Rock anemone pic

[Aneata]

This was a hitch hiker who somehow survived through the cycling back in January then disappeared for a few months and just popped
up again almost 3X in size.

First pic he's about a half inch full extended. Second photo he's just under 2 inches.



If anyone has any info about these guys and what to do with him it would be greatly appreciated. Do I feed him now that he's bigger? I have a very lightly stocked 75 gallon soon to be reef tank.

It acutely looks nice, look like some sorta mushroom coral? But I don't think it's an Aiptasia

You can feed it a small piece of food if you like. Can you get a better picture of it? Something closer?
