I didn't have such experience with LA so far, but in generally I realized especially with Fish, Cheap means High RISK.
Unless we have our own QT which offsets this Cheap prices, we are playing the game.
Marco's QT and reefescape QT are the only sources I trust and put the fish directly into my DT.
The risk is highly multiplied when we are adding one fish bought from these cheaper sources to existing healthy fish in our system.
I have personally experienced for myself that the cheaper prices and the cost of QT, fish die in QT and cost/time of existing fish killed is NOT AT ALL WORTHY!
