Are rocks allowed when betta fish are breeding?

Yes, rocks can be used in a breeding tank for betta fish under certain circumstances. Rocks can provide a natural and attractive setting for the fish, and can also serve as a hiding place for both the male and female during the breeding process. However, it is important to ensure that the rocks are smooth and free of sharp edges, as these could injure the fish. Additionally, the rocks should be large enough that the fish cannot swallow them. Rocks can be a great addition to a breeding tank for betta fish, but it is important to use them safely and responsibly.
