ive had about 3 silver aros before im on my 4th one now, one of my first ones liked to attack the frontosa i had in the tank. the aro was about 6 inches and the front was 4
I have only ever owned one type of aro and thats the silver so i am not saying which is more aggressive. But ill tell you what, mine is a beast . His fav foods are treefrogs and big lizzards.He will eat anything that will fit in his face. He has killed 2 bass (lgmth) and a 7in longnose gar was lunch. He is about 18 in long now and growin fast.
