Dear Bill and Forum readers,
I wanted to provide a brief update to my tentatively ID'd Spurilla neapolitana [see message #14532]. They have laid a total of 5 egg masses but I believe the first one was out of water for some time since I didn't notice it and it has not hatched. Egg masses 2-4 have hatched but I do not see any babies yet. Egg mass 5 was laid last night in the new blue bucket that provided a better photo opportunity.

Attached are pictures of egg mass number 5. Adults appear healthy and mate every two to three days. It seems they need one anemone every 3-4 days to be interested in egg laying. The second egg mass is slightly overexposed to bring out a little more detail. The eggs appear quite small so I'm beginning to think the breeding efforts will not produce young.

I am putting plastic plates into the adult's bucket in hopes they will lay some eggs on there and I can remove one mass for better photos.

Dear Brian,
Thanks for keeping us informed of progress. I can see the eggs. Don't give up hope. There is always a chance they will develop into lecithotrophic larvae. This is a type of larvae which has a short free swimming veliger stage, but it does not feed in the plankton. Some coral eating aeolids have this form of development, in some case spending less than an hour swimming. These are easily bred in the aquarium.
Best wishes,
Bill Rudman
