Well, upon further inspection, it would appear that the tiger barbs ate the tail off the dead cory and have taken part of the tail of anouther, the third is fine. I went to the LFS and they gave me a credit on the dead one since they don't have any in, and offered to order me anouther one. After thinking about it, I decided to order the 6 barbs (3 green, 3 albino) to try and calm the barbs I have alittle. My thoughts are to take the 3 big barbs I have out and put them in anouther tank, add the new ones, then after about a week of so, I will put the big barbs back in. Basically put them on a bad behavior time out. Once I am sure the tank is stable, I will think about adding 4 more pandas.
