Congratulations on your new goldies!
From what I understand you now have 4 goldies ( Rocky, Pob, Mini me, Baby) in the 190 liter tank...

Before you decide to keep and start raising goldies you have to think whether you can provide them the quality life they need and that means if you can provide them the required space (based on the number of goldies you will have) seeing that they grow very fast and get to be quite big...

Also, you will have to set up a cycled tank for your fry after they hatch...because they won't do very well when you will have to move them from the breeder tank to a tank of their own if that tank is not cycled..

The unfertilized eggs get a white-opaque color at about 24 h from the spawn and should be removed before they get fungus on them because they pollute the water. The fertilized eggs are usually white-clear...you can see the eyes of the fry after about 2 days and they usually hatch after about 5 days...In the first days after hatching you don't have to feed them..when they start moving and searching for food you should start feeding some boiled egg-yolk or liquid egg-yolk that can be found in pet stores..

I have some recent fry experience and if I made some wrong statements, I hope the goldie experts can correct them...I also hope that I was able to clarify some issues that were concerning you!

Waiting for some photos of your goldies!
