Too bad about the eggs but give them some time it may take them a few trys to get it right. I'm growing out a group of 6 also. Mine are about 2-2.5" and chase each other all the time, nothing serious though but they aren't spawing either. I keep mine with Angles, Festavum, Metae, Krobia XO and a GT with no problems at all. Good Luck with them beautiful fish.
