This is a fish that falls in love, even a heart attack if the lover goes away


Researchers in France, have discovered cichlid convict fish (scientific name is Amatitlania nigrofasciata) is a species that is extremely aquatic, monogamous. They even suffer great pain if their partners leave.

Perhaps even more heartbreaking when the female cichlid, forced to live with the male that he does not like – leads to many "pessimistic" behaviors.

Researchers in France believe that the process of making cichlids develop monogamous relationships to better protect their offspring.

To measure the mental response of cichlids when faced with separation, researchers from the University of Burgundy, France, trained females to use their mouths to open two small boxes in the tank. Temporarily called "positive" box and "negative."

The "positive" box contains fish food, the "negative" box is empty. They have black and white covers for easy identification.

Then, they put a gray box of "gray" cap in the middle of the tank to see how the children responded.

They argue that the optimistic cichlid will try to open the gray box to find more food; and the pessimistic cichlid will hesitate, not even opening any boxes.

This study was published in the journal Proceedings of Royal Society B, showing that the cichlid will take the time to try to open the gray lid if kept with the male it loves.
