- Tank Mates: Black Lyretail Mollies are generally peaceful and can coexist with a variety of other peaceful community fish. Suitable tank mates include other mollies, guppies, platies, swordtails, tetras, and peaceful bottom-dwelling species like corydoras catfish. Avoid keeping them with aggressive or fin-nipping fish that may harass or damage their delicate fins.
