Hey all, at the moment am keeping my 1 inch dempsey and 1 1/2 inch acara in a 55 gallon tank. Have been planning in the next few months to pick up a 100 gal tank off a friend. Have read that its best to let the cichlids you plan to keep together grow up together. Was wondering what some of you seasoned experts would suggest. I was thinking a gold saum but dont no how that would go? Would my aggressive acara kill him as they look alike or would he be able to handle himself? Any advice would be appreciated
