No ...gave up on the place over Xmas cause they just didnt have anything there. Is that where you got yours?

What i have read .... hey we all know how reliable this info is.... the first couple of 'rays' on the dorsal fin are serrated on the male...

Certainly the three at organism are males and the ones at tower Junction all looked like males. Certainly the three i came home with are all males. However i had been assured that at least one of them was a female. :-? Not likely from their behaviour I suspect...

I find the best way to sex Bolivian Rams is to drop a group into the tank. If they scrap and squabble, they are males sorting out their pecking order, if they are aloof, they are females waiting to see who's the most suitable bloke-fish. When they pair off, they are generally male and female, but in today's permissive society even this isn't an exact predictor, and they are south american after all.

The red extensions on the tail are also a good way to tell but males and females have red and the extensions don't grow in until they are older. Males are also supposed to have longer first two spines on their dorsal fin, but I find this ambiguous at best.
