they should be ok if they have enough to eat (aiptasias) if they dont they will die i think someone in the message board is looking for one, find out if its what we think it is and get in contact with the other guy that is if you dont have aiptasias

the sooner you smash it the better the chances that they do not reproduce

Most Nudibranchs are harmless. I wouldn't worry about it unless I noticed it eating something I want but that's just me.

+1 on removal if its a nudibranch ( and it looks like one) -1 on harmless... there are NO nudibranches that are NOT predators. Period. Please see link at bottom of page. You can sit and wait for it to munch something you paid for but by then it will have reproduced, cost you $$, and probably hide again making it that much less fun to wait to find it and catch it again. Bring it to LFS for a very small credit and get something you know you want. Or, post if here for trade... Nudibranches info from Robert Toonen Ph.D. If you do a
search for "reef safe nudibranch" on the web, there are
literally hundreds of hits, but the vast majority of these
are either gravely misinformed or trying to sell you a line.
For example, I found several sites that listed "algae eating
purple and yellow nudibranchs" for sale that claimed these
slugs were "incredible algae eaters that will not harm any
invertebrates or corals!!!" Well, that information quite
simply wrong. First of all, no dorid nudibranch is
herbivorous, and there is a page of the Sea Slug Forum devoted
to dispelling some of the common
aquarium trade misinformation such as this. Quite simply,
although dorids are the most diverse group of opisthobranchs,
they are also among the most specific feeders of
all molluscs. The animals studied thus far are almost without
exception specialist predators that require one or at most
a few species of specific prey to survive, and in most cases
the animals will not even recognize perfectly suitable
alternatives as food! In any case, there are no true
nudibranchs yet discovered that are herbivores, so this
is either a big misunderstanding on the part of these suppliers,
or (and I hope this is not the case!) a deliberate ploy
to get consumers to buy a beautiful but completely inappropriate
animal before it starves to death.

Let me clarify. Most nudibranchs do not survive in our tanks. We don't have an environment where their food is available. In the several years I've spent intensely enjoying this hobby, I've seen that most Nudibranch are harmless to coral. Some do eat coral of course, but that may be because they cannot find their main food. Of course they eat something, but most often it's surface biofilm, surface algae, detritus and dieing/dead things. They can't move fast enough to eat anything that can get away from them. The fact that this nudibranch was seen in the tank, means that it was looking for food. The fact that it was on the glass, means it hadn't yet found any food on the LR. This is a newly set up tank. There is nothing much in there for a Nudibranch to eat and it will eventually die. If it were me, I'd watch it carefully because it's very fascinating. I'd let nature take it's course. Over the years, I've found that our tanks do much better if we let the amazing diversity of life flourish and even help it flourish by not trying to kill anything, except the known pests, of course. If left alone in this tank this Nudibranch will eventually fade away. If by chance it does end up on a coral (Zoanthids are the most common dinner) and starts munching away, then I would immediately remove it. It's that simple. Here's a story. Last night I was at Asad/seti007's home enjoying his company and his reef aquarium. As he moved a coral in his coral recovery tray, I noticed a crab that I at first assumed was a pale colored Emerald Crab. I said "Hey look there's an extra big emerald crab." Asad replied "Emerald Crab?? I don't have any Emerald Crabs in there." So I chased it down and caught it. Sure enough, it was a Rock Crab not an Emerald. Asad took it from my hand, as it pinched me, and tossed it into his Refugium. Anyone that has seen Asad's system, will acknowledge, that's why it all looks so amazing. Because he keeps every living thing and those things grow and they make for an amazingly beautiful and diverse reef environment.
