The resident ended up in the aquarium in December as a tiny creature (less than 5 mm), but now it has grown to almost 1 cm. It has a pink body with long tentacles of varying sizes. It prefers moderate lighting and hides in a hole in the rock during the day. Today, I decided to feed it shrimp, and it ate with pleasure. What kind of creature is this?

I also have something like this, what is it?

Is this a normal state of the polyp or is it "well-fed"? (Because you can also overfeed an anemone, which won't be brown in my tank; for fun, I feed it every day, the anemone sits without light... almost transparent but still eats... beautiful... in my opinion, it looks like Actinia bermudensis (McMurrich 1889) or Viatrix globulia (Duchassaing, 1850). Google images with these words. Then look for the characteristics of the taxon (mouth, number of tentacles, whether there is a clearly defined septum).

There is a suspicion that you have some type of "coral-like" Corallimorphidae, most likely Pseudocorynactis or, in fact, Corynactis (its mouth structure is specific). It is a non-photosynthetic organism, unlike its closest relatives, the Ricordea. I have two of them, one green and one reddish. I would fatten it up; as they grow to the size of a 50 kopeck coin, they change color and look beautiful, in my opinion. Maybe you could also look up some tricky zoanthids, such as Epizoanthus and Mesozoanthus.

Most likely Protanthea simplex
