It will be almost impossible to raise the fry in a community tank. I have tried doing this a few times as my two pair of rams are constantly spawning and I was hoping in a heavily planted tank, it might work.
Mine spawn about once a week and generally, the eggs fungus before hatching but, I have only managed to get the fry through their first week before they disappear in my community tank so, if you want to try and raise these fry, definitely move those eggs to your 15.
