I currently have a 500 gallon setup thats 5ftx3ftx2.5ft that is home to one lone 15in old as dirt oscar. My lfs just got in a 10in dovii, which is a fish i have always wanted but didnt feel like growing one out. i would only need to keep them in the 500g for about 4 months untill i move the dovii into a bigger setup. What are the oscars chances of survival? the oscar isnt a mean one but hes not a pushover either. would his size be enough to keep him alive for the few months or do you think the dovii will go seek and destroy mode on him?
