Then you know that every fish is a little different they do have personality. Some are hyper aggressive some are more laid back. Festae are no different. In general they are not the glass bangers that a devil or trimac or dovii can be, but I wouldn't call them boring. Mine are highly interactive with me, He try's to splash me when I'm near the tank, he will chase his girl away every time I clean the tank as if he's trying to protect her or something.
In the end different strokes for different folks I guess. I just wouldn't apply a blanket statement of they are boring that's all.
