My little 5-6 inchers laid eggs twice and male went to fertilize but no luck. I hope to find out if one sex is fertile and one isn't, the eggs look healthy at first but then turn white and rot away over the next few days. I am going to try to cross breed but I don't know with what. 14in is crazy, I saw a pair of big ones at buzz n bees but female was smaller than male and was getting beaten up. I think from what I have observed is that the males have more pointed dorsal and anal fins while the females' are more rounded.
