I have been having a problem with losing all of one sex of a fish. I am left with 2 female and 1 male red swordtail, 2 female pineapple swordtails; 2 male guppies and 2 female black lyretail mollies. I have heard that guppies and mollies will interbreed - is that true? Will the different swordtails breed with each other? Every time I add fish to my tank I lose some, so can I just keep the ones I have now, or do I need to get the correct mates?
