About 90 percent of my fish were purchased online. The best place to look is aquabid.com. there you can check to see if your seller has ahd any problems, and see if people think they are reliable. Buying fish online is easy, and fun in a way. The sellers typically do add a heat pack to keep them. Sellers typically know what they ar doing, and wouldn't send a fish in the middle of an ice storm. I live in Florida were its always 100 degrees, but I've ordered fish from southern California and Cincinnati, Ohio in the niddle of their winter, and everything was fine with the fish.
