The Three Spot or Demon Eartheater (Geophagus sp.) is an impressive and peaceful cichlid that originates from the blackwater tributaries of the Rio Orinoco and Rio Negro in Colombia and Brazil. It is known for its remarkable appearance and is considered one of the most visually striking fish in its family.
As an eartheater, this species has adapted to feed by ingesting mouthfuls of fine sand substrate and sifting out small food items such as insect larvae and crustaceans. In the aquarium, they thrive when kept in groups, and they generally coexist well with other peaceful cichlids and fish species. Despite their size, they are typically safe with smaller fish.
In their natural habitat, Three Spot Eartheaters are exclusively found in acidic waters. To replicate their preferred conditions in captivity, it is recommended to keep them in soft, warm water with a pH level of 6.5 or below. Maintaining temperatures around 80°F (27°C) is also beneficial. These cichlids appreciate the addition of tannins to their water, which can be achieved by using botanicals like Indian Almond Leaves or similar materials.
Overall, the Three Spot or Demon Eartheater is a captivating and peaceful cichlid species that thrives in groups and requires specific water conditions to ensure their well-being. With their stunning appearance and unique feeding behavior, they can be a fascinating addition to an aquarium with suitable parameters.
