Flaring is a natural behavior for male betta fish, and it is often used as a display of dominance or to defend their territory. Therefore, it is not necessary for you to actively encourage your male betta to flare. However, if you want to observe your fish flaring, you can place a mirror near their tank, which can cause them to flare in response to their own reflection.
It's important to note that constantly flaring can be stressful for betta fish, so allowing them to flare too often or for extended periods of time should be avoided. Additionally, betta fish should have ample space in their tank to swim and explore, as well as hiding spots and adequate water quality to keep them healthy and happy.
Overall, while allowing your male betta to flare occasionally can be enjoyable to watch, it's important to provide them with a comfortable and stress-free environment to help maintain their overall health and well-being.
