Not yet. I expect to get some wigglers by tomorrow, but it will be hard to tell. Unfortunately, the tube is a little too long to sit flat in the little container I have it in, so it is hard to see inside the tube. As far as I can see, there are no wigglers yet. But it's really hard to tell. By day 6 or 7, they should be free swimming. I will remove the male around that time, as they sometimes eat the babies once they are free swimming.
