it takes 48 hours for them to hatch.. if they become wigglers.. you will have a confirmed pair.. right now.. they are unconfirmed..
if your water is soft.. they have good chance of hatching..
the eggs can get fungus really fast and easy..
if they turn white.. the eggs were not fertilized..
if they hatch.. it will be hard for them to live long in a community tank..
so, putting them in their own tank.. bare bottom is best course to raise the fry.. you will also need to feed them baby brine shrimp to get their growth up.. and lots of water change.. discus fry can die pretty easy.. if you get past the 4 weeks of free swimming you are on a good track. (many people have issues at that stage)
if they don't hatch and they keep laying eggs.. you could have 2 females
and last tidbit.. crossing a pigeon blood with a non pigeon blood results in heavily peppered fry, not a desirable trait.. they are health.. just not good looking..
so crossing a PB with PB or NON PB with NON PB..
PB can pepper pretty easy.. its due to genetics and environment.. if they are in a dark environment.. they get really peppered..
hope they hatch for you to get confirmed pair
