Fuge hitchhiker ID, Green Slug….. 1/28/07 Greetings
Bob & Crew!! <Hello.> The other evening, I wandered through
my fish (laundry) room and stopped to look at the pods crawling
around my 40-gal sump from my 125 reef in the next room. I swear I
saw a leaf from one of the algae move....and I realized that it was
alive!!! It looks like a land slug, but all green. Only about an
inch long. No idea how long it has been in there or when it came
in. It seems happy to crawl around the ample macro algae in the tank
and just graze. I've done a few searches and can't seem to find
anything like it. Any ideas what it is??? Pic attached.
<Well, from the photo it does appear to be a Nudibranchia. I will
say first off that by photo alone…even with the actual specimen in
front of you, it is quite difficult to i.d. by exact species. They
are mostly very, very difficult to care for and have notoriously
short life-spans in captive environments. However, occasionally,
some survive….as appears to be the case with yours. It likely has a
food source, and judging from the color of the animal, (as you
eluded to) it appears to negotiate a large sum of vegetable matter,
algae, into it’s diet. I would just observe and enjoy.> <<Mmm...
likely another Opisthobranch group... RMF>> Thanks <Anytime.>

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> Sea hare sel., comp.
12/30/06 OK, so after moving my tank (150g Berlin, 250lbs live
rock, light bio-load) I had a huge outbreak of long green hair algae.
Covered everything. Tried cutting back on the light, but I only achieved
making it's color less attractive. After reading all I could, I decided
I didn't want to go with scraping, chemical, etc....but add a natural
solution. When weighing out the pro's & con's of such grazers, I settled
on a sea hare, <Mmm, what species?> as it seemed to be the most
voracious grazer. I wasn't so worried about it dying, as my tank is
quite healthy and there is much for it to eat....... but with such a
nocturnal creature, how on earth would you know if something that you
rarely (if ever, lately...) see? <Mmm, the results of their
night-time foraging?> Also, in a 150g, how much pollution/death
could I be facing if I do not find the body? <Could be appreciable
depending on the species, size... your filtration, maintenance...>
250lbs of rock is a pretty sizable pile to dig through. Thanks in
advance, my briny friends! -Pat <Do take care to try a
tropical species (not a cool/coldwater one), that is, and stays
small-ish. You have read here?:

above? There are other "biological means" to consider... Bob Fenner>
Reef safe Nudibranchs 12/18/06 Hello: Another
question for the experts as I seem to get conflicting results from my
many www searches and the LFS staff. Are there any nano-reef safe
small-size sea slugs ? <Mmm, yes... many Opisthobranchs that could
be utilized... depending on your other livestock...> I have a 3
month old 24G Nanocube which is doing well and don't want to repeat
earlier mistakes. The information on Nudibranchs seems to vary and this
in itself tells me to proceed with caution. <Mmm, yes... by and
large I would not use Nudibranchs... look to, read re other Opistos...>
I have seen "lettuce" sea slugs in my LFS's, as well as other more
colourful species with a "Ricordea-like" texture on top. Thanks for the
help, have been somewhat concerned about the number of species in the
marine aquarium trade that really shouldn't be sold to
hobbyists.....thanks again. Karl <Mmm, please see here:
http://www.wetwebmedia.com/seaslugsopisthobranchs.htm and use
the names presented as a starting point in searching further re this
question. Bob Fenner> Sea Hare Splitting? 10/23/06 Hi WWM
crew, <Hello Ryan> I have a 35 gallon saltwater tank. There is a
Coral Beauty, orange star fish, three crabs, and a Sea Hare. I woke up
this morning and I saw my Sea Hare's skin splitting down the middle.
There was something that looked like a white larva where the skin split.
I took out the Sea Hare and moved it to a quarantine tank, because I
heard they can kill your other fish when they die. <Indeed.> It
hasn't moved around in the quarantine tank so I think it's dead. Do you
have any idea of why it did this, or how I can prevent it in the future?
<Most Sea Hares, if not all, are very difficult to keep. Should only be
attempted by expert aquarists. They do not appreciate bright light and
are algae grazers. I'm quite sure none of these conditions exist in
your tank. Try something a little more easier to keep in the future.>
Thanks for your reply! <You're welcome. James (Salty Dog)> Ryan

05/10/2006 Hi, < Hello! > Can you purchase a Clione
for a pet ???? < I have never seen them on any list of availability. >
Is it legal to have them in the United States . < I am not sure about
that one. > I would love to have one, they are so relaxing to watch
them swim around < They may be obtainable through scientific supply
houses. I strongly urge you to learn about their feeding habits, and
learn how to raise their food first! There is more information to be had

Sea hare growth ... no info. 5/4/06 My sea hare has
a what I can only describe as a growth on the side of her head, it
started off as a little growth but by the evening it has grown really
long, part of it is long and thin and the end piece is bulbous and a
pale blue green colour she is still alive, any ideas???
Thanks for your help Ellire <Perhaps a tumor
of some sort... I'd be checking your water quality, moving the animal if
you have another "clean" system... doing water changes, employing
chemical filtrant/s if nothing else. Bob Fenner> Lettuce Sea
Slug/Systems 4/10/06 I have 4 lettuce sea slugs
in my 29g reef (yeah, probably 2 if not 3 too many). <Maybe four too
many.> I have had them in there for a couple months. Only one of them
explores the entire tank, another explores sometimes, but the other two
and the "sometimes" one mostly hang out on the glass at the top of the
tank, in the direct flow of my power filter and obviously near the
light, and the two don't move hardly at all. I have a couple of times
taken them all and placed them within the rock but they end up back at
the tank top. My question is, is this considered "normal"? I
figured they are partially photosynthetic but they are getting little if
any solid food, other than what they may be filtering/catching in the
water flow. should I be concerned with their health? <Yes, the Lettuce
Sea Slugs are photosynthetic but need sufficient green algae to
survive. Without providing this they will soon perish.> they so far
don't seem to be adversely affected, at least on the outside.
