Since I recently upgraded, I have a new home for my wifes angel fish, my old 55 gallon. She saw some discus at the lfs when I was buying my 100 gallon and she said she wanted them. I wouldnt mind trying my hand at keeping them, but my water is all wrong, GH 150 ppm, KH 300ppm, pH 7.2. Does anyone have any other suggestions for tankmates that would do well with angels?
