Several species of pike cichlids from the Río Uruguay drainage in Argentina have begun to be exported in recent years. The most attractive of these, including Crenicichla minuano, C. hadrostigma, C. missioneira, and C. tendybaguassu, started to appear in 2006. Unfortunately, just five years later these lovely fishes had virtually disappeared into oblivion, despite the successful breeding of what was arguably the most interesting species, Crenicichla tendybaguassu (Big Lip Pike Cichlid), by Matthias Kählig in Hannover, Germany.
