Issue
No recent review of the genus, studies of types and consideration of type localities suggest that there is just the one species, Copeina guttata. Myers, 1956: 12, noted that "Steindachner’s figures are erroneously labeled and should be reversed", thus figs. 6 and 5a are correct for Copeina guttata, figs. 5 and 6a for Copella nattereri. Eschmeyer, 1998:694; Vari and Howe, 1991:36; Ortega and Vari, 1986:10.

In captivity at spawning time, after some vigorous driving and prodding of the female, male comes alongside and slightly below the female. Male then pushes an open pocket (formed using his anal fin) below the genital opening of the female; female releases eggs into the pocket and male fertilizes them and allows them to drop into a small pit in the sand that he has previously made. Male fans the eggs with his fins until hatching, in about 24 hours, and continues to guard the fry until they are free-swimming (Ref. 7020).
