I hope your Dad lets you keep your betta in your bedroom. Sounds like it would be a good place for you to keep an eye on her.
I think bettas really do benefit from interacting with their caregivers. It's true they are solitary fish, but in the wild I think they would have more stimulation than they do in a fish tank. The wind, insects flying above and landing on the water, the changing sun as it passes overhead, fish and other creatures that may come into their territory from time to time -- all these things and more must keep them alert and interacting with their environment. Compared to their natural habitat, a fish tank is rather static. My betta seems interested and curious when I interact with him. I do this by gently dripping water on his body with a plastic spoon, taking a small cup and scooping up water and pouring it into the tank again to aerate the water. And, of course, he loves feeding time!
