I have a 100 gallon tank right now (60x18x20) that is sitting with one little Freddy in it about 3 inches long. He has been in the tank by himself for a month now and is growing pretty good as you can imagine in a tank by himself. What i'm wondering is suggestions to add to him/her in the tank. I was thinking of adding something and hoping that if I redo the rocks in the tank, it will give them a chance with the Freddy. I was hoping to get something about the same size or a little bigger, because this little guy has already chased down 2 silver dollars and took one of their eyes out, so I moved them to the 110 I have also.
