Trilobite Posted July 3, 2011 Report Share Posted July 3, 2011 An interesting article about sex ratio distortions in Bettas. http://bettysplendens.com/articles/page.imp?articleid=1248 Basically it suggests Bettas are able to modify the sex of spawns. If you breed an old female to a young male you will tend to end up with more males. However, if you breed a young a female to an old male you will get more female offspring. :smln: Quote Link to comment Share on other sites More sharing options...
