I just want to comment that when people say DD QTs their fish, that they in fact do not. I would call it "conditioning" (and I believe LA calls it that too). They hold fish for a certain period of time and get them comfortable and feeding well.
...........and that's what counts. I have some prejudices; but I have never seen any company, in any business, that consistently gets the number of positive comments as do the F&S companies. ( F&S, DD, LA)BZA just isn't on LA's/DD's level.
I've ordered plenty of fish from both, and the success rate for BZA is much lower than LA/DD. I don't know anything about their processes - all i see is the end result.
