i have one 8 inch male cyanogattus (texas cichlid). He attacks the glass when i put my finger to the tank. I have him in a 75 and know that I can fit someone in there with him just not sure what type of fish would be able to handle him. As soon as i put someone in the tank I realize that the first step is to put some large plants or driftwood in the middle of the tank to break up the line of sight. And ideas?
