ID on these?!

[GucciYoni]

Hey guys tank is 5 or 6 weeks old has cycled and has fish in it plus a sma cuc.

Are these Zoas and a barnacle?

 

[Palyzoa]

Zoanthids yes. The second one looks like it might be a majono? unsure on that one, but Im sure someone else will have the answer.

 

[GucciYoni]

I dont think they are zoanthids they grow out of tubes and my tank has no calcium. theyre growing out of thick tubes in the liverock and that huge one can retract into itself pretty sure the others are juveniles of the large one. Any ideas?

 

[Palyzoa]

Possibly palythoas or zoas? @A. grandis any ideas?

 

[GucciYoni]

Pretty sure they Cajanos

Looks like zoanthids for sure. The “tube” you’re referring to is its stalk... it’s stretching for light... the 2nd pic I’m not sure

 

[GucciYoni]

All of the organisms in the pics have the exact same colouring + feature, my lfs said my calcium levels are undetecable, which means it couldnt be zoas right?

I think they are an Majanos outbreak no?

Not sure zero calcium is attainable using any known salt mix, especially in a new tank. I agree it looks like some mad zoas and an anemone of some sort.
