id please

Here is a frag a friend gave me. Whats strange is that the polyps only get bigger, they haven't multiplied at all and I've had them 2 1/2 months?
Would like to know something about them?

 

yeah 2in10 is probably right

 

That is a palythoa and I wouldn't change anything you are doing. It will eventually start to multiply.

 

I'd say slow growing but they've gotten huge in my tank, thx. any more info?

 

+1 on the ID Looking nice and big though!

 

The heads on that thing are like an inch across each, I think it likes my tank.

 

I would say so!!! Congrats, When you decide to place them on the rocks I would put them at the same height or lower.

 

Haven't gotten that far, I need to figure out how to place them on a rock.

 

Better pic

just looked at that pic again and realized it is BAD! So.

So how long dose it take for these guys to develop new heads? I've had them for almost a year and nothing.
