So on one of my rocks I found this thing growing. It looks like a coral to be but I've never seen anything like this, could be an anemone but looks like a coral to me. Help would be appreciated

Thank you, this is the most bizarre hitchhiker i have ever seen but its pretty interesting.

So I saw that it had some tentacle out and when light was shown it retracted, could also be a worm too, but its not a barnacle since it didnt look like an arthropod

Well it has grown since i bought the coral, which has been there a very long time so it was a lot smaller originally.

So somehow a barnacle is able to stay alive in my tank, despite barnacles being very hard to keep alive in aquariums

It had a tentacle or something out but it retracted so quickly i couldn't see what it was

Its in a 40 gallon tank, i do feed reef roids daily so that may keep a barnacle alive given my sponge and corals are doing well. But this thing came in with the coral and has just been doing its own thing there for months, what kind of images would be best to identify it? Top down?

I havent ever seen a claw when I've looked at the tank at night. Also all the pictures of barnacles I've seen have different shapes and colors but not like this, so I dont think it is one, given they are filter feeders wouldn't they need a lot of food? Compared to a coral or sponge which i do have

Can someone help me identify what this thing is, its hard and feels like a shell of something, i have seen it grow over several months and am wondering what it is, its obviously some type of living animal since I've seen it grow in size, but what exactly is it? I can post more images if needed
