Hey there, Im currently growing out 3 oscars for my predator pond. One of the oscars(the smallest, 3 inches compared to the largest which is 4 inches) is getting beat up pretty bad by the larger ones. He is instigating these fights but taking the brunt of it. Its gotten to the point where he just hides till i come over. I have a 40 breeder where im currently growing out a silver arowana(5 inches) and two saddled bichirs(4 inches). I could put him in there but idk if he would attack the arowana. Im not to worried about the bichirs(theyre tough) but the arowanas fins may be subject to nipping. Whats your experience when it comes to keeping arowanas and oscars together?
