What kind of tank should I buy for my betta fish?

The ideal tank size for a betta fish is 5 gallons or larger. This will give your betta plenty of room to swim and explore, and will also help to keep the water quality stable.

Tank Shape

Bettas prefer tanks that are longer than they are tall, as this gives them more swimming space. Avoid tanks that are round or square, as these can make it difficult for your betta to swim properly.

Substrate

The substrate, or bottom material, of your betta's tank should be smooth and free of sharp edges. Gravel or sand are both good choices. Avoid using substrates that are too large, as these can be difficult for your betta to navigate.

Decorations

Bettas love to explore their surroundings, so it's important to provide them with plenty of decorations. Live plants are a great way to add beauty and interest to your betta's tank, and they can also help to improve the water quality. Other good decorations include driftwood, rocks, and caves.

Water Quality

Bettas are tropical fish, so they need warm water that is between 75 and 82 degrees Fahrenheit. The pH of the water should be between 6.5 and 7.5. You will also need to remove any debris or uneaten food that is in the tank on a regular basis in order to keep the water clean.

Filtration

A good filtration system is essential for keeping your betta's water clean. A sponge filter or a hang-on-back filter are both good choices.

Lighting

Bettas need a light source for about 10-12 hours per day. A simple desk lamp or a fluorescent aquarium light will work fine.

Additional Considerations

In addition to the above, you will also need to purchase a heater, a thermometer, and a water conditioner for your betta's tank. You may also want to purchase a betta hammock or leaf, which can provide your betta with a place to rest.
