For this reason, mineral water is a popular option of water for freshwater fish. Moreover, pure mineral water comes from such sources with no pollution. There will be added no chemicals in mineral water too.

In addition, you can check the label of mineral water. The mineral contents, pH level, chemicals, source, and other necessary information are mentioned on the labels of the bottles. If you find the water parameters are safe for your betta fish, you can trust mineral water.

But, the drawback of mineral water is its hardness. The experts suggest mineral water for those aquatic living who prefer hard water.

Although sparkling water is another type of bottled water, this water isn’t good for your betta fish. The pH range of sparkling water is around 3-4.
