I purchased 4 Hoplarchus psittacus (True Parrots) from Ewok a couple of months ago. He previously had them separated due to aggression issues towards eachother, I have done the same thing to prevent injury or death. I am currently trying to downsize my collection of tanks and would like to consolidate these fish into a community tank with eachother..... IS THIS POSSIBLE? Do you think they can live together in a 240g (8 foot tank)? They're currently 6"-9". ULTIMATELY I would like them to pair off..... I'm thinking that's just a matter of luck. Thanks.
