I first noticed this growing out of a rock a couple of months ago. I thought it might be aptasia so I squirted it with boiling water and it appeared to have died. About a week later it re-emerged, and has now grown to almost double in size. It's now about the diameter of a nickel. If I touch it, it withdraws into the rock like an anemone. It is getting larger, but I haven't noticed any others popping up.
Is it aptasia? Some other sort of anemone? Should I try to kill it?
