Order : Perciformes Family : Cichlidae. Other species occuring in the Xingu are too numerous to mention but the following are some examples of those that have been collected in the same habitats as G. Additional furnishings are as much a case of personal taste as anything else but the most favoured set-ups tend to feature relatively dim lighting plus some chunks of driftwood and scattered roots or branches. Rather than a single large meal offer smaller portions daily to allow natural browsing behaviour as this seems to result in the best growth rate and condition. A group of individuals should be the minimum purchase since in smaller groups weaker individuals can become the target of excessive antagonism.

A distinctive and colorful cichlid, the Blue Streak Eartheater or Geophagus argyrostictus is known only from the Rio Xingu and its tributaries in Brazil. In the wild, it inhabits very warm, clear waters in areas with powerful current, usually in relatively shallow water above sandy substrate. Like most fish from the fast-moving Xingu it is a powerful swimmer and will do best when provided plenty of current in the aquarium.
Named for the distinctive blue facial markings, this species is more aggressive and territorial than some eartheaters but will generally do well with similar sized tankmates as long as plenty of open swimming space and cover is provided.
Like all eartheaters, a substrate of fine sand is essential for their well-being in the aquarium and they will spend most of their time sifting it through their specialized gills to pick out small food particles.
