I will have a 240 gallon tank coming my way in the near future and would really love to have a few Bichirs. I was thinking maybe 2 Ornates but I don't know what I can keep with them 
I was thinking of maybe a Jardini, some Payara, African Pike, some kind of gar, pleco, or...idk!
I need help. Would those be safe in there? Would they attack my bichirs or would my bichirs attack them? How many of each can I put in the tank (I don't want to over-do it). And do you have any other suggestions as to what would be nice in the tank? I reeally don't know...I just know I love the look of bichirs and want some good looking and aggressive fish with them...just not aggressive towards them
EDIT: I already ahve one Oscar as well. Should I give him to a new home or would he be fine too?
