I tend to shop around when I'm looking for a new tank inhabitant and I always end up back at LiveAquaria. The selection is usually pretty good and I can't seem to beat their 14 day guarentee. I much prefer to order from them and take my chances with what they send me knowing that if the specimen they send doesn't survive for 14d my money will be refunded. That's WAY more than I can say for the
LFS around here. When I shop another site and the price is close I look back to the stay alive guarentee and the other sites are usually only 5 days. Not worth the price difference,
IMO, especially on any expensive fish.
The only thing that I find (and it was suggested to me during my first order with them) is to specify that you want to pick your order up at the sorting facility. My deliveries are always after 2 here and I'm usually home with fish in hand by 10:00am if I go there myself to get it. I'd rather do that they have them sit in a truck in unpredictable conditions.
Their customer service has also been very good. They've been very accomodating and have taken care of me well when I've had a problem with something that came in.
I've also ordered from Captive Reefs. Darin has been very helpful (though I know that's not livestock). My rock came from LiveRocks.com and I was thrilled with that too.
