I am curious if this would work?does anyone have such a group?pictures?I'm thinking of putting my arowanas together,that will be three blacks and one silver??I know i am .
I got 10 silvers and a green aro kept together. Currently doing very well. I did not get my lot together at the same time. I simplty just add pieces by pieces at different time over a period of 1 month plus.
If you have the tank for that the more aros you have will spread the aggression if you only have two one may target the other .You will have to deal with a large bio load so you may want to increase filtration and relocate big messy oscars.
