Can glow in the dark guppy fish be same tank as a betta fish?

It is not recommended to keep glow-in-the-dark guppies and a betta fish in the same tank. Here's why:

* Betta fish are aggressive: Betta fish are known for being territorial and aggressive, especially towards other males. They may attack and injure or even kill the guppies, even if the guppies are glow-in-the-dark.

* Guppies are peaceful: Guppies are peaceful and relatively small fish. They are not a match for a betta's aggression and will likely be bullied.

Instead of a betta, consider other peaceful tank mates for glow-in-the-dark guppies, such as:

* Neon tetras: These small, colorful fish are peaceful and compatible with guppies.

* Corydoras catfish: These bottom-dwelling fish are peaceful and help to clean up the tank.

* Ghost shrimp: These shrimp are peaceful and can add a unique element to the tank.

If you're determined to keep a betta and guppies together, you can try these options:

* Very large tank: A very large tank (at least 20 gallons) might provide enough space for the betta to have its own territory and for the guppies to feel less threatened.

* Lots of hiding places: Dense planting and caves can give the guppies places to escape the betta's aggression.

* Close monitoring: It's crucial to observe the fish carefully and be prepared to separate them if the betta becomes aggressive.

Remember, even with these precautions, there's always a risk of aggression between a betta and other fish. It's best to err on the side of caution and choose peaceful tank mates for your guppies.
