    How many days will Elysia spawn after mating?

      That’s a really good question. I have never tracked it myself, but I assume it must be soon after, because the eggs develop rapidly once they are laid. However, they may be able to store sperm. Will check the literature and find what I can.

        Thank you very much. I have a small aquarium for Halimeda and Elysia. On Saturday night (16/07/2016 in Thailand), they had mating. Now (Monday morning), I have not seen any eggs of them. Thank you again for your help.

          That’s exciting. Please let me know if they lay eggs, and which species you have. I hope to have time to check the literature later today.

    They already laid eggs, but I do not know what time is. I saw in this morning (about 9 am). I have done the experiment on Elysia pusilla.

      That is great news. There is a lot of data regarding time to hatching after oviposition, but I can’t find much about the time between mating and egg laying. Thanks so much for the posts!
