How to raise Elysia crispata

December 19, 2001
From: Matt Galvin

I was looking over the page on E. crispata and thought I'd send you a picture I have of mine laying eggs. The slug that I have lays eggs quite often. It seems like at least once a week. I am very interested in trying to actually raise them past the egg stage and am hoping you can give me any additional information to help? I have read everything on that is currently posted on the page, so no need to repeat what was there.

Thanx!
Matt

Dear Matt,
From Kathe's message, and Jeff Zimmerman's, it seems you need a good light source (for plant growth) and an alga the juveniles will eat. Jeff seems to have lucked on one that worked. One thing that puzzles me is that you say 'The slug that I have lays eggs quite often'. Does that mean you have only one slug? If so, I suspect its egg laying is just wishful thinking. Although they are hermaphrodites [have male and female reproductive organs], they still need to have a mate to fertilise their eggs. If it hasn't a friend then the egg ribbon will either not have eggs in it, or any eggs will be unfertilised.
Best wishes,
Bill Rudman
