Over the holiday season, I've been living with my dad and brought my two bettas with me. One of them has been kept in the kitchen during the stay. I figured my dad would tolerate/ignore him, but he has got to liking him quite a bit. He has even affectionately nicknamed him "Bubba" HAHAHA! My dad had to take care of him for a few days while I was gone and got attached to both of them, and has even said that he will miss them when they go. If he misses them too much, I'll just have to teach him how to set up a tank for himself
