Just put my oscars into my divided 4ft, know they don't like each other but I'm hoping they become accustomed to each other, gonna leave them for a while, bad idea or nothing bad about it? Took this photo of them today trying to kill each other
Let them be that way, for a week or so , till they get accustomed seeing each other.
Then under supervision you can leave them together for few hrs and then decide if divider stays or goes
2 nice looking O's. IMO it's a 4' tank it won't work long term, eventually they will be 12"-14" and 2 of them in a 75gl tank is not a recipe for success.
They have stopped attacking through the divider, pretty much ignore each other, thinking of taking the divider out in the next few days and watching them for a hour or so to see what they do
