Do Frontosa and discus go together?
Absolutely not. All the fish you listed are from the Rift Lakes of Africa where the pH is around 8.0. Discus, on the other hand, are from the Amazon and its territories which have a pH just around 6.0. Trying to find a median will benefit neither, and keeping parameters for just one will mean the other will suffer dramatically. On top of that, your fish are far too territorial and aggressive to keep with Discus– they (the Discus) would likely not last more than a week before getting torn apart). If you want to put other fish with Discus, use smaller fish like a school of Tetras, Rasboras, or Hatchetfish, and smaller bottom dwellers (Cories, Kuhli Loaches, dwarf Cichlids, etc.). Severums and Jack Dempseys are also FAR too aggressive for Discus and will make quick work of them. If you want Discus, center the tank around Discus; do NOT try to work them in as an afterthought.
