I have a 120g (60x18x26) and my original plan was 1 midas, 5 silver dollars and 1 pleco. This was a nice combo since my midas was a pretty mellow male that also was not a big bruiser, in fact a bit of a runt at 10" for being 2 years old! As time progressed I decided on a larger group of fish, so my 120g is serving as a growout until my 210g is set up. But it all depends on the temperament of the individual fish.
