This is not totally true.
First of all, most of LA's fish come from Quality Marine in Cali. QM has different sg in all of their holding tanks and there is a range. I suggest if you were to order from LA ask them what the sg is for your particular fish. I had 3 come in a week and a half ago and all three, in separate bags were 1.023. When I called LA to ask they checked a data sheet on each fish individually and told me on all of them from 1.020-1.025
Now this is nonsense saying LA has gone downhill since Petco bought them. They are doing business the same way as always and from the same supplier: Quality Marine for the most part, others come from somewhere in Fla.
DD has their fish in Wisconsin at their own facility and from what I've heard it's worth the tour to see it.
The same people that ran LA and DD before the Petco purchase are still doing things the same way.
ON a side note the royal gramma that they shipped to me was just about dead on arrival but still alive. So he got the fast track acclimation and in the tank it went. I called and told them I got a RG that was smaller than I ordered and it was about dead. She said to call back in a few days if it did pass. well it did and they told me I could have a refund on the fish or they would ship me a replacement at their expense. I'm actually going to get a larger than ordered to replace it. You can't get that from too many places on saltwater fish especially.
