When Roland Giroux noticed his blood parrot cichlid was being bullied by his other fish, he sought to make it more sociable by hand feeding it frozen blood worms.
After a few feedings he noticed that the fish enjoyed the interaction and even began to seek more pets and scratches. Now the fish gets agitated if Richard doesn't spend some time petting him like a tiny finned-puppy every day. The fish also clearly loves the attention and extra love it gets from its human.
