Oh ok but if it is so hard to determine the sex, what should i go by in order to make sure that i have some females? Is it the lighter the top fin is, it is female or that is not a good scale to go by?24Tropheus said:You really want just one male and five females for a best mix. Or at least 4 males out numbered by females.
Ideally this is true, but labs are on the calm, peaceful end of the mbuna personality spectrum. M/F ratio is less critical with labs than with a lot of other species. Unless you wind up, by pure chance, with a ratio that is extremely male heavy, I don't think you'll have too much drama. Good luck.24Tropheus said:You really want just one male and five females for a best mix. Or at least 4 males out numbered by females.
As already stated, there are no visual traits that determine a male or female L. caeruleus. Body shape, colour, amount of black and various other physical characteristics can vary between both sexes.hollyfish2000 said:One of my labs looks exactly like this photo and she's successfully held twice, so . . . A girl!
Sorry, but this is not true. I have bred several hundred L. caeruleus over the years and I have seen numerous females with black pelvic and anal fins and numerous males without.LadyMyst said:I have just bred some EY and I can tell the difference between the males and females by their bottom fins. The males are black like their top fin and the females bottom fins are not black.
