I just found two spotted silver dollars at petsmart. I'm not sure how rare it is for everyone else, but this is the first something came in to my petsmart labeled wrong. My petsmart is pretty good with husbandry of their fish. I dont even know how that got upside down.
I live in the Philadelphia area and the majority of Petsmarts here have them frequently. I picked up two recently, going to grab a few more next time I see them. Nice pickup!!
Well here are some better pics of the two little gents
Here is the boss of the tank They ar ein my little brother's 20 gallon for now, but I will place them in my 40 when they get bigger.
The Petsmart silver dollars are always a grab bag type of assortment from what I've seen. I've even heard of someone picking up a metynnis fasciatus (tiger striped SD) at a Petsmart.
