I have been keeping CA cichlids now for 5 years. Recently I changed things up and cleared out one of my tanks and got a new chocolate that is about 2" right now. It is in my 72 gallon bow front for now. I am wondering how fast they grow? I have heard they are slower growing cichlids so I was wondering if this was true. I know they get about 12" long and am wondering if it will be able to stay in this tank or will I need a larger tank?
