I had a Vieja Syn in a 180 CA/SA that I had set up. He was the king of the tank. Very aggressive. I made the mistake of adding a Blackbelt (Vieja) way bigger than the Syn on a Friday, then went away for the weekend. When I came back the Blackbelt was beat to near death in the upper corner of the tank. The Syn was still nipping at him. I took him out and put him out of his misery.
