Off white egg shape, small hole and "tentacles"

[Drvillen]

There are a few of these under one of my corals. Sorry for the blurry picture, If needed I will try to get a better shot of it. Looks kinda like a fat bodied feather duster. Any help would be great.

Hmmm I can't see from the pic, but it does sound like a q-tip (or scypha) sponge.

Here are some better pictures of it...
Right near the centre of the shot. Stupid Turbo Snail is almost in the way..

Yeah, that is definitely a q-tip sponge. They are reef-safe filter feeders. Hiker4twenty got it.

So if I want can I move it to somewhere so I can see it better or is that where they stay??

They prefer to live in shaded spots, so if you move it out in the light, it will probably wither away. If you keep it shaded and just move the rock that it's on so you can better see it, I think that will be fine. I wouldn't try to detach it from the rock -- it probably wouldn't survive. They do tend to reproduce fairly quickly, especially in nutrient-rich systems. If you start to see a lot of them and you don't like them, you can pull them off and throw them away.
