I found this slug-ish like caterpillar/worm/no shell snail on a piece of my prolifera...any idea? I removed him and evicted him to the QT just in case.
I think he might be "absorbing" my caulerpa in the DT since all the other macro's are growing pretty well in the refg and the prolifera in the refg are deeper green and has already taken root unlike the ones where this guy is found.
Bang Guy? since you have seen them all

I also think its probably a Stomatella varia ...
Below is a bit of info I piced up on a quick google search:
Scientific Name: Stomatella varia
Classification: Mullusca
Common Names:
Description:
Stomatella look like a cross between a snail and slug. Their shell is fairly flat and inconspicuous compared to most snails. They are brownish green in color and seem to stay under about 3/4" in length. Stomatella can move very quickly for a snail.
Good or Bad?:
Stomatella are good additions to the reef tank. They are herbivores and feed upon micro algae in the reef tank.
Notes:
Stomatella are active day or night, but come out mostly at night and are fairly secretive during the day. A look at the tank walls after dark with a flashlight will usually spot this critters if they are present in the tank. They will reproduce in the reef tank, but don't seem to reach nuisance population levels. Breeding has been observed during the daytime with all individuals climbing up to high points on the live rock and simultaneously releasing their eggs and sperm into the water. This can cause the tank water to look milky for a short time, but is nothing to worry about. The filter feeders get to eat well when this occurs.

The green slug in question has no shell. All it does all day is hang on the back of a piece of prolifera. It doesn't even move when poked.
The top view looks almost exactly like the side view except it has 2 very faint dotted lines running down the sides. It also has 2 land snail like antenna "eyes".
Hope this helps

I believe what you have there is Elysia tomentosa. I wouldn't have had a clue except that a few weeks ago I was reading about the Caulerpa taxifolia problem in the Mediterranian. This Sea Slug (Yep, it's a Slug) is one of the very few animals that can eat C. taxifolia.
Apparently it's just as fond of Caulerpa prolifera.

I watched a show on it and I think if your talking of the same thing it is. It had something to do with that grass that ppl use in there saltwater tanks that some how got into the ocean and is spreading and they were using many diffrent way to get read of it one was bleaching with a giant rubber seal that held it in but everything under the rubber mat died including fish and what have you. The other thing they were thinking of using was this slugish looking snail thing it ait this "weed" I use weed lightly cause it is in saltwater tanks but not found in many oceans. They were thinking of using it to eat this "weed" away and they were testing it all it ate was the plant it wouldnt touch corals or such and they said it wasnt uncommon if your ordered this plant to get some on it. That is the only way they found it they orderd some of this plant to test and they were on it. If that is what Im thinking of it is good for a tank but it will eat all your plant.
