Long story short I ended up with a jack dempsy cichlid, someone had him in a 10 gal tank and asked me if I wanted him. I felt bad and took him in. he is about 4in long, Im fairly certin its a male judging by the spots on his gills. This is my first experience with this speicies and *** quickly come to like the little guy, he comes to the front of the tank every time I walk by. My biggest concern is my tank size. He is currently living by himself in my largest tank that is 46gal. I dont have space or money for a larger tank, I was looking for others opinions if he would be ok in there long term if he is by himself (I know its not exactly ideal). Just wanted others input...oh yeah the tank is only 3 feet long but it dose have a bowe front that gives quite a bit of depth to the tank.
