Java Moss and Betta Fry?

So I am getting into breeding betta fish. My first spawn, I fed egg yolks, followed by fry powder, and then super crushed flakes. I wound up with one surviver, my dear little 13 week old baby who is happy and healthy. I think a bacterial infection of the gills took out the rest, even with precautions and treatment (no chemicals). I have a quality breeding pair coming from a breeder now, so I can try breedig higher quality animals. I have different ideas, and read how java moss is excellent for reducing nitrites and can help cultivate infrusoia. I also have microworms on order for when the future fry are big enough to eat it. So my question is if anyone has any experience with java moss and breeding betta fry? Has it helped or hindered anyone?
