6 legs, white and moves

[strazdas]

I have been watching this creature in my tank for the last month or so but can't figure out what it is. Perhaps one of you know. I don't have a digital cam so I will do my best to describe it.

Grayish white in color
Has 6 arms/legs each with a 'v' at the end where the opening of the v is at the very end of the arm
It move pretty quickly
This morning it was sitting on my digitata but I have seen it on the back wall and out of the water holding onto the wire for a pump and climbing on rock.
It is about the size of a quarter in diameter

That's all I can think of to describe it. Any ideas?
Thanks in advance

Is it like a little lobster looking creature??

Nope, doesn't look like a lobster. Actually looks like a starfish except it has 6 arms. I don't see it often (like once a week or something for 5 minutes or so). Here's a little more info that may help

I can't see any eyes on the top side of its body.
It moves like a starfish meaning it uses its arms to hold onto glass and then to move.
I also have not seen a distinction between its body and its legs.
There are no bumps on its body/legs.
I have seen it in the daytime so I don't think its noctural but who knows.
I have never seen its underside so I have no idea what that looks like.

Next time I see it, I will try to observe more characteristics.
