One of my roommate's bettas is a pretty blue dragon scale with bright red fins. She's had him maybe three weeks, and I noticed he was brighter in the morning right after everyone woke up versus how pale he gets in the afternoon. I didn't pay too much attention to it until this weekend (she leaves every weekend and I care for her fish). This weekend, my roomie brought her family over to see the dorm. Before they were there, he was fairly bright and active. As soon as the people poured in, he got VERY pale. His fins lost almost all their color. After they left, he perked up but didn't get as bright as he had been. And this morning, he was gorgeous. Brighter than the day she got him, brighter than I've ever seen him. But after moving around in the living room for a few minutes, I noticed he had started to pale again. He doesn't hide, he just gets very pale while he watches people. Is he shy/stressed out by people?
