ok in my oppinon as i had<until a couple of days ago> two oscars and a jag with silver sharks and tinfoils in a 150us!!!!
It works for about 1year then suddenly around six months jag went crazy, so i removed him and rearranged the tank totally and left him out for 6hours then reinterduced him and all went swimmingly for about another 4months!!!!
suddenly 2weeks ago brutis started going for my oscars litterally sheep hearding them in a corner and if they ever moved he went for them both,so after a few days i removed him to a temp tank!!!! Then after about 1odays i readded him only to find he went straight for the oscars and did same thing then started going for the foils and sharks...
so iam going to have to say no sorry,,, but iam advising you from my bad
