I know this is a bad pic but out of the 12 I took it's the best one. I've just recently started finding these guys grazing on the glass in my fuge after I noticed the first one in the display. I inspected a few of my corals, both SPS and softies and I don't see them on any of them.

It's hard to tell from the pic but the head is on top, and he has two 'ears' kind of like a sea hare. It has no ruffles and is completely smooth from what I can see. It's a very vivid red color, with a darker section in the middle which looks more like his innards as oppposed to a color scheme.

They range in length from about 1-2mm.

Gee, B, thanks for the informative response...

I did some research and found it to be this:

I saw them eating my Spirorbidae's which was a dead giveaway.

Anyone seen these in their aquariums before? Can anyone comment? David?

Seeing as V. elegans are found only in the Far-East Seas of Russia: Japan Sea - Peter the Great Bay and Kievka Bay (about 100 km to north from Kievka I didn't find this species). Kurile Islands - Kunashir Id. (both Pacific and Okhotsk Sea sides), I would say they are not what you have.
However it could quite posibly be a species of Vayssierea.
I'd need a much better picture than yours to tell you what you have, but if you have a plentiful, almost unlimited supply of Spirorbidaes then fine, otherwise they'll just starve to death when their food source runs out.

Thanks David,
I'm pretty confident that they're of the same family. Do you have any ideas of where I can find more examples of Vayssierea? Only two are shown on the sea slug forum.

My only concern is if they will start feeding on featherdusters once they run out of the Spirorbidaes. And, if there is an endless supply of Spirorbidaes they may never die off, and may feed on featherdusters anyway.

Either way, I would have no idea as how to erradicate them if I needed to, so it looks like we may be in it together for the long haul...

There's not a whole lot of info on them.
If it is a species of Vayssierea most likely this would be the one V. calcedonica

The easiest way to get rid of them is also the most time consuming; when you see one just pry it off the rocks with your fingernail.

The species in that link look just like them, but then again they're all so small and all kind of look the same...

I would guess there to be over 500 already in the system, so manual removal isn't an option. They just started popping out of nowhere.

There are also what appear to be eggs on the overflows. Looks like I'm going to have to sit back and see where this storm takes me... oh well..
