I have a con in my 100gal,with my flower horn,giant gourami,and a jack dempsey.the flower horn and jack picked on him every day all day until recently, he has started to pick fights with the jack,and ignores the flower horn even when he tries to push him around while fighting with the jack.I never realized how agressive the con can be,he was always getting beat up,now he pick's fight's,Go figure........
