A unique and rarely seen characin from the Orinoco and Negro rivers in South America, the Red Line Lizard Tetra is a medium sized schooling fish that inhabits shallow, warm, acidic waters. In the aquarium, they will do best when kept with other similarly peaceful blackwater dwellers like cardinal tetras, eques pencilfish, or marbled hatchets. Like most tetras, they prefer to be kept in a small group or school of at least 5 individuals.
