Three Spot Geophagus (Satanoperca Daemon)

Three Spot Eartheater (Satanoperca daemon) The Three Spot Eartheater is a striking South American cichlid known for its shimmering blue spotting, long flowing fins, and bold black markings along the body. Native to slow-moving rivers and sandy-bottom habitats in the Amazon basin, this species spends much of its time sifting through substrate in search of small foods—giving it the “eartheater” name. Despite its intimidating scientific name, Satanoperca daemon is generally peaceful for its size and does well with other calm to moderately active South American fish. Its elegant swimming style and reflective coloration make it a standout centerpiece in large natural aquariums.
