hi..i'm about to set up a new tank main fish will be only one arowana but think about to add some fish in it so here is my option,,my arowana will be around 9" so think about between 9" kamfa flower horn or a group of altum angle fish ,,its very hard to choose between these two .kamfa has a nice pearl and very big head same as color( this one can get along with other fish no mean) or about 6 of altum angle fish ( i'm not sure if i keep them in blank tank i'm not planning to put some plant in it) ,,so i want to hear what you guys think,,,thank you
