those are all the same picture (for the most part)
looks like a pest whatever it may be.

kill it.

Thank you for your reply. Yes, the three pictures are similar shots of the same specimen. Unfortunately, I would like a more concrete identification of it before "killing it."

Out of curiousity, what visual criteria does one use to establish whether something is a pest or beneficial?

...experience based on observation ...

If you do not mind me asking, what specific observations did you make that allowed you to conclude that the specimen in the picture is a pest?

Thank you...
 
the length of the tentacles

its seems rather pale, allowing me to assume it can thrive without zooanthalae

it appears to be more aiptasia like than any other anemone

----------------------------------------


take the rock out of the tank and put in dark place for a week checking on it daily
if it seems the same after the week, color-wise and behaviorally, betcha its a pest.

cut off a section of a single tentacle, any size, and put that piece ina secure place and see if it survives and produces a new anemone...... pest...
 
What would be the recommended method to kill/remove it...assuming it is a pest? Would injection of lemon juice work? I have used this method to eliminate Aiptasia.
 
I don't think it is an anemone. If you look closely can you see a stoney base that looks like a miniature Euphyllia? I have some of those on my LR and I think they are of the Euphyllid/Carophyllid family.

...you can see a stony base ???
wow., and im seeing thru a 32" LCD w/ vid card :(

Vitaly, ...how does it retract when harrassed?
 
LOL, no I am asking him if he can see a stoney base. It looks like an oval with ridges. The ones I have in my tank are translucent blue in color but you can definatly see the base through it. Or when you kill it it will leave a skeleton like Galaxea corals. Mine also has 4-5 in the general area on the same rock.

If it doesn't then it is probably aiptasia.
 
That is commonly called a cup coral. They are non photosynthetic LPS type coral. If you feed them meaty foods like mysis they do very well and will grow. They look just like a clear sun polyp. You can even see through them and watch them digest a whole mysis. I have heard they have a pretty powerful sting, but they aren't fast spreaders, so it isn't much of a concern.

You can see a mysis in the bottom polyp in ithe bottom photo
