IDK if anybody on here uses AqAdvisor, but when I enter my tank dimensions and put my Oscar, GT and Con x Jack (Had to enter it as a JD) it says they'll eventually require 138% of my tank space as territory.. Am I doomed to fail? Would adding something like a Severum or some Silver Dollars help spread aggression? Really want to get this right first time, and my Oscar isn't happy in my hospital tank..
