I had to google search to know what a chanchito was, first image was amusing, I had to look a little deeper I think you were talking about cichlids, but you never know I always have safe search off.
For folks not in the know the Chanchito was one of the original South American cichlids brought into the hobby. Demand faded before farming of S.A. cichlids became the norm and eventually the fish disappeared from the hobby for a long stretch and has made its way back finally, they are beautiful little guys..
