Rio Grande Cichlid. First, in 2003–2004, we trapped H. cyanoguttatus in Lake Pontchartrain (an oligohaline estuary) to determine if this freshwater species occurred in estuarine habitats. The effects and potential for further spread of H. cyanoguttatus is uncertain. The Rio Grande Cichlid is the only cichlid species native to the United States. Females close to spawning had the highest mirror scores, whereas male scores were highest early in the reproductive cycle. Ichthyol Res 51:354–359, Maynard Smith J (1974) Theory of games and the evolution of animal contests.

The Rio Grande cichlid (Herichthys cyanoguttatus) has been established in the Greater New Orleans Metropolitan area for at least 20 years, and its effect on native fishes is unknown. | Google image. The effects and potential for further spread of . and Mexican boundary survey, and in Texas, by Captain Stewart Vliet. Spatial predictability was manipulated by varying how often these probabilities were randomly assigned to the patches over a 3-day experimental period: once (Predictable), six times (Intermediate), or 36 times (Unpredictable). Despite being known for its violent temper it attracts a lot of admirers, mainly because of its bright colors.
