creature identification

[lisat]

Hi can anyone help me identify this little polyp











type creature on my live rock I've had the system up and running for a month now and I first saw it when it was a bit smaller and moving along the rocks then it disappeared for a week or so and then appeared on the edge of a piece of my live rock and has firmly positioned itself there and hasn't moved since, I really like the look of it and hope its identified AS something good in my tank and not bad so any help would be much appreciated sorry about the photos my cameras not great....

Some sort of a zoanthid. Hard to give you a exact name as pic is pretty small. Hardy and usually fast growing.

OK thanks, I know the picture is rubbish! Are they a good edition to my tank.when you say fast growing do you mean they become more than one or they them self get large

With the correct water conditions it will multiply as well as get a tiny bit larger.

This is my colony of them...they will multiply faster the better the water condition in the tank and also depends on lighting

Sounds good and the picture of the colony of them looks really nice,thanks for all the help!!
