How many silverdollars in a 55 gallon??

[Cichla dude]

I've been really thinking of turning my 55 gallon into a silverdollar tank. My dad wants to make each of our tanks '' Amazon style'' and since Silverdollars are from the Amazon I decided to stick with em. If I do this,I will rehome the oscar and tsn. I will keep my 2 2-3'' silverdollars of coruse. How many silverdollars do you guys think I can have in a 55?? I am aiming for 6-7.. with atleast 1 being a redhook. The tank is overfiltered so filteration shouldn't be an issue. What tankmates can I coexist with silverdollars?? I may shrink the sd down to 4-5 and get tankmates haven't decided yet..

You could easily put half a dozen in there. SD's love to be in large groups to feel secure. I have 6 in a 50 breeder with a large L-114 pleco and 3 mascara barbs with out any issues. My dollars are 6 inches on average.
