New said:would 3-5 silver dollars fit in a 55?
I would only have 3 but yea they did great in my 55. I had them with 8 tiger barbs, a clown pleco and a clown loach. One of my silver dollars was by himself for the longest time (came with the tank) he quite big when I shut down the tank. He also was much less shy once I added the other 2 silver dollars.
