Lettuce Nudibranch – 03/07/09
Hello all (ONCE again)
<Monique>
I have been searching for the past 4
days to figure out an answer to one specific question, I hope you know that
I try using all the resources available to me first, if no avail then I try
you guys...
<Ok>
Here is the deal: I recently purchased a "lettuce
Nudibranch" (please see attached picture) at one of our LFS. Its now been
about 4 weeks and has laid a egg coil (from what I've read online that's
what it is).
<Yes>
What I've read states that the are hermaphroditic,
and as such can fertilize their own eggs (though not typical).
<But might
well have done the "genetic material swap thing" before your, the store's
acquisition... can store sperm>
As we only have one, and are not sure of
the exact species, we were wondering if just ANY two "lettuce Nudibranch"
can reproduce offspring?
<Mmm, not across species as far as I'm aware>
Or do they have to be the EXACT SAME kind, to reproduce?
<Maybe posit
this query with BillR at SeaSlugForum...
http://www.seaslugforum.net/>
There is nothing that I have found that has answered my questions, I was
even on the SEA SLUG forums looking around regarding my issue.
<Oh! A
superlative site>
See we would like to get another to see if the eggs
would hatch and have offspring,
<Mmm... a worthwhile speculation... poss.
goal... but not easily done by home hobbyists... do investigate these
animals early life histories...>
however we aren't even sure of the
"type" of lettuce Nudibranch we have.
I'm thinking its ELYSIA CRISPATA??
<Might be. Again, send the pic to SSF:
http://www.seaslugforum.net/display.cfm?id=11846>
, and of course like
always the LFS is absolutely NO help. When I went in there they told me "we
don't know because we don't sell those 'things' here". Which was of course
frustrating as I just purchased mine from that exact store about a month
ago!!!! Any help would be GREAT!
Thanks for you time! And again all the
help!

Help ID Tank Spaghetti � 11/14/08
Dear Crew,
<Hello Andy.>
It's been a long time since I rapped at you. I've been out of the loop
because my tank crashed in September and I haven't had much to write about
<Sorry to hear about that.>
-my only inhabitants are a Kole Tang, a Sea
Hare (Aplysia californica) that I borrowed from my LFS to deal with the
incredible amount of algae that plagued my tank after the crash from (I
assume) all the nutrients that were released when $3k worth of fish and
coral disintegrated, and a bunch of hermits and snails. I know this Sea Hare
is a temperate water species and will eventually starve in my tank, which is
why I borrowed it rather than purchased it--I needed something big to eat an
incredible amount of algae. Anyway, as I mentioned there is very little in
my tank--I am letting my tank settle/re-mature and don't want to load it up
with any fish for a few months. Almost nothing survived the crash, so almost
all life other than the above is new that came in on a few new pieces of LR
and some bristleworms, etc. that I transferred from my other tank. So,
imagine my surprise when I found the attached on the underside of a piece of
live rock tonight. This mass looks like a handful of spaghetti (same
thickness and about 4" in diameter). It appears to be some type of egg mass,
but the only thing that could have deposited it is the Sea Hare. Am I right
on this?
<Absolutely. These are sea hare eggs. Thanks for sharing. Do you
know the National Resource for Aplysia at the University of Miami? You'll
find information on the lifecycle, larval stages there. Rearing procedures
are also briefly described on their website http://aplysia.miami.edu.>
Thanks! Andy

Help ID Tank Spaghetti II 11/14/08
Wow, thanks Marco. Does this
mean I'm going to have 8 million Sea Hares in my tank?
<No, are they
fertilized at all? I thought you only got a single specimen.>
In the
normal tank, would most get eaten by fish, corals, etc?
<Even if you had
two and the eggs were fertilized, few would have a chance. Not all would be
eaten, the rest would be filtered, skimmed. If you want to raise sea hares
you need at least two, and contact the National Resource for Aplysia and see
their site for Aplysia production.>
Thanks again. Andy.
<Cheers,
Marco.> |

Green Slug
Hi Bob,
thanks for your info on the Fingerfish. I
got a Green Sea Slug (Elysia) last week. It is doing fine. Yesterday, it
started to lay eggs in a spiral pattern. Are those eggs?
<Yes>
Will they hatch?
<Perhaps.>
Will they live?
<What will they
eat? What is the species life cycle, developmental history? Insert the
name in your search engines and find out. Bob Fenner>
Thanks.
Lettuce Nudibranch or Elysia Crispata Eggs - 1/18/07
<Hey
Michelle, JustinN with you today.>
I just bought one of these
magnificent creatures last week and it has laid an egg strip in my
tank. How long does it take before the eggs hatch and should I turn off
my protein skimmer and cover the bottom of my filter so that the larvae
don't get sucked up? Any info at this point would help.
Thank You
Michelle Worley, Ohio
<I'm sorry, Michelle, but I can't seem to
find any solid information on the gestation period of Elysia crispata
eggs. Shutting off your protein skimmer will likely increase the chances
of survival here. Good luck! -JustinN>
