Great choices by firetank. They all would work great.
I have found with blue acaras that it depends on the individual fish. Some are tough and fighters some are quite docile. Like mine were.
Same goes for the firemouths. But I have also noticed that they are docile more often than tough. Cichlid Woman is completely right though the tough/rowdy ones can be a handful.
A single severum in the 65 will also work. As will a single convict. You don't want to chance getting a pair that ends up mating. The whole tank will get thrown into chaos if that happens.
