Emergency

[KurtReef]

Need help on getting a id on this. Found a few on one of my rocks. It almost looks like it has tenticals or sweepers out.

This is a ball anemone and harmless.
Unlike aptasia and Majano, I had one 2 years ago and it remained, had nice color and only one more ever emerged. They remain small and here is a puzzling fact as others stated they are a good anemone. Anemone ???
Ball Anemones are actually not anemones at all, it is actually a mushroom coral that is commonly confused by too many as a Majano Aiptasia. Unlike an Aiptasia, they are reef safe, they commonly stay closed during the day and open up at night. The tips if its anemone-like tentacles end with a ball tip giving it its' name
Also please refrain from posting a common question as emergency. Emergency is someone in crisis situation who is losing fish or coral, has a chemistry issue or tank leak and needs immediate attention
