I read about these guys and I instantly fell in love with them as many of us do. I have one that is about 6 inches in a 125 gallon grow out tank with a grammodes, buttikoferi, umbee, flowerhorn and a few dithers all males (well hopefully in the umbee's case) but anyways, when I read about them, I found multiple people saying that they aren't that bad until one day they just go crazy and get super aggressive. I just wanted to know if it is possible that mine is already crazy or if he is gonna get a lot worse, like I needed to clean my other tank so I wanted to put my green terror pair in the dovii tank, I put one in and came back less then 5 minutes later and found the dovii grabbing the green terror by the back and shaking him, I instantly took the green terror out and looked at him, his back fins were almost cut off and he couldn't swim right side up for a while (don't worry he is doing better now) but is it possible that my dovii already snapped? Or is this what they're like before then? Either way he's definitely gonna need his own tank eventually
