As most of you experts thought that this green terror will eventually eat some or if not all of the cardinals by now. Well.......... yes, it mostly true. It has eaten a couple. I know for a fact that this is happening when the lights are off. As all of us cardinal tetras owners are aware, their colors fade and hide within the brushes. Because of this, they seemed slower than normal, almost as they're in sleep mode. It's a defense mechanism designed in the wild with wide range which is not true in my tank, since it is confined. Make sense right? With this being said. My GT is an opportunist cardinal gobbler. End result is that I now have to place them in my 10 gallon for the time being. So, what does this mean. I'm going "shrimp" and look for another small tank, maybe some lace rock, branchy wood, and then house these cardinals. YAY another project! Overall, I am pleased as the GT and GG show no interest to bully or mess with my plants.
