Quality Marine, a West Coast wholesaler, has been the replenishment source for live aquaria orders for as long as I can recall. They also supply fish to some other online order centers and many local fish stores. The supply chain for marine fish is generally worse today than in the past - partly because growing demand means less qualified collectors and collection practices and partly because it is rife with disease problems. I’ve been ordering from LA for over a decade, and while disease is more rampant today than in the past, with a competent QT system, I don’t find the mortality rate to be materially worse overall (I get between 70 and 75 percent of new fish through QT). I know it has become fashionable to ‘bash’ LA because it is part of Petco (which MUST be a bad thing, right) but for me personally the data doesn’t support the rhetoric.
