Hey Guys, new to the site and wanted to run this by you. I have a 180 gallon tank 6ft. with 1 Oscar, 1 Severum, 1 Chocolate (coryphaenoides), 1 Blue Acara (so I thought), and 5 Silver Dollars. My Oscar is the biggest of the tank at around 7inches. My question is, I think my Blue Acara is a Green Terror (bought him young) and after some growth he looks like a GT, he is only about 3.5inches or so. There has been no aggresion since the tank has been set about (about 6 months), Im just worried that the GT will not fit into this stock list. My Oscar is my priority in the tank and if you guys think the GT will be a problem in the future I will take him out. The GT is one of my favorite fish in the tank and would like to keep him in there. Do you guys think this will be a problem? Thanks
