LiveAquaria has been a bit of a challenge to deal with. We wanted one specific fish from them (a white cheek tang). We got an email from them saying it was in stock so we ordered it and figured we'd order a couple of other things while we were at it. The day the order shipped we got a shipping confirmation with a note saying that some items weren't in stock and will be backordered. Of course, one of the items was the tang! We called them to complain and got a bunch of lame platitudes. We were basically told that when our items were ready they would just ship and we'd have to be home to receive them.
We have gotten one of the corals that didn't ship originally, but still no tang. Also, we ordered 3 trimma gobies, two of which came in dead. We ordered two sexy shrimp, one of which died the second day. We ordered an alveopora and received a goniopora! We called and complained and got credit for the dead fish and shrimp, a $10 gift certificate and they will send the alveo when they get one.
They tried their best to make good on everything, but I don't think I'd deal with them again. (Sorry for being so long winded!)
