Yeah, the sunfish is really interesting to watch. I previously said that the sunfish was around three inches but he is really around the same size as the green texas cichlids (two and a half inches), if not a bit smaller. He sure does stand his ground when they get near him though. I actually found the sunfish at petco while I was picking up some stuff. I just happened to glance into the feeder tank and saw about six of these guys hanging out with the minnows. I asked about them and the employee thought that they were tilapia, so I picked up all six of them for 15 cents each. A few died from disease and a few more jumped out the back of my twenty gallon tank, so this is the only one left. I was wondering though, have any of you ever kept sunfish with cichlids for any amount of time?
