Round bodied, bright orange, and one of the most interactive fish you can keep. They learn who feeds them and they will come to the front of the glass for it. A hybrid rather than a wild species, first bred in Taiwan in the 1980s, and the beak shaped mouth that comes with that cannot close all the way. It makes them far less able to do damage than most Central American cichlids, which is why they get on with more tank mates than you would expect.

Feed sinking pellets small enough for that mouth, and keep the substrate soft and sandy because they dig and will scrape their faces on sharp gravel. They produce a lot of waste for their size, so filtration and regular water changes matter more here than usual.
