    Last night (estimated day 10 post spawn) one egg coil looked like it was starting to deteriorate on the outside (the thin membrane that creates the coil tube). So I did a technique I read about called "rasping" where you suck the egg coil in and out of a pipette to release the tiny eggs to hatch. Then I took some tiny dots and put them under the microscope. Some had hatched! Fun stuff!

    Video of one hatched (early Juvenile stage) and crawling around - check out all the tiny critter activity! What are those things??

    Same close to hatching one as above, magnified to 400X:

    I seriously couldn't see anything in that specimin containter so I took a pipette and grabbed any specs I could find from the side of the container. I can't believe how tiny and FAST these guys are.

    I found this PDF paper on these guys. Very informative.

    Oddly none of them seem to care for the Aiptasia at the moment. With my jewler's loupe and a bright lamp I can see there are hundreds zooming around on the side of the container. I hope that doesn't mean they are going to starve to death.

    Do you have any pictures of your aptasia grow out setup? Or is it the same as your Berghia setup, just another kemps ice cream bucket and air stone?
