Clear Sun Coral looking thing??

this thing has been here for months and i really don't know what it is. at night and sometimes during the day it's tentacles are like 2 inches long. i don't know if it is bad or not. it looks like my sun corals only clear. it has a mouth and white spots on the tentacles like sun corals have yellow spots on their tentacles. i've never fed it but it seems to be doing good.

 

it looks like its either a mojano or aiptasia. if it is , you dont want it. like a weed.

 

yea i got joes juice but i dunno if its one of those guys cause wouldn't it be attacking my stick polyps right next to it? maybe ill squirt it anyway.

 

Get your self some joe's juice and follow the directions. If you don't kill it now you will have many more down the road.

 

It's a clear cup coral. I have quite a few in my tank. Harmless little guys.

awesome dude that's exactly it... thanks.. i knew it was some kind of coral

 

ill put up a picture of it extended at night to get a better look but it looks just like that picture just without that red. the rock it's on has two colonys of what looks like the dead version of them so maybe that guy just survived. i'm also noticing little ones like it on another rock that looks like them just way smaller
