we were lucky that our spawns on the go survived us being away for two weeks. thanks to my mom and sister for coming in on a daily basis to feed the kids and all the rest of our bettas as well. we didn't lose a single one thanks to them.
just took a couple of "arty" pics of two boys that will definately be halfmoon (if not already). i witnessed the one with longer fins flare and it was full 180. these pics don't show them in absolute full flare but you get the idea.

Which spawn is it?
