Anemone pest?

[Letsarrange1]

Been having problem with these guys growing everywhere and I mean everywhere and stinging other corals. Does anyone know what they are? They look like anemones or palys with a thick base like a zoa.

There was another thread posted just recently where the "thing" in the tank had a green center like yours. Unfortunately the pic was too blurry to make out but a couple of the suggestions were aiptasia and mojano nems. The jury is still out on what it is in the other thread but yours are more defined and those look like tentacles. I didn't know either of these "pest" type nems could have green coloration. Other more knowledgeable reefers will chime in I'm sure. Hopefully it's neither of these but if you're noticing them stinging neighbors and they're taking over it sounds like you will have to start eradicating them.

They're Majanos, like my profile picture.They can be pests, but not on the level of aiptasia. Easy to kill off without worrying about spreading.

They look a lot like palys, you should be able to tell by looking at the base. Also, paly’s will close up, but won’t retract like an anemone. Do you have any rock flower anemones? They look kinda like those too, but it wouldn’t be common for them to be so close together and exactly alike.

They could be majanos, but typically when I have seen them the color has been more uniform.
