the larger one stil shows the pigment in dorsal fin, but green. now since this morning the larger one i am pretty sure is male, green hues coming through nicely. the smaller one i am not sure as it has spangeling in fins and body, not as much as male but my worrys are that it might be a sub dominant male. and they are in a 120g so im keeping an eye on them.( large sa/ca are rare in south africa)
