary Needs: Axolotls are carnivores, while bettas are omnivores. You would need to provide separate feeding schedules and make sure the betta doesn't try to eat the axolotl's food.

* Aggressive Behavior: While bettas are known for their fighting nature, even a peaceful betta could see the axolotl as a threat and become aggressive.

* Axolotl Vulnerability: Axolotls have delicate skin and are susceptible to injury. A betta's fins could easily injure an axolotl.

In short, keeping an axolotl and betta in the same tank would be stressful and potentially dangerous for both animals.

If you're interested in keeping both species, you will need to have separate tanks with appropriate water parameters and conditions.
