1. astrae snail
2. looks like aiptasia
3. which one???????????
4. some type of tube worm,(feather duster)

Those are my guesses.

Let me take a crack at it as well...

1. Astraea ( The Grazing Snails, Part I - Turbo, Trochus, Astraea, and Kin by Ronald L. Shimek, Ph.D. - Reefkeeping.com )

2. Aiptasia sp. Nuissance anemone that you may want to get rid of.

3. You have lots of life forms in that image, sponges, a spirorbid polychaete and perhaps a rock boring clam. Not sure on the last one.

4. You have two life forms in the last picture, a feather duster type polychaete as Charlie mentioned, and some type of snail wich looks like a whelk to me (unless there's a hermit crab in there).

zhenya regards no 2...what can i do to get rid of them!? and what harm they do? regarding no 3 i think ur right cause sometimes it opens up and regards no4 no there is no hermit crab in it....ive read that hermit crabs are not suitable in a marine aquarium..is that right?? and why?! thanks

and except no 2 are the others good in the aquarium?! its beeen nearly 2 weeks my setup so im expecting that some life dies and start to notice new life... thanks for your help

Hi Daniel,

You can try mixing some Calcium Hydroxide (Kalkwasser) into a thick paste, similar to toothpaste, and lay that down on top of it for a while.

Some people heat this paste up in the microwave a bit and then do the job on the anemone. You can turn off all the pumps for a little while (say 20-30 minutes) to prevent this paste being blown off.
Another method is to mix the same ingridient into a thiner paste and use syringe to administer mixture directly into the mouth of anemone. It should die shortly and you can remove it from the aquarium then. Turning off all water movement for short period of time is beneficial as well in this case.

I've heard people also use lemon juce to inject into the anemones but never tried this method, so I can;t comment on if it works or not.

Try using search function on this forum using keyword Aiptasia and you should get plenty of threads on this critters, and how people are dealing with them.

and except no 2 are the others good in the aquarium?!

All of the life forms in your images are fine to have in aquarium, except for the Aiptasia sp. anemone and that whelk (which I am not so sure it is a whelk at this point in time). To identify a snail one need to take it out of aquarium into a shallow dish with some tank water and photograph the aperture(opening) of the shell with animal completely withdrawn into the shell. Plus couple of images of the shell from different angles. We can then perhaps identify it for you, or, we can try sending your images to a marine biologist to do that for you.

Hi Daniel,

Thank you for posting wonderful images of the snail, however it is not images that are required for identification. We need to look at the aperture of the shell to be able to identify it.
Having said that, it looks like a small whelk to me judging simply by the presence of the siphon and general shape of the shell. However, identifying gastropods requires degree in marine biolody and specialization in gastropods, none of which I posess unfortunately.
So, take what I said with a grain of salt and if you can get me couple of pictures of the aperture of this shell I can send them to a friend of mine who is highly qualified to identify your snail. Being that his specialty is marine gastropods. ;)
