What in the world is this??

These are the best pictures we could get.. It only comes out at night so it made it really hard to take the pic. it also seams to be light sensitive. If I have the flash light on it for to long it sucks in.. We cant see it at all in the day light... I hope its nothing bad.. And I hope some one can ID it so I can read up on it.. Thanks guys!!!

 

Looks like aiptasia - glass anemone - or a majano.. either way, you need to kill it before it spreads. Do a search on 'aiptasia' - PLENTY of info here on the site. Good luck!

 

Thank you!! We will be going to the fish store today!!! I dont want those taking over!

 

just use Aptasia X. I killed 3 today. Its cool to watch them implode a few seconds after u feed them.

 

Thats not aiptasia, I have some of these that come out at night as well, They havent givin me any trouble yet, they could be some sort of hydroid... that could be just as bad as an aiptasia anemone... so just keep an eye on it.

 

I think you may be right.. This is the closest picture I can find..
The differences between this one and the one in my tanks is the color and these ones have a longer base as well as tentacles than the one in my tank but its the closes picture I have sen.. How do you get rid of them??
