Here are the Berghia eggs at 6 days post-spawn. Looks like they have expanded slightly.

This evening I noticed that the egg coil was starting to become detached from the live rock that it was on. I is now 7 days post-spawn, so the outter egg membrane may be starting to break down in preparation of hatching. I removed the egg coil from the rock and placed it in an 8 oz storage container along with two aiptasia and will float it in the sump to maintain the temperature at 78 F. There is no aeration in the storage container, and based upon a paper from Jim Welch, that should produce a higher % of settled larva.

Looks like some of the eggs might have hatched. I can see very tiny slug-like things slowly moving along the bottom with a 4 X magnifing glass. They are basically white with a slightly greenish center, and some are moving dragging an aiptasia tenticle. Can't get any very clear camera shots of them with how small they are right now.

Here is the best picture I can get of two of the Bergia larva (just too small to photograph well with a regular camera). I have circled the two, one looks to be eating the tenticle of an aiptasia.

Unhappy ending. A bristleworm got into the rearing container, and even though I remover it, I was never able to find another Berghia in that container. All of the Aiptasia in my reef tank disappeared, and I was never successful in finding another Berghia (although that must have been why all the Aiptasia disappeared). I did try to borrow an Aiptasia covered LR to lure the Berghias to it, so I could recover them from the reef tank and start a separate culture, but I never got one to come to the LR (that I could see) and decided I'd better get those out of the tank before I get Aiptasia in my reef tank again. Looks like I am out of the Berghia business for now.
