Put it in water and take a photo when it opens up, otherwise it's not clear.

Sponges.

Let them live, they are harmless.

Sorry, I took the photo and video with my phone.
Last night, a worm like this came out. The front half is white, and the back half of the body is pink.
In the video, it flies around.
When I turn on the light, it hides.

What is this LIVELINESS? A lot in the samp and a small amount in the main aquarium.

In your photo, this is a calcium sponge of the genus Sycon. Useful and, so to speak, necessary. I have a lot of them in my sample, and there are some in the aquarium, but fewer.
Photo for comparison.

These animals are a clear indicator of normal water quality. The more of them there are, the better—they are filter feeders. They are typical inhabitants of shaded and calm areas of the reef, where there is no potential threat to their existence.

Guys, thank you for the tips. Sorry, I was on edge, I will be more careful.

Can you tell me what this little coral is near the parazoanthids?
Tanya
It seems you have Mayano.
Patrick4439
I understand that the Mayano can crawl, while these open and close with the pink cover and do not move around the entire aquarium, but are only found in the area of the pink cover. They are pink themselves (the stems), and the tips are green, reflecting green in moonlight, but are often closed in moonlight.

Here, take a look, are they similar?

briarium or clavularia - choose.

Rather briararium. And clavularia looks more like an anthelia (with shaggy petals). Enlightened on the new "Russian R\central."
Tanya
I was looking at the topic from the first link, they don't look at all like what I have growing, they are more like a group and don't climb.
Guys, thank you.
They look similar to this link: only pink and green, not brown.
Bottom right photo.

Well, thank God it's not Mayano, because under favorable conditions they grow even more than Aiptasia and are harder to get rid of. But if it's still Clavularia or Briareum, then that's great.
Timothy
At night:
Clavularia - the "stem" of the coral remains, the polyp hides.
Briarium - both the "stem" and the polyp hide (i.e., only the "skin").
Well, and explained one "''''''".
Julie
This morning I took a photo. A little further on, there are purple skins of parazoanthids. There are insignificant algae growths on the rocks due to the absence of algae eaters.

There must be a beautiful clavularia - it will have a large white center later.

Briarium for sure! I have the same one, someone from the forum shared it once!! I can't attach it to the rock... it loves the current!
