so we have a beautifull fh, lance ( there are many pictures on our profile). when we first got him we had him in a tank with our bichirs, well after a couple months of watching him pick on the boys we moved him to his own tank. now we are thinking about moving him to a bigger tank. my question is this. i know my fish is aggressive and can be a real mean guy, is there any suggestions on what i might introduce into the tank that could give lance some attitude right back and not become lance's afternoon snack? i attatched a picture because i never miss a chance to show him off (he is my favorite)
