I have heard that arowanas have to either be housed alone or in groups of 5 or more to keep agression down. Right now I have 4 juvenile silvers in a 125 and two black in a 210 gallon tank. I have a plexiglass tank that is 8x4 being made for me now. I was wondering if that would be big enough to house all six aros. Anybody have any input?
Pls post pics when u got it!!
