Discus do require more planning than many common freshwater fish. They need warm, clean water, a mature aquarium, compatible tankmates, and an owner willing to follow a consistent maintenance routine. What they do not need is constant panic, endless chemical adjustments, or a laboratory disguised as a living room.

Abrupt changes in water temperature and chemistry can cause significant stress, shock, and even death. This guide outlines the standard and most effective procedures for temperature acclimating your new fish.
