If they came in dead they wouldn't have paid.... that's normally how it works.
I too have heard of people buying fish that looked terrible and grew up strng and good, and frankly the majority of rams do look terrible in the stores. You have to look for bent fins, vitality other things, but there are a ton of really poor quality rams floating around now, and you can't repair 10 gens of inbreeding or breeding out of poorer and poorer quality stock with good water and a good diet.. Good quality is the exception rather than the rule.
