A few photos for ID

[mykdf]

Below is a link to my photo bucket account. I've placed a few pics there to see if anyone can ID these various critters. I'm most interested in the first three - Nudi?, White Fluffy Things and Some Sort of Worm?. The other photos have been generally IDed but I'd love opinions on those as well. . .

Can anyone help with the IDs?

VacavilleFC3S-
Thanks for the response (again). And you are right that I've posted some of these photos before but as I said in my post. . .

"I'm most interested in the first three - Nudi?, White Fluffy Things and Some Sort of Worm?. The other photos have been generally IDed but I'd love opinions on those as well. . ."

I'm curious about your take on number three . . . the aptasia with a bi-valve underneath it. What if I told you that I have three in my tank that look just like that and that there is a clear/white . . . tube, for lack of a better term, that leads up to the head (picured)? It does appear to be some sort of annemonie or polyp or something . . . at least to my untrained eye.

For #1, touch it. If it reveals a white shell, it's a stomatella, which is a harmless algae eater. If it doesn't have a shell, it's a nudi and you should pull it. From the photo alone, it looks like a nudibranch...

#2 - is it sessile or does it move. It almost looks like a sponge, so you should be fine. If it moves and looks like a slug, pull it...

#3 - It's a aiptasia, with a vermetid snail next to it. It's a type of sessile snail that feeds via a muccus string. Completely harmless and since it's a larger species, you shouldn't have problems with them reproducing.

Here's an article on vermetid snails:

I agree with most of what has been said.

I think the photo labeled "Nudi?" is most likely a type of limpet, which I would gladly take off your hands if you don't want it or if you find others that you decide you do not want. There is additional information about them here:

The photo labeled "White Fluff" shows a sponge, at least that is the white stuff below the extended white wisps, and is likely the wisps as well.

The photo "some sort of worm" is a nusiance anemone of some sort.

The un-named photo looks to me like a typical hitchhiking tunicate. They are cool animals, and harmless.

The "more polyps" photo does appear to be some sort of zoanthid.

The "polyps" photo appears to be a paly.

The "slug?" photo I can't really comment on, as the photo isn't clear.

The "worm" photo is of a tube worm w/ a hard calicum tube.

This is the second time in one day that I said stomatella, but meant scutus. Look up scutus (limpet) and see if that is what is in picture #1...

In RE: photo 1- the nudi/limpet. I did not see any sort of shell on it. Although the picture does not show it well, there appeared to be small raised dots down its back. I think there were six total (two lines of three).
I would love to touch it as suggested by superstretch, but I haven't seen it since I took those pictures. I think I caught it because the tank was completely dark for a few hours . . . I came home and snapped on the lights to see what I'd catch (something I won't do when I've got my tank stocked). He slowly found a crevice and disappeared.

As for #3, the anemonies. . . should I Dave's Juice them?

AND thanks superstretch for that link on vermatids. That explains those mucus nets I was seeing!

The fact that the animal came out at night, and it sounds as though you have recently added live rock, would bolster the theory that the animal you saw is a Scutus, which is a type of limpet. If you read what has been written by folks in the link I posted previously, you will find many similar stories.

My father fly fishes, and is thinking about making a rod out of some bamboo cane that we have had drying for a few years now.
