I just received the two red lizard whiptails, shipped Saturday. Just a bag of water in a box and two little fish. I think they spent a lot of that time traveled in air-conditioned environments. The KH of the water they were shipped in tested at 3dKH (same as what's in my tank). It's still early, but they look happy. Yea, I couldn't wait to add them to the tank, once everything looked stable.
