I know it’s old but I’ve read a lot that this website is a scam
Not sure about scam, but they wouldn't be the first place I ordered from. I ordered from them last year, got velvet, lost everything, and had a heck of a time getting healthy fish.
Also, the company behind the website has 2 or 3 other websites, each of them have slightly different business models.
saltwaterfish.com has a "guarantee" on their fish within 14 days I think. But it's not your money back, it's store credit back. And then it's only replaced once. So if they send you 2 sick fish(and it can happen, believe me, the cardinals I got kept dying in 2-3 days 1 by 1), they don't replace them. And you have to pay for shipping, so you either have to order more stuff to be over $100 or pay for it. So really, it's not a guarantee, it's more of a way to keep you ordering more and more fish from them. If it is DOA, then you can get a refund(still gotta pay that shipping), but in my experience most die a few days later. A cory wrasse I tried to get was DOA over and over until I gave up on getting one.
Then they have "reefs4less.com". Same exact people, but the website works a little differently. If you must order from them, I would do this one personally. They do not have a guarantee, other than DOA. It's the same fish, but for a cheaper price. If they live, you paid less. If they die, you don't get sucked into the shipping cycle, because even if you don't order more for the $100, that is still extra money for the fish due to shipping costs. You'll end up paying twice as much on saltwaterfish.com eventually anyway when you take the extra initial cost and shipping costs. So I suggest ordering from this one instead of the other if you must.
I ran across 1 other, but I forget it. I personally do not order from them anymore, but this is the low down on them.
