So far all of my livebearers have given me fry, when I was trying to save fry, except my Brachyrhaphis roseni. I just got mine about a month ago and don't have a tank set up to save their fry yet. I will probably go with java moss, a few killie mops, a coarse substrate, like marbles and maybe even a tank divider to save a few fry. These fish are some of the toughest to breed when it comes to adults eating fry. So far all of my other livebearers had been producing fry just by providing the right conditions for the adults to feel secure and providing some cover in the form of java moss for the fry.
