Is my bad luck returning?

Grrr. I got a panda cory baby from that store in Philly,who replaced my dead Albino Cory. I just found that panda dead. And I know it was that one,bc it had a nip its dorsal fin. Seems to me now that if it has a nip its gonna die. The last one I got from my lfs had a nip in its dorsal,and that one died less than 24 hours later. This one lasted um 5 days. The new albino seems fine for now. ugh. Do you think I should take it back? Its within 7 days (ill have to go down sunday again). Honestly though all the pandas in that tank didnt look very good. I shouldnt have gotten it.
