been thinking about getting a black aro to complement my 5in silver i currently own. however, i know that 2 silvers will not get along and that a jardini (for the most part) has to be the only aro in the tank after 8in or so.
its not really the kind of arowana together that can be the problem...
its the number of them together... 2 arowana rarely works as they focus all their aggression to each one, trying doing 2 silver and 1 black.
Blacdks together are more bickering than silvers. Silvers, on the other hand, have more powre of agression.. 2 together do not cope well.. all numbers above 3 have worked for me...
But I second David's opinion hereabove..blacks get more on the nerves of each other...
