This species, introduced into the hobby in the early 1960s, has bright red coloration when in peak condition. It is, however, somewhat more demanding with regard to water conditions than its close relative, M. melanopterus (Black Phantom Tetra). Two other Megalamphodus species are also occasionally available: M. axelrodi (Calypso Tetra) from Trinidad and M. roseus (Golden Phantom Tetra) from the Guianas.
