Researchers have long thought fish were heartless and cold, incapable of the relationships mammals cultivate, but new research among fish in coral reefs suggests fish can work in long-term paired relationships.

But in reality, marine researchers have long thought fish were a bit cold and self-centered. A recent study published Friday indicates that their temperament is warming by a few degrees.
Clownfish like Marlin and Nemo do have a symbiotic relationship with anemones, according to PBS, but another inhabitant of the coral reef – the rabbitfish – shows the first-observed signs of what researchers call reciprocal cooperation. This means one fish helps another, and the effort, no matter how small, is somehow returned.
