Imho, dun blame any LFS..LFS are not the one who catch the fishes..even good shipment dun guarantee healthy fishes..it boil down to ur fish choosing skill n luck liao..of coz as reefers, we got to do our part as in maintaining a clean water system n read up on their compatibility..most reefers will introduce more hardy fishes like clownfish, chromis, etc to test water 1st..but do note that sometime hardy fish dun survive but the sensitive fish ok..so u will think its what went wrong..no explanation for this yea..
Good luck n happy reefing
