I just bought a 55 gallon tank and in another post I was given some advice on stocking. I already have 2 Acei in a smaller tank and will be buying a couple more when the big tank is ready to go. I have looked at some of the stocking recommendations, etc. I am going to stick with peaceful/mildly aggressive cichlids. I really like the looks of the Buffalo Head. Would it be compatible with Acei? If yes or no what cichlids would it be compatible with? So far the only recommendation I have found is to buy 3-4 and 2 will bond for life and the others should be returned. Any thoughts? I am just trying to decide what I want to stock and looking at possibilites. Thanks.
