I've had two experiences with LiveAquaria (LA), each of them bad. However, let me explain first. Both times I ordered, I ordered during wintertime. I don't remember if they sent heat packs, but I'm pretty sure they didn't. But during the summertime, you might be able to request cooler packs, which can keep the fish from boiling to death. Both times, I was able to get a refund on my order. The fish I ordered were a sixline wrasse, and a bicolor blenny. Finally, the main reason why I don't blame LA, was because I was a freaking newbie back then. I had hubris, and thought that I knew absolutely everything, and I'm almost positive that it was my fault and not LA's during acclimation. The tank I was working with at the time, had only been set up for a few weeks, rather than the few months recommeneded sometimes. But the customer service is wonderful, I'm currently coresponding with the Diver's Den to get more accurate information about the percentage's and types of food they feed certain fish! I'm definitely gonna order from them again.
