Sorry to hear that Tom sent you some bad Discus but I see you just joined this fabulous forum. If you had known about this site before buying Discus from Tom you would have never gone there. Please do a search for Tom here and you will find several reason to have stayed away from him. I hope you can get the discus you have back into good heath. Please post your photos and in the mean time make sure they have clean water, it's warm around 86 degrees and add a little salt to it to heal they wounds.
