where can u get these and how can u tell between male and females
Sex differences: Males are larger then females. Males can grow up to 8 cm whereas the females can get to 5 cm The first rays on the male's dorsal are greatly enlarged (spiky looking). The dorsal, anal and ventral fins are elongated. Manmade colour forms seem to lose a lot of the elongation of the fins.
Females exhibit black on the leading edge of the pectoral fins. Females will turn yellow with black when guarding eggs or fry.
