Suspected aiptasia (UPDATED 3/1/2011)

A cup coral. Not aiptasia. Also looks to not be bothering your parazoanthus. Cup Corals are common among parzoanthus corals. Thye require feedings and are a stony coral not a soft coral. They are also slow growing, and are hard to maintain. It will not bother your yellow parazoanthus and most likely I would be concerned about the para out growing the cup.

look up Astrangia danae

 

Mental Note: It disturbs me that most people resort to "kill it" on here. It is a harmless filter feeder not aiptasia. Please stop killing things because your unsure of what it is.

 

You tell me...

 

I dunno... look at the latest pic.

 

Looks like a small beaded anenome to me. I'd leave it awhile and see if it colours up and grows.

 

Is there any way to get a higher resolution picture.

 

Yes, but it wont be right away. Your right about the fact that it isn't bothering the coral. It is fully rubbed up against a polyp right now and the coral doesn't seem to be affected at all.

 

In your 666th post you suggested murder...

hahahaha

 

They will be fine. Parazoanthus are tough and grow quickly. Well with out a better picture i'm still going to say it is a harmless cup coral, extended from its stony base to feed on particles. They are one of the only montis that live in the Atlantic and generally come in orange/brown/green/ and a white color.

 

HAHAHA that was a disturbing find .
