Are these good guys or bad?

[zippy]

These started to multiply all over my tank, but they do not look like Aiptasia. I have those as well, but I have no idea what these are or how to kill them. Any help as always is appreciated.

For reference in size the mushroom is about the size of a quarter.

I can't tell if they are Mojano anemonea or Tulip Anemonies. Mojano normally have club or bubble-tipped tentacles. Tulips do not.

 

[zippy]

If they are either type, do they pose any threat? Or are they a fairly common reef inhabitant?

Mojano have a powerful sting that can irritate or even kill surrounding corals. They also reproduce at astronomical rates. Tulips are fairly harmless but will eat pods.

i vote majano!

Suggestions on how to rid my tank of them? Thanks.

Do they have any pink on the tips? I can't really tell by the pics either but, my tulips have pink on them.

No, there is no pink on the tips, just the green. OK, Carole, I'll give it a try, thanks, all.
