All cichlidophiles know how amazing the cichlidae family of fish is just from the incredible diversity of behavioral displays – from aggression to breeding to brood care. There are even studies that suggest quite a range of cognitive abilities, including the one I posted on nearly a year ago that concluded cichlids have the capacity for long term memory.  Adding to the cognitive function discoveries of cichlids is another recent study that found male Pelvicachromis taeniatus demonstrate olfactory self recognition. Basically the study found that, given two caves to choose from, one pre-scented with their own chemical odor and one pre-scented with the odor of another male, P. taeniatus gravitated toward their “own” cave versus the cave of a non-family member or even a sibling.
