Congrats, the real trick with most danio sp, is to hide eggs and fry from the adults. Java moss is great for eggs. If you can set up a second tank and get multible clumps of java moss. You switch out the java moss every few days. Similar to killi or other mop spawners. If you wish to set up an actual breeding tank meny use a marble sunstrate about an inch high. Good luck and congrats again.
