The same thing happened to me when I was considering purchasing a snook, then the price went back up and I decided I didn't want one that much. They are cheaper when LFS have them, but they are not common except for petsmart which does for some reason
They sell the snook for 29.99 in my local petsmart, so even though the information on the labels is wrong, the majority of people who buy fish at petsmart aren't going to fork over 30 bucks on a fish. Most keep smaller community tanks and would rather buy a bunch of 2 or 3 dollar fish instead.
yeah, they're $30 at my local petsmart, too. sign says they get up to 8", and they've had the same two for at least a month. if I had room for them, I'd try to make a bargain with a mgr. I'm overstocked as is, though.
