Known by several nicknames including Bolivian Butterfly and Ruby Crown Cichlid, the Bolivian Ram is endemic to the Amazon river basin. These fish can be found in several river systems throughout Bolivia and Brazil where they tend to inhabit soft, acidic waters. Bolivian Rams tend to exhibit vibrant yellow coloration on the front half of their bodies which fades to light gray at the rear. Many specimens exhibit a vertical black band through the eye as well as several transverse stripes running along the body. The dorsal and caudal fins are typically partially black in color and edged in red while the anal and pelvic fins are primarily red, accented with bright blue dots.
