woah, this is damn scary.
my condolences and hope you can start again to comm aros of similar size
i just added 2 silver aro, one 11", the other 12" with my green aro 12" (hitting 13")..
the green is the tank for 2mths, only yesterday added the 2 silvers. no fight for 2 days.. hopefully since the greenie used to be from a comm, it will continue to ignore these 2 new silver..
quite scary furthermore silvers have a more slender body which makes it look small despite the length are almost on par
