Let me answer your question with another question: Why are betta fish NOT important to me? Lol. I don't know what you mean by betta adventures. Like did we take a road trip together?
1. They are important to me because they are my friends and family.
2. We grew up together in the same house. They share my pain, and I share theirs. When they are in pain, I am in pain because I can't do much for them. When I am in pain, they are in pain because I am in hospital and they don't get food or water change.
Hope this answers your questions. Have a wonderful day friend.
