It is necessary to install a filtration system in order to keep the water pure. Without fail, an external filter needs to be installed in the aquarium housing the geophagus. The subspecies of Geophagus determines both the water’s temperature and the strength of the current. These fish can survive in both warm and cold environments in the wild, but they prefer the warmer water found in aquariums. It is advised to choose dim lighting.

Spawning

Reproduction of the geophagus in captivity is not difficult. The likelihood of regular propagation increases with flock size. The subspecies of Geophagus determines how they behave during spawning.
