I got 4 panda cories on Sunday, the lfs just got them in that day. By Monday there was only 1 left. Today I went back for an exchange and got 3 replacements and what a difference. They had a chance to adjust to the tank there and I took longer to acclimate them to my tank this time. Now I have one happy family of 4 again. I will never buy fish on the first day of their arrival at the lfs.
