Can I take back the "peaceful" personality part? Argh...I am wondering if he is in fact a green terror x blue acara cross. He absolutely ripped my severum a new one last night. I turned on the light to find the severum in the corner and the acara just hitting him over and over. I fed them and they have settled down, but my severum is missing chunks from his fins, bite marks all over him, sigh. The severum is pushing 7 inches, the acara is maybe 3". I guess I'm going to go trade him in...damn, he's so pretty, I wish it had worked.
