if u think bout it ... fish from LFS or farms are also from the sea .
and i think they are prone to have more disease than the ones we catch locally .
personally i have caught many fish locally ranges from butterflys ,gobys , cardinals , puffers and file fish ... they have better survival rates than fish bought from LFS ... but one thing is those caught are mostly not reef safe .... good for fish only setup .have given away many lots of them.
