Further confusion has been caused by undescribed Geophagus species from various parts of the Amazon basin being traded as geographic forms of G. altifrons or G. sp. aff. altifrons despite possessing prominent midlateral markings or vertical body stripes, whereas in G. altifrons sensu stricto these features are greatly reduced and absent, respectively.
'Geophagus' iporangensis is a beautiful eartheater from Brazil and a rather new fish to the hobby. Originally, this fish was described as a subspecies of 'Geophagus' brasiliensis. The two fish are extremely similar and one could see why they were originally described as a subspecies.
G. taeniopareius is markedly more aggressive than most other Geophagus spp. but multiple specimens can still be maintained together in larger aquaria. A group of 5-8 individuals should be the minimum purchase since in smaller groups weaker individuals can become the target of excessive antagonism.
