ID Please..Let's play "Mushroom or Majano"!

[TheRedOx]

These are some hitchhikers on my LR which my LFS said were mushrooms but I'm starting to worry that they're actually majano anemones because they are multiplying fairly rapidly and some nearby zoos have closed up for a few days now. The color is exactly as they appear. There's little baby ones on the same rock, probably about 8 or 9 in all. They haven't moved or anything like that - they do seem to have mouths like a lot of ricordea that I see and they have a yellowy/greeny glow under LED moonlights. The one on the left in the pics seems to be the biggest, he's about 2" in diameter. Thing is, when I do a Google image search for majanos, these don't really look like a lot of those...so keep and admire or seek and destroy? Thanks for your help..

Yuma ricordea actually.

 

[TheRedOx]

Cool, thanks guys! I was really starting to worry, quite a relief.

 

[LILBUDDHA]

Yuma ricordea actually.

What this person said ^^^^^^..

 

[wicked demon]

Yuma Ricordea, coralimorphian, closely related to anemones, will sting and possibly kill most other coral it comes into contact with.

 

[inactive]

Yes, very powerful sting... only takes minutes to destroy.

Yuma Ricordea, coralimorphian, closely related to anemones, will sting and possibly kill most other coral it comes into contact with.

Whoa, whoa...so they're still bad? Should I get rid of them or do they just need to be kept away from other corals?

 

[J&O'sdad]

Keep them just don't let them touch other corals. Good hitchhiker for once.

 

[Azurel]

They are no problem just keep them away from other corals as you do with most....People like me pay good money for single polyps of Ricordea yuma.....I wish I got hitch hikers like that....

Agreed with the group, it's a yuma ric. Mojanos have more "octopus like tentacles"
