Hi and nice to be with you all, I have just set up quite a large tank 1metrex42x33and are going to be introducing some angels .will it be compatable for them if I introduce a couple of silver dollars or are they aggresive .or if you have any other ideas for any type of mild mannered cichlids that would live alongside the angelsand a few guppies .how about dwarf cichlids. My email is fulovideas@yahoo.co.uk. I have kept community tanks off and on over the last 40 yrs .But now I think basically its got to be cichlids,thanks for the help .
