U are right Doug. LFS dont know how to take care of discuses. I ever left 5 adult discuses at a LFS for them to sell. In less than 3wks, all 5 died. Asked LFS owner how he took care of them. He never did WC, when discuses started losing appetite, he did a 90% WC. When I visited, my discuses already turned black. Of course they will die - of PH shock.
Since that experience, I never leave any discuses at LFS for sale anymore.
