I thought 1 arowana is too lonely in a tank.  I want to eventually keep a pair of RTGHBs.  How many small ones should I buy and grow out so that I can keep a pair at the end (and sell off the rest)?  How big should they be before they pair up?
I am setting up a 225G (30" wide) but I may go larger in the future .
.
thanks,
/David.
