This could also be a question of the day, but I’m curious about the meanest or otherwise most destructive fish you’ve owned? For me it would have to be a yellow belly damsel. He made it his mission to hollow out a cave wherever it suited him, and would make a point of turning my tank into a veritable snow globe every chance he got. He would even wait for me to fill in the holes, then cruise on over and dig twice the previous hole size just to spite me.
The meanest fish I’ve seen was a trigger (Nigerian maybe?) at my LFS. It bit anyone who stuck their hand in the tank to feed or clean, drawing blood on more than one occasion. It would even attack the glass when people walked by the tank. It had to be kept separately as it also killed any fish put with it.
