Bought an 8" silver for $40 six weeks ago. Took two weeks before he would eat anything and I tried everything. Finally he decided that it was time to eat and boy did he eat. Siversides,crickets,krill,market shrimp. You name it he would eat it. I practically hand fed him in the end and had been treating him like one of my kids. He was 11" when I measured him after picking him up off the floor stiff as a board. Jumped out of that inch and a half opening where the plastic attachment fits on glass versatops. He was well on his way to being a large and impressive arro when his life was cut short. Just a warning: keep your tanks totally covered. Too much time and money is invested in these guys to let them just jump out of your tank. He WAS my favorite fish and a hard lesson was learned.
