Ted, I kept a colony of A.Trifaciatta in a well planted tank with several young to mid sized discus for several months. The apisto's would pair and spawn regularly I would see the males do a threat display directed towards the discus and a couple of the females would attack them However I do believe that the discus found the apisto's amusing. Generally they interacted very little. About the only time there was much in the way of interaction was feeding time. At this time the discus (pigs with fins) would actually pay attention to the apistogramma's and try to keep them and everyone else from the food. My Opinion The Nijsenni's will threaten and possibly attack the discus when they are defending a breeding site or brood. However the discus won't much care and won't be harmed. The Dwarf pike would be of more concern. With this current tank mix you may get some spawning behavior from the apisto's but the pike will be well fed. Just my opinion.
