Here's why:
* Puddles are temporary. They dry up quickly, and betta fish need a stable water environment to survive.
* Puddles lack oxygen. The water in puddles can become stagnant and low in oxygen, which is essential for betta fish to breathe.
* Puddles are often polluted. They can contain harmful bacteria, chemicals, and other pollutants that are toxic to betta fish.
Betta fish are native to Southeast Asia and live in slow-moving, shallow waters like rice paddies, swamps, and canals. They need a consistent water temperature, good water quality, and plenty of hiding places.
