These little fish (Hemigrammus erythrozonus) have no easilly visible sexual differences util they are adult and ready to breed. At this time the females develop heavier,chubbier outlines than the males. This is due to the female filling with ova. (eggs). They are not easy to breed and are even harder to rear once they have been spawned.
The gender of a tetra fish can be determined by looking at physical characteristics such as body shape, fin size, and coloration. Males typically have slimmer bodies, larger fins, and brighter colors compared to females.
