a lemon cichlid is a lelupi hope i spelled that right anyway they get around 4 to 5 inches and are very brave at that size.they like lots of rocks and a sand substrate. i had about 8 of them from years of fish keeping. if you want to breed them just pute one male with two to three females. make shure your ph is 8.0 to 8.5 and the water temp is at 80 degrees. make shure no fish are picking on them. good luck
