Blue Rams

I was in a fish store yesterday and saw a very crowded tank of Rams. They
were good size, at least 1.5" and their colors were fantastic however they
all had torn tails. About the last 25% of the tails were either split or
partially missing. The owner said the would grow back. Is that true? If
it weren't for the exceptional coloring I wouldn't have thought twice about
buying them.
