This will reduce stress on the parents and improve the fry’s chance of survival. However, after the fry begin to accept infusoria and live brine shrimp the parents should be removed. After spawning, the parents should not be removed from the fry because the fry will feed on the mucus of their parents. Before spawning, the pair will clean a flat surface (a breeding cone is a good pick).Warm, soft and slightly acidic water is needed for spawning, constant water changes (with similar temperature freshwater) can simulate rainfall and speed up the spawning process. This is essential as it is allows the control of variables and is much easier to keep the aquarium clean. The pair will need to be moved to a separate, bare-bottom, rearing tank before spawning.Alternatively, keeping a group of at least 6 juvenile Blue Discus will allow for pairing to naturally form. Discus need their own tanks to reproduce and require constant demanding care to ensure smooth delivery of the fry.
