I've found no difference overall no matter where I have bought from,
Parasites are a norm for fish, Just like Dogs and Cats should be wormed regularly.
They can pick them up from almost anything, Within your tank, The food they eat and so on.
From my experience alot of folks have parasites in their fish and arn't aware of it.
I have even pointed the actual worms out to a few people just to have them get fummin mad in return.
